What does 「見ちゃいない」mean?


I came across this in a manga, and I still can't figure out what the ちゃいない
means. Does any help please?




It's almost certainly a contraction of 見てはいない ("[someone] is not seeing it" or
"[someone] has not seen it"). It can also be a contraction of 見てしまいなさい ("Watch
it anyway!") at least in one western dialect I know, but it's rare.

In casual speech, ては very often contracts to ちゃ (and では contracts to じゃ). See
[Purpose of adj+kucha and noun+ja in this
sentence](https://japanese.stackexchange.com/q/57943/5010) for example.
