Adjective / Adjective-verb --> Verb Conjugations

I posted ＜Adjective  --> Verb Conjugations＞and stated ”We may see ＜Adjective-verb --> Verb Conjugations ＞ later." A fairly long time has passed since then.

Adjective-verb （Keiyou-Doushi or けいようどうし, 形容動詞）is neither an adjective （Keiyoushi 形容動詞 in Japanese）nor verb （Doushi 動詞）. Adjective-verbs seem to conjugate by changing the un-root part or a conjugation part (which follows the root part) - but unlike adjective not very systematically, which is less systematic than the verbs however. So some or many people think and regard the adjective-verbs not a grammatical unit (word group).

We have many or countless adjective-verbs as you can make new ones. I just picked out from the post ＜Adjective  --> Verb Conjugations＞ to start the argument. These are not adjectives but adjective-verbs.

i-ya-na （いやな） -  i-ya-ni-na-ru （いやになる）  -　( i-ya-ni-su-ru - no this verb) -  detestable -  to become detestable -  (   )
 i-ya-na （いやな） -  i-ya-ga-ru （いやがる） -　( i-ya-ge-ru - no this verb) -  detestable - to seem detestable  -  (   )

 i-ya-na （いやな） has a special verb conjugation <-garu> in addition to the common <-naru> conjugation.

ki-re-i-na （きれいな、綺麗な）-  ki-re-i-ni-na-ru （綺麗になる）-  ki-re-i-ni-su-ru （綺麗にする） -  beautiful(pretty) -  to become beautiful (pretty)-  to make st beautiful (pretty)

hi-ma-na （ひまな、暇な） -  hi-ma-ni-na-ru （暇になる） -  hi-ma-ni-su-ru （暇にする）（seldom used）　 - not busy (nothing to do)  - to become not busy  - to make oneself not busy. I cannot find one word adjective in English. <free>, <idle> are not exactly the same as hi-ma-na （ひまな、暇な）.

o-ku-byo-na （おくびょうな、臆病な） (Chinese origin) -  o-ku-byo-ni-na-ru （おくびょうになる） -（o-ku-byo-ni-su-ru （おくびょうにする） - no this verb) -  timid -  to become timid -  (   )
hi-kyo-na （ひきょうな、卑怯な）  (Chinese origin) -  hi-kyo-ni-na-ru （ひきょうになる） -　(hi-kyo-ni-su-ru （ひきょうにする） - no this verb) -  shrewd -  to become shrewd -  (   )

Among the above ki-re-i-na （きれいな、綺麗な） is a typical adjective-verb though this word is Chiense origin (ki-re-i 綺麗（きれい）) despite sounds like Japanese because of the sound <ki-re-i> which resemble an adjective which ends <-i> sound.

The typical Native Japanese origin adjective-verb is <shi-zu-ka-na （しずかな、静かな）> - quiet. We have an adjective ＜u-ru-sa-i うるさい＞for <noisy> but do not have an adjective for <quiet> and instead we have an adjective-verb <shi-zu-ka-na （しずかな、静かな）>.

Attributive and Predicative uses of an adjecive

adjective ＜うるさい＞

Attributive use  -   Noisy children  - 　＜urusai kodomo tachi ＞＜うるさいこどもたち＞
Predicative use  -  The children are noisy - 　＜kodomo tachi wa urusai＞＜こどもたちはうるさい＞

I think that the adjective ＜u-ru-sa-i うるさい＞ conjugates but in this case seems no change -＜urusai＞＜うるさい＞

Forget the other conjugations but Verb Conjugation or more correctly Verb-making Conjugation. We learned this in <Adjective-verb  --> Verb Conjugations>. By following the simple and universal rule.

＜u-ru-sa-i うるさい＞  ー＞　＜u-ru-sa-ku-na-ru うるさくなる＞ (intransitive verb) - to become noisy
＜u-ru-sa-i うるさい＞  ー＞　＜u-ru-sa-ku-su-ru うるくする＞ (transitive verb) - to make something/someone or oneself noisy

Almost all adjectives follow this conjugation rule: adjective root + ku-na-ru for an intransitive verb and adjective root + ku-su-ru for a transitive verb. Please see Post ＜Adjective  --> Verb Conjugations＞.

