Is 見てない short for 見てあらない?


The sentence

> それは見てないな。

apparently translates to

> I haven't seen that.

According to jpdb.io the word 見てないな is the "て-form negative" conjugation.

Does this mean 見てない is actually just short/slang for

> 見てあらない

and the literal translation of the original sentence is something like

> As for that, I am not seeing.

?




In the present progressive (て + いる), the い is often dropped. Thus, 見てない =
見ていない (short form of 見ていません)! :)
