I already learned about Luatex's \patterns{} feature. So far I couldn't
make it do anything useful. Either my patterns don't do anything or I
got an error conflicting pattern error. I think I understand basic idea
of the pattern algorithm.

Thanks! The hyphenated.txt file looks like the basic Finnish hyphenation
is working as one would expect.

In order to understand the rules: why words or syllables ending with
vowel and "a" (ia, ua, oa) are not hyphenated like "aa-ri-a",
"lei-po-a", "lei-ju-a" etc.? There are no diphthongs ending with "a" or
"ä". This rule seems to work but not at the end of a word.

(I know that in line-breaks a single letter shouldn't be left alone.)

I would like to get those patterns to my own tex files. I tried to add
them with \patterns{} but they cause conflicts with something defined
elsewhere.

    (/usr/share/texlive/texmf-dist/tex/latex/base/size10.clo)) (./tavutus.aux)
    ! Conflicting pattern ignored.
