It has been suggested that the reason why "amn't" is not as widespread as other contractions is that English tends to dislike the
nasal consonants /m/ and
/n/ together. In Scottish English,
amn't is generally used only when inverted as a question (i.e. "amn't I?"); in Hiberno-English it is also used in statements ("I amn't") and sometimes as a
double negative ("amn't I not?"):
- I'm going home, amn't I?
- Amn't I coming?
- I amn't going to work today.
- I'm not late, amn't I not?
