Does the phrase がんばする makes sense?


Person A: 頑張って{がんばって}！

Person B: ありがとう！ **がんばする** ！

Is it right to use that last phrase by person B?




> Is it right to use that last phrase by person B?

The answer can be yes or no. がんばする is understandable, but is far from
standard. You should avoid using it if you are still learning how to write
standard and correct Japanese sentences. Of course the correct form is がんばる,
which is a godan verb.

That being said, if you really saw ガンバする said by a native speaker in an online
chat or such, it's probably not a typo, either. Native speakers often play on
words and use funny and loose expressions knowing they're not standard, and
ガンバする is one of such examples. Actually ガンバする is not entirely baseless because
"ガンバ!" on its own is recognized as a (bit outdated) expression meaning "hang
in there!" or "do your best!" (hence the name [Gamba
Osaka](https://en.wikipedia.org/wiki/Gamba_Osaka)). ガンバする is not common enough
to be called an established slangy verb, but you can easily find real examples
of it with a simple Google search.
