Interjections and Sound Words

Interjections (citoslovce) are the little words that leak straight out of a feeling — the ouch, the yuck, the wow. Grammatically they are the freest words in the language: they don't inflect, they don't belong to a clause, and they usually stand outside the sentence entirely, set off by a comma or an exclamation mark. That freedom makes them look trivial, but they are one of the fastest ways to sound like a real person rather than a phrasebook. And here is the catch for English speakers: you cannot simply translate your English interjections. A Czech doesn't say "ouch" — they say au. A dog doesn't say "woof" — it says haf. Import the English word and you sound instantly foreign; use the Czech one and a native relaxes.

This page sorts Czech interjections into three families — emotional reactions, attention-getters, and sound words (onomatopoeia) — and then covers the one bit of real syntax they have: how a handful of them can govern a noun.

Emotional interjections — reacting out loud

These are the involuntary noises of feeling. Learn them as fixed units, exactly as spelled, because the vowels and length carry the emotion.

Pain is au or the stronger jau (both "ouch"):

Disgust is fuj ("yuck, ugh") — a sharp puff of revulsion, used for bad smells, gross food, and morally off behaviour alike:

Surprise clusters around jé, jejda, and the folksy jejdanánku — all roughly "oh! / oh my!". Jé is the everyday one:

Disbelief — the "no way!" reaction — is the fixed no ne (literally "well no", but functioning as amazed disbelief, not refusal):

Weariness or resignation is ach and especially ach jo — a sighed "oh well / sigh":

Joy or triumph is hurá ("hooray") — cheering, celebrating, or announcing good news:

Attention-getters — pointing, calling, warning

This family reaches out to another person: it opens a remark, flags danger, or hails someone across a room.

The single most important one for a learner is hele (and its imperative-flavoured twin heleď, plural heleďte). It literally comes from hledět "to look", but in speech it is a discourse opener — the way Czechs launch a remark, exactly like English "look, …" or "hey, listen, …". It is astonishingly frequent, and English speakers systematically under-use it because their textbooks never taught it.

Plain hej is a rougher "hey!" — hailing someone, sometimes with a note of complaint. Haló is the "hello?" you use on the phone or when calling into an empty room:

Pst (and š / šš) is the shushing "shh — quiet!":

And pozor is the all-purpose warning "watch out! / careful!" — see the next section, because it has real syntax.

When an interjection governs a noun: pozor na + accusative

Most interjections stand alone, grammatically inert. A small but important group, though, can take a complement — and pozor ("watch out") is the one you'll need daily. It governs na + the accusative case: "watch out for…".

Note that Czech uses na ("on/for") here where English uses "for" or nothing at all ("mind the step"). The full verb phrase is dát pozor na ("to pay attention to / watch out for"), so pozor sits somewhere between an interjection and a noun — which is exactly why it can carry a case complement when the pure feeling-words (au, fuj) cannot.

Sound words — Czech onomatopoeia

Onomatopoeia (zvukomalebná slova) imitate noises, and every language draws the imitation differently. Getting the Czech version right is a small delight and a frequent source of gentle laughter when learners get it wrong.

Impact and collision sounds: bum ("boom / bang", a big thud), prásk ("crack / snap", a whip or breaking wood), bác ("crash / smack", something falling over), and žbluňk ("plop", into water):

Motion sounds: hop ("hop / jump") and its emphatic double hop hop, plus cvak ("click", a switch or camera):

Animal noises are the classic set, and none of them match English:

Many of these sound words also spawn verbs: haf → hafat (to bark, childish), mňau → mňoukat (to meow), bác → bácnout (to bang down / fall over with a smack). For young children Czech has an entire parallel onomatopoeic vocabulary (haf-haf = the dog itself, bú = the cow), which is worth recognising even if you won't often use it.

The syntax: interjections stand outside the clause

Grammatically, the defining feature of an interjection is that it is not integrated into the sentence. It doesn't inflect, it takes no grammatical role (subject, object, and so on), and it is separated from the main clause by a comma or exclamation mark. You can delete it and the sentence remains complete:

The two exceptions to this pure standing-apart are the noun-governing type (pozor na + accusative, above) and the fact that some interjections have grown into full verbs (mňoukat, bácnout from bác). But the everyday feeling-words — au, fuj, jé, hurá — really are grammatical islands: pure signal, no structure.

Because they carry so much emotion, interjections are also intonation-driven. A short flat jé is mild "oh"; a long rising jéééé is delighted amazement. Written Czech signals this with repeated letters and exclamation marks, just as English does with "wowww!".

Common Mistakes

The classic error: reaching for your native interjection. English "ow / ouch / eww / yay" all have distinct Czech equivalents (au, fuj, hurá) that you have to swap in wholesale.

Pozor takes na + accusative ("watch out for"). English "for" tempts learners toward pro, but the fixed Czech frame is pozor na něco.

Onomatopoeia doesn't cross languages. Learn the Czech animal noises (haf, mňau, kykyryký) as fresh vocabulary — your instinct will be wrong every time.

Hele / heleď is the everyday conversational opener. It's not that poslouchej ("listen") is ungrammatical — it's just heavier and less idiomatic than the throwaway hele a native reaches for.

Key Takeaways

• Interjections don't inflect and stand outside the clause, set off by a comma or exclamation mark — pure emotional or attention signal.
• Swap English interjections wholesale: pain au/jau, disgust fuj, surprise jé/jejda, disbelief no ne, resignation ach jo, joy hurá.
• Hele / heleď is the high-frequency conversational opener ("look, hey"); using it is one of the quickest wins for sounding native. For its cousin, the all-purpose particle, see the particle no and the filler to.
• Pozor governs a noun with na + accusative ("watch out for"): Pozor na auto!
• Czech onomatopoeia — especially animal noises (haf, mňau, kykyryký) — are their own vocabulary and never match English. For how these overlap with the sounds speakers make while listening, see backchanneling.
