Zompist Bboard Again

In native words, how common are the following consonant clusters in roots, not across morpheme boundaries?

• pl pr tr tv kl kr
• sh sm sn sl sj
• hs hl
• mh
• lh ln

Do you mean across syllable boundaries? I would say something like this:

Less unusual: hl (mahla, pihlaja, kahlata, tuhlata), lh (ylhäällä, alhaalla, kulho, valhe)
Very unusual: tv (latva, Ritva), tr (Kultakutri, mutrusuu), sm (horsma, Sysmä), sl (kaisla)
Not in native words: pl, pr, kl, kr, sh, sn, sj, hs, mh, ln

What is this for?

That's great, thanks. It's for enlightenment purposes.

Hmm, intriguing.
