I do not understand the following construction using -tte iu nara


[![goku says ~ni modoru tte
iunara](https://i.stack.imgur.com/0HDnt.jpg)](https://i.stack.imgur.com/0HDnt.jpg)

Goku (the character speaking) says “~ni modorutte iunara” here, and I’m not
sure what it means.

I can only guess the “iu” means “say” and the “nara” is used to state an
authorative truth, but that only makes half sense.

Translations of this are not literal enough (“if you agree to go back to …”)
to understand the grammatical nuances here.

What does it really decompose to?




I think I understand now from the comments, I was getting hung up on a complex
meaning of nara - that may not exist.

The iu just stands for “say”, so “if you say you will return to .., then, …”

Silly, I know
