Finnish Grammar

Subject pronouns: minä, sinä, hän, me, te, he. Finnish doesn't distinguish gender. Pronouns often dropped as verb endings indicate person.

Finnish words contain either back vowels (a, o, u) or front vowels (ä, ö, y). Suffixes must match: talo+ssa (in house), pöytä+ssä (on table).

Nominative is the basic form. Partitive (-a/-ä, -ta/-tä) used for partial amounts, negation, and after numbers. Essential distinction.

Genitive (-n) shows possession and is required before postpositions. Also used for the object of affirmative sentences.

The verb 'olla' (to be): olen, olet, on, olemme, olette, ovat. Negative: en ole, et ole, ei ole, etc. Essential for existence and identity.

Finnish expresses 'have' with adessive case + on: minulla on (I have), sinulla on (you have). Literally 'at me is'.

Present tense with personal endings: -n, -t, V/VV, -mme, -tte, -vat/-vät. Verb types 1-6 have different stem changes.

Type 1: -a/-ä (puhua), Type 2: -da/-dä (syödä), Type 3: -la/-lä/-na/-nä/-ra/-rä/-sta/-stä (tulla, mennä). Stem changes apply.

Negation with auxiliary 'ei' conjugated + verb stem: en puhu, et puhu, ei puhu, emme puhu, ette puhu, eivät puhu.

Inner local cases: inessive (-ssa/-ssä = in), elative (-sta/-stä = from), illative (-Vn/-hVn/-seen = into).

Outer local cases: adessive (-lla/-llä = on/at), ablative (-lta/-ltä = from), allative (-lle = to/onto).

Cardinal numbers 0-100, telling time (kello on), days of the week, months. Numbers 2+ take partitive of the counted noun.

Adjectives agree with noun in number and case: iso talo (big house), isossa talossa (in a big house). Predicative adjectives don't decline for case.
