Partitive formation varies for example

lupaus (nom.) > lupauksen (gen.) lupausta (ptv.)

abstract noun lupaus permission is derived from luvata (to permit)
verb stem lupaa- + -us (abstract noun formation) > laupaus (with standard dropping of the extra vowel)

kaipaus (nom.) > kaipauksen (gen.) kaipausta (ptv.)

abstract noun kaipaus longing or yearning is derived from kaivata (to yearn

for, long for, to miss)

verb stem kaipaa- +-us (abstract noun formation) > kaipaus (with standard dropping of the extra vowel)

lisäys (nom.) > lisäystä (ptv.)

abstract noun lisäys addition or increase is derived from lisätä ('to increase. add to)
verb stem lisää- + -us (abstract nounn formation) > lisäys (with standard dropping of the extra vowel)

lykkäys (nom.) > lykkäystä (ptv.)

abstract noun lykkäys postponement is derived from lykätä to postpone
stem lykkää- become (abstract noun, postponement)


The group that forms differently are usually formed from nouns and adjectives. These forms have genitive forms where the s transforms to d but partitive forms where the s transforms to t.

vapaus (nom.) freedom > vapautta

rakkaus becomes rakkautta

onnettomuus becomes onnettomuutta

ystävyys becomes ystävyyttä

kateus becomes kateuta

pimeys becomes pimeyttä

The rule is that if the word is derived from a nominal form, then the partitive will take the standard -ta or -tä ending which usually attached to nominals ending in a consonant. BUT, if the word is derived from an adjective (which may itself be derived from a verb) the s usually mutates to to a t before the -ta or -tä ending ius added.
