From Proto-Finnic *-ttu, from *-tta- (passive infix) + an uncertain suffix, probably either *-u or *-ut (compare *-nut).
- IPA(key): /-tːu(ˣ)/, [-t̪ːu(ʔ)]
-ttu (front vowel harmony variant -tty, linguistic notation -ttU)
- Forms the past passive participle of a verb, which is normally used like an adjective. The English equivalent is normally -ed.
- katsoa (“to see, look, watch”) + -ttu → katsottu (“(that has been) seen, watched”)
- Some inflected forms have specific uses:
- genitive singular: used with verbs of reporting or observing to refer to the action having been done by someone (passively) according to that report or observation.
- Artikkelia sanotaan luetun paljon Suomen kouluissa. ― It is said that this article has been read a lot in Finnish schools.
- partitive singular:
- used (chiefly) with a possessive suffix for "having done", "after X had done"
- Syötyäni päätin ottaa nokoset. ― Having eaten, I decided to take a nap.
- used with saada to express finishing something, often in the sense of an achievement
- Sain sen syötyä. ― I managed to eat it.
- used with tulla without a possessive suffix to disparagingly talk about something someone has done
- Mitä tuli sanottua? ― What did you (just) say (to me)?
