Verb[て] + Verb - 頑張って見るよ


> 頑張って見るよ

What does this mean? To me, it feels like "Try my best and see".




(-て)みる is one of the Japanese [subsidiary
verbs](https://japanese.stackexchange.com/q/18952/5010) that means "to try
V-ing". As a subsidiary verb, the original meaning of "to see" has been lost,
at least partly. (Compare how, in English, "have" as in "I have to do" or "go"
as in "I'm going to do" has lost its original sense of having or going.)
Subsidiary verbs are usually written in hiragana in formal writings, but some
people don't pay enough attention to this rule and use kanji anyway.

Note that (-て)みる means "to try V-ing", not "to try to V". See: [What is the
difference between "verb＋て＋みる" and
"verb＋(よ)う+とする"?](https://japanese.stackexchange.com/q/19038/5010)

So 頑張ってみるよ means "I'll try my best (anyway, and see what happens)". 頑張るよ just
means "I'll do my best", and てみる adds the implication that the speaker is not
sure about the result.

In non-typical contexts, 見る can be taken literally; "I'll try hard and watch
it (e.g., the TV program broadcast at 3 a.m.)". Check the previous context.
