Finnish as a Second Language cheat sheet

Finnish is written with spaces between words and no grammatical gender; the difficulty lies in case endings and consonant gradation, not in word division.

Agglutination means a single long word can carry stem + number + case + possessive: talo·ssa·ni = 'in my house'; split the word from the right to find the case.

The partitive (-a/-ä, -ta/-tä, -tta/-ttä) marks incomplete quantity, mass nouns, negation objects and ongoing action: luen kirjaa = 'I am reading a book'.

Object case rule: a completed, whole object takes the total object (genitive -n or nominative plural -t); a partial or interrupted object takes the partitive.

Consonant gradation changes k, p, t between strong and weak grades when a syllable closes: kauppa → kaupan, katu → kadun, kylpy → kylvyn.

Text-type cues: news items front-load the main clause; official letters place the decisive sentence (deadline, consequence) in the final paragraph.

Reference chains use hän (people), se (things and, colloquially, people), ne (plural); track the referent, not the literal pronoun.

Numbers and dates are written with a comma decimal (3,5) and a period in dates (3.5.2025 = 3 May 2025); a colon separates the year from the suffix (2025: ssä).

Spoken Finnish drops final vowels and shortens forms: minä → mä, sinä → sä, tämä → tää, tule → tuu; recognise the standard form behind the colloquial one.

The passive is used for 'we' in speech: me mennään = 'we go', me ollaan = 'we are'; it is not a true passive in meaning.

Puhekieli uses se for hän and ne for he, so person is carried by the verb ending and context rather than the pronoun.

Question particles rise in pitch: -ko/-kö yes/no questions and the question word (mikä, missä, milloin) carries the main stress.

Numbers, prices and times are the highest-risk items; write them down as digits while listening rather than holding them in memory.

Common reduced forms: ymmärrä → ymmärrä/ymmärrät, mutta → mut, että → et(tei), kaikki → kaikk(i); the dropped sound is rarely meaningful.

Negation in speech: en, et, ei, emme → me ei; the negative verb is followed by the verb stem (en tule, ei tule).

Discourse markers signal structure: no ('well'), niin ('so'), siis ('thus'), elikkä ('that is'), and tota ('um') usually mark a hesitation, not content.

Formal written Finnish avoids puhekieli: use minä, sinä, hän, emme, and full verb forms; contractions such as mä or sä belong to informal messages.

Sentence-initial capital and full stops are standard; the comma separates clauses and lists, and the decimal comma (3,5) is obligatory.

Object and predicate agreement: a total object in the plural takes -t and the predicate agrees in number (Kirjat ovat pöydällä).

The partitive is required after numbers greater than one (kaksi kirjaa), after mass expressions (vähän vettä) and in negative clauses (en osta autoa).

Postpositions govern the genitive (pöydän alla, talon edessä); prepositions are few (ilman sinua, ennen joulua).

Text cohesion uses reference (se, tämä), conjunction (mutta, koska, vaikka) and lexical repetition; avoid starting every sentence with the subject.

Register markers: -kin ('also'), -kaan/-kään ('not either'), -han/-hän ('after all'), -pa/-pä (emphasis); one per clause is the norm.

Formal letter frame: Otsikko/aihe, greeting (Hyvä vastaanottaja), body, closing (Ystävällisin terveisin) and signature.

Vowel length and consonant length are phonemic: tuli ('fire'), tulli ('customs'), tuuli ('wind'); hold long sounds about twice as long as short ones.

Primary stress is always on the first syllable; secondary stress falls on later odd syllables, so stress is predictable from spelling.

Question intonation rises at the end for yes/no questions and falls for wh-questions; statement intonation falls.

Filler and repair strategies: niin, siis, miten sen sanoisin ('how should I say it'), and self-repair by restating with a simpler verb.

Turn-taking cues: niin ('yeah'), joo, aivan, exactly; a short back-channel does not mean agreement, only that the listener follows.

Politeness is carried by the conditional and the particle -han/-hän: Voisitko…? ('Could you…?'), rather than by a separate word for 'please'.

The negative verb is inflected for person (en, et, ei, emme, ette, eivät) and the main verb stays in the stem: en mene.

Colloquial speech is expected in informal talk, but a formal situation (interview, office) calls for kirjakieli-like forms; match the register of the interlocutor.

Six local cases form a system: inessive -ssa/-ssä, elative -sta/-stä, illative -Vn/-hVn/-seen, adessive -lla/-llä, ablative -lta/-ltä, allative -lle.

Case choice encodes direction: missä (in), mistä (from inside), mihin (into); millä (on), miltä (from off), mille (onto).

Verb types govern the infinitive: type 1 (puhua → puhun), type 2 (tehdä → teen), type 3 (tulla → tulen), type 4 (haluta → haluan), type 5 (valita → valitsen), type 6 (vanheta → vanhenen).

Past tense: -i- marks the imperfect (puhuin, tulimme); the perfect uses olla + past participle (olen puhunut) and the pluperfect olin puhunut.

Possessive suffixes attach after the case ending: talossani, taloistani; the genitive stem is the base for most suffixes.

Derivation changes meaning predictably: -ja/-jä (agent: opettaja), -minen (action noun), -llinen (having: onnellinen), -ton/-tön (without: työtön).

Comparative and superlative: iso → isompi → isoin; the partitive plural is the comparative stem (isompia).

Vocabulary traps: 'to remember' is muistaa, 'to forget' unohtaa; 'to like' pitää + elative (pidän kahvista), not a direct object.

Sinuttelu (first-name, sinä) is the default in workplaces, shops and among students; teitittely (te) is reserved for elderly or very formal service situations.

Finnish silence is a turn-taking signal, not disagreement; a pause of several seconds before answering is normal and should not be filled.

Small talk is limited; topics such as salary, religion and personal health are avoided with strangers, while weather and travel are safe.

Punctuality is a hard norm: arriving at the agreed time, not early or late, is expected in meetings and appointments.

The sauna is a social institution; declining an invitation is acceptable, and mixed-gender sauna happens mainly within families.

Everyday services are increasingly digital; strong authentication (verkkopankki) is the standard route to public services, which affects how 'communication' is practised.

Repair strategies: ask for repetition (Anteeksi, voisitko toistaa?), for slower speech (Voitko puhua hitaammin?) or for a paraphrase (Mitä se tarkoittaa?).

Indirect refusal is common: 'no' may appear as Kyllä se varmaan käy, mutta… ('It probably works, but…'); listen for the mutta-clause.
