The single most important Finnish verb is olla, to be. Each person has its own form:

Pronoun	Olla	English
minä	olen	I am
sinä	olet	you are
hän	on	he / she is
me	olemme	we are
te	olette	you are (two or more)
he	ovat	they are

The ending tells you who is meant — so clearly that Finns usually drop minä, sinä, me and te: Olen Marina. — I'm Marina. Olemme Helsingissä. — We're in Helsinki.

Hän and he stay: Hän on Luana. — She's Luana. (On Luana on its own would be incomplete.)
