As I was writing an answer in another SE language forum, I used "words in -act" for words ending in -act like impact or contact.
Words in -act are always pronounced /akt/
I said this both as a calque from French and as short for "ending in -act". Now I wonder, is this correct at all?
I know I can say "words ending in" or "words ending with" but it's a little heavy, is there a shorter way to say it?