"
to-o-i （とおい、遠い） -  to-o-ku-na-ru （遠くなる） -  to-o-ku-su-ru （遠くする） -  far (away) -  to become far (away) -  to make st far (away)
ya-su-i  （やすい、安い） -  ya-su-ku-na-ru （安くなる） -  ya-su-ku-su-ru （安くする）  -  cheap -  to become cheap -  to make st cheap
a-tsu-i （あつい、暑い、熱い） -  a-tsu-ku-na-ru（暑くなる、熱くなる）  -  a-tsu-ku-su-ru （熱くする） -  hot  -  to become hot-  to make st hot

"

Please note the rule:  <urusa>, <to-o>,<yasu>,<atsu> without the final <-i> are the roots of the adjectives. And the final <-i> changes to <-ku> then add <-naru> or <suru>.


Now turn to the Adjective-verbs. First we check Attributive and Predicative uses of the Adjective-verbs as they are regarded as at least partially adjective as the name suggests.


ki-re-i-na （きれいな、綺麗な）

Attributive use  -   (a) beautiful (pretty, neat, clean) room  - 　＜kireina heya ＞＜きれいな部屋＞
Predicative use  -  The room is beautiful (pretty, neat, clean) - 　＜(sono) heya wa kirei-da (desu)＞＜（その）部屋はきれいだ（です）＞. <desu> is the polite form of <da>.

Please note that ki-re-i-na （きれいな、綺麗な）can have <da> at the end by adding it to the root (kirei) but the adjective <u-tsu-ku-shi-i> (meaning "beautiful") cannot. This is one of the most distinctive differences between Adjective and Adjective-verb.

shi-zu-ka-na （しずかな、静かな）

Attributive use  -  (a) quiet  room  - 　＜shizukana heya ＞＜しずかな部屋＞
Predicative use  -  The room is quiet - 　＜(sono) heya wa shizuka-da (desu)＞＜（その）部屋は静かだ（です）＞

Please note that <kirei> (Chinese origin) is regarded as the root of ki-re-i-na. Also please note that <shizuka> (Native Japanese origin) is regarded as the root of shi-zu-ka-na. This is important when we think about how Chinese words were imported to Japan say, 1000-1300 years ago. But this is another topic to consider and discuss.

Next we check Verb-making Conjugations of Adjective-verbs. This is rather simple and systematic and therefore easy to do.

ki-re-i-na （きれいな、綺麗な）

ki-re-i-na  （きれいな、綺麗な） - ki-re-i-ni-na-ru （綺麗になる） -  ki-re-i-ni-su-ru （綺麗にする） - beautiful (pretty, neat, clean) -  to become beautiful (pretty, neat, clean) -  to make something/someone or oneself beautiful (pretty, neat, clean)

shi-zu-ka-na （しずかな、静かな）

shi-zu-ka-na （しずかな、静かな） - ki-re-i-ni-na-ru （静かになる） -  ki-re-i-ni-su-ru （静かにする） - quite -  to become quite -  to make someone/something or oneself quite


In case of adjectives

the basic form (or the ending form しゅうしけい 終止形 in Japanese) of an adjective is <XX(root) - i> like <to-o-i>, <ya-su-i>, <a-tsu-i>. When changing it to a verb (intransitive or transitive) this final <-i> changes to <-ku> and then add <naru> ot <suru>. The underlined part can be regarded as Conjugation.

XX(root) - i   -  Basic form or the ending form
XX(root) - ku + <naru> or <suru> - Verb forms
The basic form <XXX(root) - i> is also used as the attributive use <XX(root) - i -YYY>.
or
XX(root) - i + YY -  Attributive form

Meanwhile in case of Adjective-verbs

the basic form (or the ending form しゅうしけい 終止形 in Japanese) of an Adjective-verb is <XX(root) - da (desu) > like <ki-re-i-da (desu) >,<shi-zu-ka-da (desu) >. When changing it to a verb (intransitive or transitive) this final <-da (desu) > changes to <-ni> and then add <naru> or <suru> like <kirei-ni-naru>, <kirei-ni-suru>, <shizuka-ni-naru>, <shizuka-ni-suru>. And when making the attributive form this final <-da> changes to <-na> and added the attributed word like <room>. The underlined part cannot be regarded as Conjugation, which is my opinion. And this is also one of the most distinctive differences between Adjective and Adjective-verb.


