When you first meet the little word se, it's natural to read it as "self": myju se really does mean "I wash myself." But Czech has a large group of verbs where se (or its dative twin si) carries no such meaning at all. In bojím se "I'm afraid", nobody is fearing themselves; in směju se "I'm laughing", nobody is laughing at themselves. Here se is simply glued to the verb as a permanent part of it, exactly the way English keeps up in give up even though nothing goes upward. These are the inherent (or lexical) reflexives, and the only sane way to handle them is to learn the se or si as part of the word, never translating it on its own.
What "inherent" means
An inherent reflexive verb has no plain, non-reflexive twin with the same meaning. You cannot strip the se off bát se and get a verb *bát "to fear" — it doesn't exist. The se is part of the lexical entry, the way the dictionary lists it. Contrast that with a true reflexive like mýt se "to wash oneself", where mýt "to wash (something)" is a perfectly good independent verb and se genuinely means "myself/yourself".
| Type | Example | Does the bare verb exist? |
|---|---|---|
| True reflexive | myju se (I wash myself) | Yes — myju nádobí (I wash the dishes) |
| Inherent reflexive | bojím se (I'm afraid) | No — *bojím alone is not a verb |
The high-frequency members
These are the inherent reflexives you'll meet first and use daily. Notice that several of them govern an unexpected case — a hangover from old Czech that you simply learn verb by verb (see verb government).
| Verb | Meaning | Governs | Example object |
|---|---|---|---|
| bát se | to be afraid (of) | genitive | bát se tmy (the dark) |
| smát se | to laugh (at) | dative | smát se vtipu (a joke) |
| ptát se | to ask | genitive | ptát se učitele (the teacher) |
| dívat se | to watch / look | na + accusative | dívat se na film |
| stěžovat si | to complain (about) | na + accusative | stěžovat si na hluk |
| líbit se | to be pleasing / to like | dative (experiencer) | líbí se mi to |
| divit se | to be surprised (at) | dative | divit se tomu |
| těšit se | to look forward (to) | na + accusative | těšit se na léto |
bát se — fear, with the genitive
Bát se "to be afraid" is irregular in the present (bojím se, bojíš se, bojí se, bojíme se, bojíte se, bojí se) and it takes its object in the genitive: you are afraid of something. The se never leaves.
Bojím se tmy, vždycky nechávám rozsvícenou lampičku.
I'm afraid of the dark, I always leave a little lamp on.
Neboj se, nic se ti nestane.
Don't be afraid, nothing will happen to you.
smát se — laughing, with the dative
Smát se "to laugh" is a class III verb (směju se / směji se, směješ se, směje se…). What you laugh at stands in the dative, which surprises English speakers who expect "at + object".
Proč se směješ? Řekla jsem něco vtipného?
Why are you laughing? Did I say something funny?
Nesměj se mi, taky jsi to kdysi neuměl.
Don't laugh at me, you couldn't do it once either.
ptát se — asking, with the genitive
Ptát se "to ask (a question)" takes the genitive of the person you ask. Crucially, the se is obligatory — without it the sentence collapses.
Ptám se učitele, jestli můžeme odejít dřív.
I'm asking the teacher whether we can leave early.
Nikdo se mě na nic neptal, prostě jsem odešel.
Nobody asked me anything, I just left.
líbit se — the "liking" verb that flips the sentence
Líbit se "to please" deserves special care because it rearranges the whole sentence. To say I like it, Czech says líbí se mi to — literally "it pleases to-me". The thing you like is the grammatical subject, and you, the liker, are in the dative. So "I like you" comes out as líbíš se mi "you please me", not anything starting with "I". More on this pattern lives on the experiencer page.
Líbí se mi tvůj nový kabát, kde jsi ho koupila?
I like your new coat, where did you buy it?
Líbíš se mu, jen je moc stydlivý to říct.
He likes you, he's just too shy to say it.
dívat se and stěžovat si — watching and complaining
Dívat se "to look/watch" needs na + accusative for whatever you look at, and the se is non-negotiable. Stěžovat si uses the dative si rather than se, and complains na + accusative.
Na co se díváš? Dej mi taky kousek místa na gauči.
What are you watching? Make a bit of room for me on the couch too.
Pořád si stěžuje na šéfa, ale stejně tam zůstává.
He keeps complaining about his boss, but he stays there anyway.
Don't translate the particle — and don't lose it
Two failure modes haunt English speakers. The first is dropping the particle, because English has nothing there: bojím tmy feels complete to an English ear but is broken Czech. The second is over-translating it as a heavy "self/myself" object, producing things like *směju sebe "I laugh at myself" when you only meant "I'm laughing". The fix for both is the same mental habit: the se / si is not a pronoun you're choosing — it's part of the verb you already chose.
Common Mistakes
❌ Bojím tmy.
Incorrect — bát se always keeps its se.
✅ Bojím se tmy.
I'm afraid of the dark.
❌ Bojím se tmu.
Incorrect case — bát se governs the genitive, not the accusative.
✅ Bojím se tmy.
I'm afraid of the dark.
❌ Ptám učitele, kde je záchod.
Incorrect — ptát se cannot lose its se.
✅ Ptám se učitele, kde je záchod.
I'm asking the teacher where the toilet is.
❌ Líbím tě.
Incorrect — this isn't how 'I like you' works; the liker goes in the dative.
✅ Líbíš se mi.
I like you. (literally: you please me)
❌ Dívám televizi.
Incorrect — needs both se and the preposition na.
✅ Dívám se na televizi.
I'm watching TV.
Inherent reflexives are not a difficulty to be "solved" by a rule — they are vocabulary. Learn each one as a two-part word with its se or si attached and its governed case noted, and they stop being mysterious. The particle is part of the verb's identity, no more droppable than the up in English give up.
