A’m don it!

Shaetlan expresses the perfect tense with a form of BE: A'm seen da film aaraidy, but du isna / Y'ir been dere afore, but shø isna / Dey ir aa pitten oot der essybags, onnly we irna. This is different from Standard English, where the perfect is expressed with a form of HAVE (I've seen the film already, but you haven't / You've been there before, but she hasn't / They have all put out their bin bags, only we haven't). In other words, StE uses the same form for the perfect as for possession (to HAVE something: I have a phone / She has a cat / They have a house / etc). This is extremely rare globally: only 6.5% of the languages that have perfect do this, and they are all found in Western Europe. This makes StE much more unusual than Shaetlan for this part of the grammar.