XX(root) - da   -  Basic form or the ending form
XX(root) - ni + <naru> or <suru> - Verb forms
XX(root) - na + YY -  Attributive form

What are the differences and things in common between the adjectives and the adjective-verbs ?

Differences

1) The basic (or the ending form) and the attributive form of an adjective have the same final vowel <-i> while the basic (or the ending form) of the adjective-verb has the ending of <-da (desu)> and the attributive form has <-na>.

2) The verb form of an adjective has the final vowel of <ku> while that that of the adjective-verb has the ending of <-ni>. In this regard , though rather redundant, let us look at again,

Adjectives

XX(root) - i   -  Basic form or the ending form    (the old form was XX(root) - shi)
XX(root) - ku + <naru> or <suru> - Verb forms   (the old form was also XX(root) - ku)
XX(root) - i + YY -  Attributive form   (the old form was XX(root) - ki)

Adjective-verbs

XX(root) - da   -  Basic form or the ending form  (the old form was XX(root) - nari)
XX(root) - ni + <naru> or <suru> - Verb forms   (the old form was also XX(root) - ni)
XX(root) - na + YY -  Attributive form   (the old form was XX(root) - naru)

In common

As <naru> and <suru> are originally verbs so although the pronunciation differs the adjective's <-ku> ending and adjective-verb' <-ni> endings are used as an adverb-making ending form for any possible (meaningful) verbs.

ya-su-i （やすい、安い）  －　ya-su-ku ka-u （やすくかう、安く買う）－ to buy cheaply
ya-su-i （やすい、安い）  －　ya-su-ku u-ru （やすくうる、安く売る）－ to sell cheaply
-----

shi-zu-ka-na （しずかな、静かな）  －　shizuka-ni hanasu （静かに話す）－ to speak quietly

We call these endings, <-ku>and <-ni> as "verb ending" (or ren-you-kei れんようけい　連用形) as it is followed by a verb.

Before closing I want to emphasize

<da> of the basic form or the ending form of Adjective-verb <XX(root) - da> does not seem to be a part of conjugation and rather simply added to the root as we can change this <-da> to <de-su>, <de-aru> or <de-nai> (not <de-aru). <da> is treated a helping verb meaning (implying) "definition, decision" (which are also controversial). But <da> and <de> of <de-su> and <de-aru>,<de-nai> are in the same origin. So,

Adjective-verbs

XX(root) - Basic form  +  da   (the old form was XX(root) - nari)
XX(root) - ni + <naru> or <suru> - Verb forms    (the old form was also XX(root) - ni)
XX(root) - na + YY -  Attributive form  (the old form was XX(root) - naru)

<ni> and <na> differ only in the vowel. One (ni) makes an adverb and the other (ni) makes an adjective. So the root of Adjective-verbs can be considered as strong and <ni> and <na> can be regarded as the adverb ending and the adjective ending respectively. Please also see the above old forms.

The similar thing can be applied to the old forms of adjectives.

Adjectives

XX(root) - i   -  Basic form or the ending form    (the old form was XX(root) - shi)
XX(root) - ku + <naru> or <suru> - Verb forms   (the old form was also XX(root) - ku)
XX(root) - i + YY -  Attributive form   (the old form was XX(root) - ki)

<ku> and <ki> differ only in the vowel. One (ku) makes an adverb and the other (ki) makes an adjective. <ku> and <ki> can be regarded as the adverb ending and the adjective ending respectively. But the root of adjective may not be so strong as the adjective-verb.

＜before＞ and ＜after＞ in Native Japanese

How do you say ＜before＞ and ＜after＞ in Native Japanese?

In terms of location

before - ma-e (まえ、Chinese character 前)
There is a car before me.  - Watashi no mae ni kuruma ga aru. わたしのまえにくるまがある。
As ＜ma-e (まえ)＞ is not a preposition but a noun you need to put an helping word ＜ni, に＞ (at).

behind - u-shi-ro (うしろ、Chinese character 後)
There is a car behind me.  - Watashi no ushiro ni kuruma ga aru. わたしのうしろにくろまがある。
As ＜u-shi-ro (うしろ)＞ is not a preposition but a noun you need to put an helping word ＜ni, に＞ (at).

after - a-to (あと、Chinese character is also 後)
I will go behind (after) you. （I will follow you.) - Watashi wa anata no ato kara ikimasu. わたしはあなたのあとからいきます。
As ＜a-to (あと)＞ is not a preposition but a noun you need to put an helping word ＜kara, から＞ (from).

