Text: A Recipe

A recipe is one of the most aspect-rich texts in any language, and in Czech it quietly does something English simply cannot: it grades every instruction for aspect. Some steps are bounded one-and-done actions; others are processes you sustain. Czech marks the difference on the verb, step by step, and a fluent reader feels the rhythm of the cooking from the verb forms alone. This page reads two short lines of a recipe and pulls out the imperative, the aspect contrast, a clitic pronoun, and a numeral phrase.

The text

Nakrájejte cibuli, osmažte ji na másle a postupně míchejte. Vařte deset minut.

Naturally translated: "Chop the onion, fry it in butter and keep stirring. Boil for ten minutes."

Word by word

• Nakrájejte — perfective imperative, 2nd person plural, of nakrájet "to chop up, cut up (completely)." The na- prefix makes it perfective: this is one bounded action — get the onion chopped, full stop. The -te ending is the plural/polite imperative.
• cibuli — accusative singular of cibule "onion," a soft feminine noun in -e, which shifts to -i in the accusative: cibule → cibuli. It's the direct object of nakrájejte.
• osmažte — perfective imperative, 2nd plural, of osmažit "to fry through, sauté (until done)." Again the prefix (o-) signals a completed result — fry it and finish frying it.
• ji — the accusative clitic pronoun "her / it," standing in for cibuli (feminine). It's a second-position clitic. Mind the spelling: ji (short i) is accusative; jí (long í) would be dative/instrumental.
• na másle — na
  • the locative of máslo "butter" → na másle, "in/on butter." Locative because nothing is moving; the frying happens at the butter, a static location.
• a — "and."
• postupně — adverb "gradually, bit by bit, as you go."
• míchejte — imperfective imperative, 2nd plural, of míchat "to stir, mix." No prefix, plain imperfective: this is an ongoing process — keep stirring, repeatedly, for as long as it takes.
• Vařte — imperfective imperative, 2nd plural, of vařit "to boil, cook." Another sustained process: keep it boiling.
• deset minut — "ten minutes." deset "ten" governs the genitive plural minut (the zero-ending genitive plural of minuta), and the whole phrase is an accusative of duration answering jak dlouho? "how long?"

Grammar in action

Why some steps are perfective and others imperfective

This is the heart of the text, and the single most useful thing a recipe can teach you. Look at how the four verbs split:

The logic is consistent across every Czech recipe you'll ever read. A step that reaches a result and stops — chop the onion, fry it through, pour in the stock, add salt — takes the perfective. A step you sustain over time — stir, boil, simmer, beat — takes the imperfective. The cook can almost read the dish off the verbs: perfectives are discrete moves, imperfectives are the stretches in between.

English cannot mark this. "Chop the onion, fry it, stir, boil" gives every verb the same bare imperative; the difference between a one-off action and a sustained one lives only in the reader's intuition. Czech makes it grammatical. That's why a learner who keeps everything imperfective — krájejte, smažte, míchejte, vařte — produces a recipe that sounds oddly tentative, as if the cook should keep chopping the same onion forever.

In the first, přidejte (add — done) and promíchejte (stir until combined — a bounded result) are both perfective. In the second, míchejte is imperfective because the stirring continues until a condition is met. The full treatment is on the aspect in the imperative page, and the underlying perfective-vs-imperfective decision is on choosing perfective or imperfective.

There's a twist worth flagging: in negative commands the pattern often flips, and the imperfective becomes the default. Nesolte to "don't salt it" is imperfective; the perfective nepřesolte to "don't over-salt it!" survives only as a warning against a single accidental ruin. That asymmetry has its own page, aspect in affirmative vs negative imperatives.

The plural imperative: who is the recipe talking to?

Every verb here ends in -te: nakrájej-te, osmaž-te, míchej-te, vař-te. That's the plural / polite imperative, and Czech recipes use it as a default register — they address you, the cook, as Vy. The singular forms (nakrájej, osmaž, míchej, vař) would feel like a parent talking to a child and are rare in print.

You'll also meet older or more impersonal cookbooks that use the bare infinitive as an instruction (Cibuli nakrájet, osmažit na másle…), which reads like a terse checklist. The plural imperative is the friendly modern standard.

The clitic ji, and na + locative

Osmažte ji uses ji, the accusative pronoun "it," to avoid repeating cibuli. It's a clitic, so it leans on the verb and wants second position in its clause. Keep the vowel length straight: ji (accusative) versus jí (dative/instrumental) is a real minimal pair that spell-checkers won't always catch.

Na másle shows na + the locative, because frying is a static "at this location" situation, not movement. Contrast na pánev (onto the pan — accusative, direction) with na pánvi (on the pan — locative, location); butter you fry in is na másle.

deset minut — counting and duration at once

Vařte deset minut does two grammatical jobs in two words. First, the numeral: five and above governs the genitive plural, so deset takes minut (the bare-stem genitive plural of minuta) — compare dvě minuty (2–4 → nominative plural) with pět minut, deset minut (5+ → genitive plural). Second, the phrase has no preposition: a stretch of time answering "how long?" goes into the bare accusative of duration. English needs "for"; Czech just puts the time in the accusative.

The numeral-plus-genitive rule is detailed on five and up take the genitive plural, and the no-preposition duration pattern on the accusative of duration.

Usage and culture note

Czech home cooking runs on butter, onion, and patience, and the recipe register is remarkably stable: plural imperatives, aspect graded step by step, temperatures in degrees Celsius (na 180 stupních), and quantities often by feel (špetka soli "a pinch of salt," trochu "a little"). When you write your own instructions, the giveaway of a native-sounding text isn't vocabulary — it's getting the aspect right on every verb. A recipe that says nakrájejte and vařte in the right places reads as effortless; one that mixes them up reads as translated.

Common Mistakes

Key Takeaways

• Recipes grade every step for aspect: perfective for bounded one-off actions (nakrájejte, osmažte), imperfective for sustained processes (míchejte, vařte).
• Czech recipes default to the plural / polite imperative in -te, addressing the cook as Vy; older texts may use the bare infinitive.
• The clitic ji (accusative "it") sits in second position; watch the ji vs jí length distinction.
• na másle is na + locative because frying is static; movement onto a surface would be na
  • accusative.
• deset minut combines two rules: 5+ governs the genitive plural (minut) and duration takes the bare accusative (no "for").
