Text: A Text Message Exchange

Textbooks teach you the standard written language; your Czech friends will text you in something quite different. Real informal chat is full of obecná čeština (Common Czech) creeping into writing, dropped diacritics, clipped greetings, and tiny particles that do a lot of work. This page takes a short, completely ordinary exchange between two friends and reads it line by line, so you can see exactly where casual written Czech diverges from the standard — and why. None of it is "wrong"; it is simply the register of friends arranging to meet for a beer.

The exchange

— Čau, děláš dneska něco? — Néé, sem doma. Nechceš zajít na pivo? — Jasně, dík!

Three short lines. Underneath them sit at least six features that no textbook dialogue would show you. Let's walk through each turn.

Line 1: Čau, děláš dneska něco?

Čau is the all-purpose informal hello and goodbye, borrowed long ago from Italian ciao and now thoroughly Czech. You will also see it spelled Cau in texts, with the diacritic dropped — a habit we'll come back to. Use it only with people you'd address as ty; with a stranger or in an email you'd write Dobrý den.

děláš is the second-person singular of dělat ("to do, to make"), imperfective. The imperfective is right here because the question is about an ongoing or general state of affairs — "have you got anything on" — not a single completed act.

dneska is the conversational form of dnes ("today"). Both mean exactly the same thing, but dnes sounds slightly bookish in casual speech, while dneska (with the extra -ka) is what people actually say and text. The same -ka shows up in teďka (teď, "now") and tamhleta — it is a colloquial flavouring suffix.

Line 2a: Néé, sem doma.

Néé is ne ("no") with the vowel dragged out and the spelling stretched to match — a written rendering of intonation, the way English writes "naaah" or "nope." This is pure chat orthography: you would never see néé in print, but in a text it conveys a relaxed, drawn-out "no."

sem is the single most characteristic feature of the whole exchange. It is jsem ("I am") with the initial j- dropped. In standard written Czech you must write jsem; but in real speech the j- in front of s is almost always silent, and casual writing simply records what the mouth does. The same happens across the auxiliary: jsi → seš, jsme → sme, jste → ste.

Notice too that the subject pronoun já ("I") is dropped entirely — the -m ending of sem already tells you who is at home. Czech is pro-drop, and conversation drops even more than the standard does.

Line 2b: Nechceš zajít na pivo?

This is the social heart of the message, and two things are happening.

First, the negated question as a friendly offer. Nechceš…? literally means "don't you want…?", but Czech (like English "Wouldn't you like…?") uses the negative form to make an invitation warmer and less pushy than the bald Chceš…? ("Do you want…?"). The negation presumes a yes and softens the ask.

Second, and grammatically the richest point: zajít is a perfective verb, and the choice matters. It is built from jít ("to go") plus the prefix za-, which here adds the sense of "drop by / pop in for a short while." So zajít na pivo frames the outing as a single, bounded, quick event — nip out, have a beer, done. Contrast the imperfective motion verb chodit ("to go regularly, to frequent"): chodit na pivo would mean "to go (habitually) for beers," a recurring habit, not tonight's plan.

The na + accusative in na pivo ("for a beer") is the standard pattern for going somewhere for the purpose of something: jít na pivo, jít na kávu, jít na oběd ("go for lunch"). Here pivo is in the accusative (identical to its nominative, since it's neuter).

Line 3: Jasně, dík!

Jasně literally means "clearly," but as a standalone reply it is the colloquial "sure / of course / you bet" — an enthusiastic yes. It is a particle of agreement, doing the same job as English "Sure!" Other agreement particles you'll see in chat: jasan (even more casual), no jasně ("yeah for sure"), and plain jo (the colloquial "yeah," versus standard ano).

dík is the clipped, breezy "thanks," a shortened díky, which is itself the casual cousin of the fuller děkuji ("thank you"). The register ladder runs: děkuji (neutral/polite) → díky (friendly) → dík (very casual, chatty). In a text to a friend, dík is perfect; to your landlord you'd write děkuji.

The diacritic-light texting habit

Across the whole exchange, you may see the diacritics quietly disappear when people type fast — Cau for Čau, delas for děláš, neco for něco. Czech phones handle háček and čárka fine, but many people drop them in casual chat for speed, and readers fill them back in from context with no trouble. This is purely a texting convention: it would be a spelling error anywhere formal.