We have no prepositions in Japanese we use helping words (jyoshi, 助詞) instead.

In terms of time

before - ma-e (まえ、Chinese character 前)
Two year before.  - ninen mae (ni)  にねんまえ（に）
As ＜ma-e (まえ)＞ can be used as a noun as well as a adverb you can omit <ni, に> this time. Adding <ni, に> is not a mistake.

behind - a-to (あと、Chinese character is also 後)
Two years later or after two years - ninen ato (ni)  にねんあと（に）
As a-to (あと) can be used as a noun as well as an adverb you can omit ＜ni, に＞ like ＜ma-e (まえ)＞.

＜u-shi-ro (うしろ)＞ is not used in a time frame.

Either English or Japanese you can find a strange thing.

In terms of location

before  - in front
after  - behind

In terms of time 

before  - behind, backward
after  -  in front, forward

You can find this in most other languages - in Chinese too. Why does this conversion between location and time happen ?
Possible answer: People tend to look back in time frame while we see forward physically in terms of location.

morning, daytime, noon, evening, night

Continuation from <yesterday, today, tomorrow>

morning - a-sa あさ（朝）, a-sa-ga-ta あさがた（朝方）
daytime, noon - hi-ru ひる（昼）, hi-ru-ma ひるま（昼間）
evening - yu-u ゆう（夕）, yu-u-ga-ta ゆうがた（夕方）
night - yo よ（夜）, yo-ru よる（夜）

<ga-ta がた> means "around (about)" in the above so < a-sa-ga-ta あさがた> means "around morning" and <yu-u-ga-ta ゆうがた> means "around evening".

<hi, ひ 日> of <hi-ru ひる> means "day" and "day time".

<ru > is used both in <hi-ru ひる> and <yo-ru よる> but the origin is not well known, and the stress (intonation) differs - hi-ru (ru is stressed) but yo-ru (yo is stressed).

<yu-u-be ゆうべ> means "evening" as well as "last night" or "yesterday evening".


sptt

yesterday, today, tomorrow

Yesterday, today, tomorrow are very frequently used in our everyday life. Not often as these three but the day before yesterday and the day after tomorrow are also used. How do you say in Japanese?

the day before yesterday - o-to-to-i  おととい
yesterday - ki-no-u or ki-no-o  きのう
today - kyo-u or kyo-o  きょう
tomorrow - a-su あす or a-shi-ta あした
the day after tomorrow - a-sa-tte あさって

These are all Native Japanese. We have the Chinese origin words for these and use in some occasions (usually in somehow official occasions and in writing) but we here only talk about the Native Japanese words.

Unlike English there seems no word for <day> used. <Day> is <hi, ひ（Chinese character、日)> in Native Japanese. Actually <day> is <hi, ひ> is hudden. As these words have been so frequently used the pronunciation has been deformed (changed).

the day before yesterday - o-to-to-i  おととい
The final syllable highly likely should have been <hi, ひ>.

yesterday - ki-no-u or ki-no-o  きのう
The final syllable used be pronounced as <hu, ふ>（used be written as ki-no-hu (fu) きのふ ）. This hu (fu) ふ may have originally been pronounced as <hi (fi), ひ>

today - kyo-u or kyo-o  きょう
Likewise the final syllable used be pronounced as <hu, ふ>（used be written as ke-hu (fu) けふ ）. This hu (fu) ふ may have originally been pronounced as <hi (fi), ひ> .

tomorrow - a-shi-ta あした
< a-shi-ta あした> also means "morning" although archaic. This may remind you that in German "(der) Morgen" (noun) means "morning" while "morgen" (adverb) means "tomorrow". The transitions processes are similar. Beside we have the following (not forward but backward).

<yu-u-be ゆうべ> means "evening" as well as "last night (evening)".

Transitive and Intransitive verbs in Native Japanese

The difference of Transitive and Intransitive verbs may be a great grammatical issue in any language and so is in Native Japanese. When one verb is defined as a Transitive verb in one language (say English) and the (almost) equivalent verb in another language (say Japanese) is defined as an Intransitive verb it causes a problem, and you will face this problem quite often when you learn Japanese.

