Usage notes
- When talking about where something is established or founded ("in", "at"), the illative or allative cases are generally used. The inessive or adessive cases may also be used, but have a different nuance; the former focuses more on the act of establishing or founding, while the latter implies the place is less relevant or broader.

1) Used only with a possessive suffix.
2) Usually with a possessive suffix (active only).
3) Some uses of the verbal noun are called the 'fourth infinitive' by certain sources (more details).
4) Usually with a possessive suffix. May not be used with all verbs, especially intransitive ones (more details). Distinct from nouns with the -ma suffix and third infinitive forms.
* The third-person singular indicative form perustaa does not exhibit final gemination, unlike the first infinitive (the lemma form), even though they are spelled identically. |
