Tehdä Conjugation

tehdä means "to do / make" in Finnish. Present: minä teen, sinä teet, hän tekee, me teemme, te teette, he tekevät. Below: all 46 tenses we teach, with examples.

Present Preesens

Weak-grade stem + personal endings (-n, -t, vowel lengthening, -mme, -tte, -vat/-vät). It also covers the future, because Finnish has no separate future tense; context and time words (huomenna, ensi viikolla) show it.

Imperfect (Simple Past) Imperfekti

Past stem in -i- + endings. It is the normal narrative past and also answers 'did you ...?'. Gradation often returns the strong grade in the 3rd person (luin but luki).

Perfect Perfekti

Present of olla + past active participle (-nut/-nyt; plural -neet). Used for results and experience up to now, as in English, often with jo (already) or koskaan (ever).

Pluperfect Pluskvamperfekti

Imperfect of olla + past active participle. Used for something finished before another past moment.

Present (Negative) Preesens, kielteinen

The negative verb (en, et, ei, emme, ette, eivät) + the bare present stem (connegative, weak grade, no personal ending). The negative verb carries person; the main verb never changes.

Imperfect (Negative) Imperfekti, kielteinen

Negative verb + past active participle (singular -nut, plural -neet). The participle agrees in number with the subject, not the person.

Perfect (Negative) Perfekti, kielteinen

Negative verb + ole + past active participle.

Pluperfect (Negative) Pluskvamperfekti, kielteinen

Negative verb + ollut/olleet + past active participle.

Present Passiivin preesens

Passive stem + -ttiin/-tiin (-ttiin after strong stems).

Perfect Passiivin perfekti

on + past passive participle (-ttu/-tu).