Verbs show the perception of human beings how they see the world going on.


sptt

Two syllable verb + verb ＜tsu-ku＞ and verb ＜tsu-ke-ru＞

We once introduced the verb <tsu-ku> as versatile meaning verbs as below:

突く（つく, tsu-ku) - to push with some tool with a point. Transitive verb.

着く（つく, tsu-ku) - to arrive. Intransitive verb. Transitive verb is 着ける（つける, tsu-ke-ru). The accent shifts from <tsu> to <ke>.

付く（つく, tsu-ku) - to attach. Intransitive verb. Transitive verb is 付ける（つける, tsu-ke-ru). The accent shifts from <tsu> to <ke>.

衝く (つく, tsu-ku) - to attack at a narrow area. Transitive verb.

尽 く (つく, tsu-ku) - to use up, to reach the end. Transitive verb (as taking を(o) after a direcr object) or Intransitive verb (in case of not taking を(o) and no direcr object)

憑く (つく, tsu-ku) - to attach, mentally or psychologically. Intransitive verb. Seems no Transitive verb.

点く (つく, tsu-ku) - to turn on, to catch fire. 着く or 付く is also used for this use. Intransitive verb. Transitive verb is 点ける（つける, tsu-ke-ru). The accent shifts from <tsu> to <ke>.

When we use a Chinese character in writing the meanings differ but the pronunciations are all the same, which means no difference in pronouncing and hearing them. In Tokyo accent (regarded as the standard Japanese) <tsu-> of <tsu-ku> has an accent when the verbs work an intransitive verbs while <-ku> of <tsu-ku> has an accent when the verbs work as transitive verbs (two verbs - 突く（つく, tsu-ku) and 衝く (つく, tsu-ku), very similar meaning) and 尽 く (つく, tsu-ku).

尽 く (つく, tsu-ku) (to use up, to reach the end. Transitive verb.) is still used now but an old form and limited in use. One example: ＜kane ga soko-wo tsu-ku (金が底を尽 く), literally, the money reaches the bottom.＞The modern form is

尽きる (つきる, tsu-ki-ru, the accent is on<-ki->). The meaning remains the same - - to use up, to reach the end but Intransitive verb.

-----

Now we will use  <tsu-ku、つく> and <tsu-ke-ru, つける> to make four and five syllable verbs, respectively by adding one of these to the two syllable verbs we leaned before. <tsu-ku、つく> and <tsu-ke-ru, つける> become more versatile in this way. This is a verb making play and you may get very easily more than 100 new Japanese verbs by playing not to mention <without tears and toils>.

The important thing is that you cannot simply add  <tsu-ku、つく> or <tsu-ke-ru, つける> to a Two syllable verb. You must change the form of a Two syllable verb, to which <tsu-ku、つく> or <tsu-ke-ru, つける> is  added. The Two syllable verb which you shall add <tsu-ku、つく> or <tsu-ke-ru must be changed its form, which we could call Japanese verb conjugation and very grammatical and simple.

1.  ending <vowel u>

i-u (いう、言う) - to say  －－＞i-i-tsu-ke-ru (いいつける、言いつける) - to let someone know by reporting
o-u　(おう、追う) - to follow  －－＞o-i-tsu-ku (おいつく、追いつつく - to catch up
ka-u  (かう、飼う） - 2) to feed (an animal)
ka-u  (かう、買う） - 2) to buy
ku-u  (くう、食う) - to eat (vulgar), the polite form is <ta-be-ru> (たべる、食る）.

ko-u  (こう、1) 乞う、2) 請う) - 1) to beg, 2 )to ask for

su-u  (すう、吸う) - to swallow, to absorb, to take (a breath), to smoke (a cigarette)
so-u  (そう、1) 沿う、2) 添う) - 1) to go (be) along with, 2) to accompany 
to-u  (とう、問う) - to ask (a question)

na-u  (なう) - to twist (straws to make a rope). Rarely used in the modern life.
nu-u  (ぬう、縫う) - to sew

ha-u  (はう) - to crawl, to creep

yo-u  (よう、酔う) - to get drunken, to get seasick, or more generally to get motion sickness

Not many combinations are used. Most of the above <-u> endings are originally <-hu> ending. <hu> is a rather special pronunciation so it is a bit difficult to produce it the same or very similar manner by different people and so to hear clearly.
No analysis on these verbs as I cannot find any rules or groupings in them except only 1) one verb in the <-i> row and 2) no verb in the <-e> row, which is common for the other groups too and typical in the verb making system. This is probably because <i> and <e> are not so clearly pronounced (closed or backward vowels) and not so clearly heard either while<a> and <o> are clearly pronounced (open or front vowels).

