I came across the following sentence:


I'm guessing it means something like:

You forgot me!

But what is happening / what is the meaning with the being attached to ちゃう's verb stem?

  • If that is the case what is いや? Because I would expect だめ, いけない, or ならない instead of いや Commented Sep 16, 2020 at 5:59
  • I deleted the comment because I didn't want to be answering in the comments, but いや is this jisho.org/word/%E5%AB%8C

  • I'm not sure I follow. If I expand わすれちゃ to わすれては the only grammar I know that uses this is the setup for Must not X and then I would expect だめ, いけない, or ならない following it. For example, I would expect the expanded version of the above to be something like わすれてはだめだ (You must not forget) Commented Sep 16, 2020 at 6:21
  • Other things can follow ては, since it's just another form of conditional, but I'll let someone else answer.

Pretty sure ちゃ is the shortened form of ては. では/ては can be used in a similar way to the conditional たら, but only for negative results. For example:

It will be a problem if you skip work when we are busy.

There are many other ways to use this grammar point, including what you mentioned in the comments.

You have to do it that way.

For your example, if you expand the sentence, it should become:

If you forgot me I would feel bad. (literal translation)
I don't want you to forget me. (natural translation)

いや・嫌 here just expresses that the speaker is emotionally opposed to this happening. So "If you forgot me, I would have negative emotions." I hope this helps :)
