Tsu-ku and Tsu-ku-ru （つくる）

I briefly introduced the very versatile verb <tsu-ku> in the last post.

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.
付く (つく, tsu-ku) - to attach. Intransitive verb.
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 at the end.
憑く (つく, tsu-ku) - to attach, mentally or psychologically. Intransitive verb.
搗く (つく, tsu-ku) - to pound (dough, rice, wheat, etc). Transitive verb.
点く (つく, tsu-ku) - to light up, to catch fire. 着く or 付く is also used for this use. Intransitive verb.

<tsu-ku> may have some relation with <tsu-ka-mu> for <to grip> and also <tsuku-ru, <tsuku-ru, つくる、作る> - an important word, the verbal form for creation.

搗く (つく, tsu-ku) - to pound  (dough, rice, wheat, etc). Transitive verb.

This 搗く (つく, tsu-ku) is not a very important word in the modern industrialized age now but was a very important word in the ancient time heavily based on agriculture (already developed over the hunting age) and is supposed to have been used a lot every day, and was highly likely the origin of <tsuku-ru, つくる、作る>