The <o> rows misses <so-ku>, < ho-ku>, < mo-ku> but they have the variants <so-gu>, < ho-gu>, < mo-gu>as shown belwo in <-gu> ending.

o-su,  ko-su,  so-su,  to-su,    no-su,  ho-su,  mo-su,   yo-su,  ro-su, ---


o-su (おす、押す)  - to push
ka-su （化す、課す、嫁す）are Chinese origin.
ka-su (かす、貸す)  - to lend, to rent
ki-su　(きす、帰す、期す、記す）are Chinese origin.

ke-su (けす、消す)  - to extinguish, to erase
ko-su (こす、1) 越す，2)濾す)  -  1)to cross over, 2) to distill
sa-su (さす、指す　刺す、差す、挿す)  - 1) to indicate, to point out (指す), 2) to pierce, to sting (刺す), 3) to insert (差す、挿す)
shi-su (しす、死す) - Chinese origin. <shi (死)> + <su>. Refer to <shi-nu>.
ta-su (たす、足す)  - to add


na-su (なす、成す)   - to make, to achieve
no-su (のす、伸す、熨す)  - to lengthen, to flatten
hi -su (ひす、比す、秘す) 　are Chinese origin.　
hu-su (ふす、伏す)  - to crouch
ho-su (ほす、干す、乾す)  - to dry
ma-su (ます、増す)  - to increase (as Transitive verb)
mu-su (むす、蒸す)  - to steam
me-su (めす、召す)   - to call sb to come, to invite (in polite form, to eat, to ware)
mo-su　(もす、模す）　Chinese origin.

mo-su (もす、燃す) - to burn
yo-su (よす、寄す) - to gather st (to make st close) to (a certain point, side, place) (Transitive), to become close to st (Intransitive)
yo-su (よす) - not to dare to do, to give up xx-ing

We must be careful in this group as <su> is the helping verb <su>, a part of <su-ru> (to do), having a function to change a intransitive verb to a transitive verb. So, <na-su> can be considered as an independent two syllable verb but can be regarded as the transitive verb form of  <na-ru> (to become), ie   <na-ru> + <su> (to make) combination and <na-su> means <to make become>.  <ka-su> is also <ka-ru> (to borrow) + <su> --> to make borrow --> to lend. <mo-su> = <mo-yu> (to burn) + <su> --> to make burn.
Because of this <su> nature almost of all the above to syllable verbs ending <su> including the Chinese origin ones are Transitive verbs. some exceptions -  shi-su (しす、死す) is Intransitive (to die). sa-su (さす、差す) is sometimes used as Intransitive (to get (to come) in at a narrow space)
It is a way (an easy way) to make a Chinese verb to the equivalent Japanese verb - to add <su> in old time or <su-ru> in modern time to the Chinese verb. <su> or <su-ru> is necessary because without these the Chinese verb cannot conjugate in Japanese. The Chinese verbs, nouns, adjectives do not conjugate at all. So if you already knows Chinese verbs you can used your Chinese verbs to make Japanese verbs with relative ease. But your Japanese  may sound more like Chinese when speaking while you may be regarded as more highly cultured when writing in this way.


<su> has the voiced sound <zu>

-zu

a-zu,  ka-zu,  sa-zu,  ta-zu,  na-zu,  ha-zu,  ma-zu,  ya-zu, ra-zu, wa-su

i-zu,  ki-zu,  shi-zu,  chi-zu,  ni-zu,  hi-zu,  mi-zu,  yi-zu, ri-zu, ---

u-zu,  ku-zu,  su-zu,  tsu-zu,  nu-zu,  hu-zu,  mu-zu,  yu-zu, ru-zu, ---

e-zu,  ke-zu,  se-zu,  te-zu,  ne-zu,  he-zu,  me-zu,  ye-zu, re-zu, ---

o-zu,  ko-zu,  so-zu,  to-zu,  no-zu,  ho-zu,  mo-zu,  yo-zu, ro-zu, ---


<zu> used to be used (or is used even now) as the helping verb (auxiliary verb) meaning <not> so it cannot be used as verb ending <-zu> to avoid confusion. However if you add one vowel after <zu> you can make some verbs like:

