dovést and dokázat — Manage, Be Capable Of

English has only one word, can, for a whole range of meanings: a learned skill ("I can swim"), a permission or circumstance ("I can come tomorrow"), and an achievement reached through effort ("I managed to finish it"). Czech beginners learn umět vs moci vs znát for the first two. This page adds the pair that carries the third, achievement-flavoured sense: dovést and dokázat. Both translate loosely as "to be able to / to manage to / to be capable of," but they sit a notch above plain umět and moci — they imply that the ability is real enough to produce a result, not just a textbook competence or a free slot in the calendar.

The quick answer

• umět — a learned skill. Umím vařit. (I can cook — I've learned how.)
• moci / moct — you are in a position to act: circumstances, permission. Můžu přijít. (I can come.)
• dovést — you are capable of something, you have it in you; leans toward disposition and capacity. Dovede být milý. (He can be nice — he's capable of it.)
• dokázat — you managed it, you pulled it off; a single achievement reached through effort. Dokázal to. (He managed it / He pulled it off.)

dokázat — to manage, to pull off (achievement)

Dokázat is perfective. Like all perfectives it describes a single, bounded, completed event — here, an achievement. When you say Dokázal to, you are not describing a standing ability; you are reporting that on this occasion, against some difficulty, the thing actually got done. English reaches for managed to, succeeded in, or pulled off.

Because dokázat is perfective, its present-tense forms (dokážu, dokážeš, dokáže…) carry future meaning, like any perfective present. Dokážu to means "I'll manage it / I'll pull it off," not "I am managing it." This is the imperfective–perfective machinery at work: there is an imperfective partner dokazovat, but in the "manage" sense the perfective dokázat is overwhelmingly the form you want.

The "I can't imagine" trap

One construction with dokázat is so common — and so reliably mistranslated by English speakers — that it deserves its own warning. To say "I can't imagine (it)", Czech does not use nemůžu; it uses nedokážu si představit. The reflexive si (dative "to/for myself") is part of the idiom.

Saying nemůžu si představit sounds wrong to Czech ears here, because the issue is not permission or circumstance (moci) — it is whether your mind is capable of producing the image. That is exactly the capacity sense that dokázat owns.

dovést — to be capable of, to have it in one

Dovést also means "to be able to / be capable of", but it leans toward disposition and capacity rather than a one-off achievement. It tells you what a person has in them — what they are capable of doing, for better or worse. It is morphologically the perfective of vést "to lead" frozen into a modal-like verb; despite its perfective shape it behaves as a stable capability verb and is conjugated in the present (dovedu, dovedeš, dovede, dovedeme, dovedete, dovedou).

The flavour of dovést is "is capable of this, has the capacity". Dovede být milý does not mean he is nice now or that he learned niceness in a course — it means niceness is within his range. This is why dovést shades naturally into describing temperament, talent, and tendency.

dovést si poradit, dovést si pomoct

Two fixed reflexive phrases with dovést are everyday and worth memorising as units: dovést si poradit "to be able to cope / manage / sort oneself out" and the negative nedovést si pomoct "to not be able to help oneself."

dovést vs dokázat side by side

The two overlap heavily, and in many sentences either is acceptable. The reliable distinction is standing capacity (dovést) versus a completed achievement (dokázat).

The first reports a capacity (dovede); the second reports that on a specific, effortful occasion the work got done (dokázal). When you want "has it in him," reach for dovést; when you want "got it done despite difficulty," reach for dokázat.

dokázat also means "to prove"

A genuine ambush for learners: outside the modal sense, dokázat + accusative object means "to prove / demonstrate" — as in proving a point, a theorem, or a fact. Here it is an ordinary transitive verb with an accusative object, not a verb of capability followed by an infinitive, so context and what follows the verb tell the two senses apart.

The split is easy once you notice the pattern: dokázat + infinitive = "manage to (do)", dokázat + noun in the accusative = "prove (a thing)". Dokázal odejít "he managed to leave"; Dokázal teorém "he proved the theorem."

How all four "can" verbs divide the work

A single scene shows the labour neatly divided:

• umím řídit — a learned skill (umět).
• nemůžu — today's circumstances forbid it (moci).
• nedokázal bych vydržet — I wouldn't have it in me to endure it (dokázat, here in the conditional).

For the basic three-way split, see umět vs moci vs znát; for the full four-way knowing/being-able picture, see moci / umět / znát / vědět.

Common Mistakes

Key Takeaways

• dokázat (perfective) = manage to / pull off / succeed in — a single achievement reached through effort: Dokázali jsme to.
• dovést = be capable of / have it in you — a standing capacity or disposition, used in present forms: Dovede být milý.
• "I can't imagine" is nedokážu si představit, never nemůžu si představit.
• Because dokázat is perfective, dokážu to means "I'll pull it off" (future), not "I'm managing it."
• dokázat + accusative is a second verb entirely: "to prove" (dokázat teorém "prove a theorem").
• These two sit above plain umět (learned skill) and moci (circumstance/permission): they add capacity and achievement.
