Tarvita ("to need") is the essential Type 5 verb, and Type 5 is the one class where the dictionary form actively lies to you. The infinitive ends in -ita, but the moment you conjugate, a hidden -tse- appears: tarvita → tarvitsen. You cannot guess this from the infinitive — it is the defining signature of the class, and its twin valita ("to choose") behaves identically (valita → valitsen). Learn tarvita well and every Type 5 verb falls into place. The model of the class is tarvita itself.
Principal parts
| Infinitive | Present 1sg | Present 3sg | Past 1sg | Past participle |
|---|---|---|---|---|
| tarvita | tarvitsen | tarvitsee | tarvitsin | tarvinnut |
Two things to fix in memory. First, the present stem is tarvitse-, not tarvi-: you conjugate tarvitsen, tarvitset…. Second, the past participle tarvinnut drops the -tse- entirely — it is built on the consonant stem tarvit- (tarvit- + -nut → tarvinnut), so it is emphatically not *tarvitsenut.

Conditional, imperative, passive

The passive builds on the consonant stem tarvit-: present tarvitaan, past tarvittiin, perfect on tarvittu, past passive participle tarvittu. The negative leaves the connegative tarvitse (present) or tarvinnut / tarvinneet (past): en tarvitse, emme tarvinneet.

Object aspect: what you need
Tarvita governs an aspectual object. The partitive is the default — it fits mass nouns and open-ended needs (tarvitsen rahaa "I need [some] money"). The total accusative appears when the need is a specific, bounded whole you mean to obtain (tarvitsen sen avaimen "I need that key").

ei tarvitse — "don't have to"
Negated, tarvita joins the necessity verbs (täytyä, pitää): it takes a genitive subject and a following infinitive, and ei tarvitse means "there is no need to / doesn't have to" — a gentle relief, not a prohibition.