ki-zu-ku  (1) きづく、 1) 気付く；  2) きずく、築く)  － 1) to notice, 2) to build
tsu-zu-ku  or tsu-zu-ku (つづく、続く) 　－1) to cntinue, 2) to follow
ne-zu-ku  (ねづく、根付く) 　－ to become rooted
ha-zu-su  or ha-zu-su  (はずす、外す)　－　to set something aside
ha-zu-mu  or ha-zu-mu (はずむ、弾む)  －　to bound (up and down)
me-zu-ru  (めずる、愛ずる)  － to love, to be fond of
yu-zu-ru or yu-zu-ru (ゆずる、譲る)  － to give away


2 -3  -tsu

a-tsu,  ka-tsu,  sa-tsu,  ta-tsu,   na-tsu,  ha-tsu,  ma-tsu,  ya-tsu,  ra-tsu,  wa-tsu

i-tsu,  ki-tsu,   shi-tsu,  chi-tsu,  ni-tsu,  hi-tsu,   mi-tsu,    (i-tsu),  ri-tsu, ---

u-tsu,  ku-tsu,  su-tsu,  tsu-tsu,  nu-tsu,  hu-tsu,  mu-tsu,  yu-tsu,  ru-tsu, ---

e-tsu,  ke-tsu,  se-tsu,   te-tsu,    ne-tsu,  he-tsu,  me-tsu,  ye-tsu,  re-tsu, ---

o-tsu,  ko-tsu,  so-stu,  to-tsu,   no-tsu,  ho-tsu,  mo-tsu,  yo-tsu,  ro-tsu, ---


Not many, especially in the modern forms. This may be because <tsu> (つ) used to be used (or is used even now) as the helping verb (auxiliary verb) showing <past> or more like <perfect>.  The modern version of this <tsu> is <ta>. It is also used as the helping word (not verb) <tsu> (つ) or <tsu-tsu> (つつ) indicating or implying (not clearly showing) the meaning of <while xxing> or <to be xxing>. To avoid confusion there are not may verbs ending <-tsu> although the origin is not sure. Because of these <tsu> was limited to avoid confusion.

a-tsu --> modern form <a-te-ru> ( あてる、1) 当てる、2) 充てる、3) 宛てる)  - 1) to hit; 2) to assign; 3) to addreee
u-tsu (うつ、打つ)  - to hit, to beat, to strike, to flap
o-tsu --> modern form <o-chi-ru> (おちる、落ちる) to fall
ka-tsu (かつ、勝つ) - to win
（ke-tsu）　--> modern form <ke-chi-ru> (けちる、ケチる)　（＊）（ke-tsu）is not sure as the old form.
ku-tsu  --> modern form <ku-chi-ru> (くちる、朽ちる) to get old and fall
su-tsu (すつ、捨つ）--> modern form <su-te-ru> (すてる, 捨てる)  - to throw away, to dispose
ta-tsu (たつ、1) 立つ、2) 発つ、3) 経つ、4) 絶つ、5) 断つ、6) 裁つ) - 1) to stand up, to appear; 2) to leave; 3) to pass (time); to cut; 6) to cut (cloth)
ha-tsu --> modern form <ha-te-ru> (はてる)  - to end
ma-tsu (まつ、待つ) - to wait
mi-tsu (みつ、満つ） -->  modern form <mi-chi-ru> （みちる、満ちる) - to fill (intransitive verb)
mo-tsu (もつ、1) 持つ、2) もつ)  -1)  to have , to hold; 2) to endure

<tsu> has the voice vowel <dsu> but this <dsu> is almost same sound as <zu> now.


2 -4  -nu

a-nu,  ka-nu,  sa-nu,  ta-nu,  na-nu,  ha-nu,  ma-nu,  ya-nu, ra-nu, wa-nu

o-nu,  ko-nu,  so-nu,  to-nu,  no-nu,  ho-nu,  mo-nu,  yo-nu, ro-nu, ---

I  have fund only one verb in this group - shi-nu. <nu> used to be used (or is used even now) as the helping verb (auxiliary verb) showing <past> or <perfect> so it cannot be used as verb ending <-nu> to avoid confusion.  <shi-nu> (しぬ、死 ぬ) seems an exception. But <shi> is not the original Japanese but came from China (死, now pronounced as <si> in Putonghua). And <to die> is usually used in the past or perfect <died or have died>. <shi-nu> is not the original Japanese two syllable verb.


