@EclipseMaster459 Well it makes a difference: Suomi (Finland) vs. suomi (Finnish -language).
Also, if a suffix includes a, that means it has a variant with ä instead due to something called vowel harmony. So when we speak of those, it's common to use -A to note that variation. -ssA rather than ssa/-ssä and there are lots of such things.
