How to interpret 入っちゃって as a command?


A mother is telling her kid: 「お風呂わいたから入っちゃって」. From the context, I am guessing
it means "The water's heated up, come in (take the bath)!".

I don't understand how「入っちゃって」 could mean a request / command here. Is 「っちゃ」is
short for 「しまう」or 「ては」? Neither makes sense to me here. And what is the role
of the final「って]?

Thanks!




First, yes, てしまう is commonly contracted to ちゃう (and でしまう to じゃう). They mean
the same, but ちゃう is more casual as a contracted form.

Second, as for the meaning of しまう・ちゃう here, I think the slightly less common
usage of "do completely" fits, with ちゃって being itself the て-form of ちゃう,
making it a casual/friendly request. This usage is very common, and is derived
(I believe!) from just dropping the ください that you might expect to see there.

So, putting those together, you could translate 入っちゃって as "get in completely"
or "get in fully". Perhaps more stylishly, you could translate the sentence as
"The bath's hot, so get right in".