2 -5  -hu

<hu> was merged to <u> so no verbs ending with <hu> now. But <hu> has the voice vowel <bu> and <bu> is used as the verb ending.

-bu

a-bu,  ka-bu,  sa-bu,   ta-bu,   na-bu,  ha-bu,  ma-bu,  ya-bu,  ra-bu, wa-nu

i-bu,  ki-bu,  shi-bu,  chi-bu,  ni-bu,  hi-bu,  mi-bu,   yi-bu,  ri-bu, ---

Not many and only, only four verbs in the <o> row and two of them are ols forms.

o-bu --> modern form <o-bi-ru> (おびる、帯びる) - to have, to show
to-bu (とぶ、1) 飛ぶ、2) 跳ぶ) - 1) to fly; 2) to jump
no-bu --> modern form <no-be-ru> (のべる、1) 述べる、2) 延べる) - 1) to tell; 2) to extend, to lengthen

The above Japanese and English seem rather complicated.  This is because I have added possible old forms and shown in italic, some of which are still used now without noticing them as old usage. As far as the modern uses are concerned the possible combination are not too many not to few or relatively many and especially in the <a>, <o>and <u> rows by following the general rule. You can find the modern forms easily by seeing only the bold typed verbs. The old verbs have changed but in a very regular way. This has brought me an grammatical interest so I will explain this more below.

I use the differentiation of Transitive verb and Intransitive verb for this group for more systematic understanding. Please note again <he Japanese verbs are used in fairy different grammatical structured from the English. Some verbs are regarded as used as transitive verb and some are regarded used as intransitive verb but the differences are not so distinctive as English>.

<ma-ru> and <me-ru> as quasi-helping verbs

Like <to become> and <to make> in English we have the following very regular and almost universally usable ways to change an adjective to an intransitive verb (to become) and transitive verb (to make)

ha-ya-i  (fast, early： はやい) --> ha-ya-ku-na-ru  (to become fast (early) or faster (earlier)) --> ha-ya-ku-su-ru (to make st  fast (early) or faster (earlier))
o-so-i  (slow, late: おそい) --> -so-ku-na-ru  (to become slow (late) or slower (later)) --> o-so-ku-su-ru (to make st slow (late) or slower (later))

Note: In Japanse  fast and early are expressed by the same adjective <ha-ya-i> so as slow, late by <o-so-i>.

Besides these universal methodｓ we have some other method,which may be more old but simpler ways by using <ma-ru> and <me-ru>.  But these methods are not universal but limited some original Japanese adjectives.

Adjective +  <ma-ru> and <me-ru>

Adjective + <ma-mu> ---> to become  more and more
e.g.
ha-ya-i (はやい) - fast, eraly;  ha-ya ma-ru (はやまる) ---> to become faster and faster, to become erlier and ealier
ta-ka-i (たかい) - high, exensive; ta-ka ma ru (たかまる) ---> to become higher and higher, to become more andmore exensive
a-ka-i (あかい) - red; a-ka ma ru (あかまる) ---> to become reder and reder (can be ued and gramatically correct but not a common way of saying, the common way of saying ---> a-ka-ku na-ru あかくなる)

Adjective + <me-mu> ---> to to make more and more
e.g.
ha-ya-i (はやい) - fast, eraly;  ha-ya me-ru (はやめる) ---> to make faster and faster, to become erlier and ealier
ta-ka-i (たかい) - high, exensive; ta-ka me ru (たかめる) ---> to make higher and higher, to become more andmore exensive
a-ka-i (あかい) - red; a-ka me ru (あかめる) ---> to make reder and reder (the common way of saying ---> a-ka-ku su-ru　あかくする)

English use similar ways like

strong - to strengthen
weak - to weaken
white - to whiten
black - to blacken
(this method may be the old original English way)
-----
solid - to solidify
soft - to soften
simple - to simplify
glorious - glorify
-----
neutral - to neutrlize
equal - to eaualize

Multple meaning two syllable verbs

The meanings of each multiple meaning verb seem different but there are something in common so the root or very general meaning is the same, which may help to you keep the meanings in your memory. Actually the word has multiple meanings only when you use the Chinese characters.
