The sentence in question is the following.

その しゅくだいを やりおわったら、 ちょっと こちらを てつだって くれませんか。

I can't figure out what やり is supposed to mean here since there is no kanji present in the sentence. I'm guessing the first part of the sentence means If you're done with that homework, but none of the やる verbs in the dictionary have a meaning close to that.


As far as meaning,

「やる」=「する」=「行{おこな}う」 = "to do"

「やりおわったら」=「しおわったら」 = "when you are done with ~~"

「やる」, in this context, means "to do". It is a little more informal than 「する」 and much more informal than 「行う」. It is an extremely common meaning of 「やる」, which has many meanings.

See definition #6 here in デジタル大辞泉{だいじせん}.


I am not sure what you mean by the word "stem" here, but certainly the origin goes way back to even around from 10th to 14th century.. The original kanji form varies, for example 遣(や)る 遣(=meaning, send, summon, give, ) as a transitive verb, from above 徒然草 ( English Wiki ),

The Japanese original


The Japanese modern version


English Tranlslation

(The person who buy the cow) says he will pay ( = give ) the money tomorrow and receive the cow.

or a subsidiary verb やる such as from 源氏物語 ( English ) to denote, do, finish.

The Japanese original


The modern Japanese


The English translation

(The mother, due to her deep grief) was not able to finish to say to the last, crying and choking with..

The conjugative form is ( basically ) ラ行五段活用

So the conjugation form is

語幹(stem) や(or遣)

未然形(Imperfective) ら

連用形(Conjunctive) り/っ

終止形(Predicative) る

連体形(Attributive) る

仮定形(Conditional) れ

命令形(Imperative) れ

So among out of various meanings your speech やりおわったら

will denote using, "to do" or "have finished XXX",

when ( you ) have done XXX

The translation of your whole sentence

その しゅくだいを やりおわったら、 ちょっと こちらを てつだって くれませんか

After you have finished the ( your ) homework, could you help me ( mine ) a little bit too?

Have a nice day.

    Some books for learners call the 連用形 form of a verb "the stem", although I'm not quite sure why. – snailplane Aug 9 '15 at 14:32
