Finnish also has the following sets of diphthongs. All other diphthongs are sequences of vowels belonging to separate syllables. As I noted above, syllables in Finnish can only have simple onsets, but may have complex codas. An intervocalic consonant belongs to the following syllable while the second element of a geminate also forms an onset. Stress Primary stress in Finnish falls on the initial syllable.
Secondary stresses fall on every other syllable except the final.
However, if the third syllable of a word of five or more syllables is short, the fourth syllable is assigned secondary stress. Finnish appears to have top-down initial stress. That is, primary stress is assigned first. In the latter, secondary stress is probably assigned to the third syllable to avoid both word-final stress and a degenerate foot although it violates weak local parsing. Metrical Stress Theory.
