ö  Ö

Swedish legacy — rare in core Finnish

There is also y — already in your alphabet, but Finnish uses it as a front vowel. Lips forward, like French u. It appears in tyhjyys (emptiness), (night), kymmenen (ten).

vowel harmony
the rule that explains the code
back register
a  o  u
front register
ä  ö  y

a word uses one register or the other — never both. suffixes follow: talossa (in the house) vs metsässä (in the forest). same grammar, different vowel.

This is why Finnish looks like a cipher to new eyes. The diacritics are not decorations — they mark which half of the vowel axis the word lives in. Once you see the register, the pattern becomes legible.
