Do you have any examples? As a Finnish speaker the Swedish "a" sounds the same. "Pappa", "framtiden" etc.

It's "ä" and "e" which have swapped uses, but it's not exactly consistent (e.g. "Järnvägstorget" where first ä is close to the Finnish ä, second ä is closer to e but so is the e at the end)

Ä in Swedish is an æ sound.

Ä in Finnish is a pitched A sound, like the A in “cat”.

The pitched “a” in Swedish is the default one.

Wikipedia lists both "cat" and the Finnish "mäki" under æ: https://en.m.wikipedia.org/wiki/Near-open_front_unrounded_vo...

Do you have some example words that would show the difference?
