Vyjmenovaná slova — literally "listed words" or "enumerated words" — are the heart of Czech spelling and the thing every Czech child spends years drilling. They are closed, fixed lists of root words that take a hard y after the ambiguous consonants b, f, l, m, p, s, v, z. The reason they exist is the cleanest illustration of the whole i/y problem: after these eight consonants the sound i and the sound y are identical, so nothing in the pronunciation tells you which letter to write. Czech solves this not with a rule you can reason out, but with a list you memorise. Every word on the list takes y; every other word with that consonant takes i.
Why a list, and not a rule
Recall the three-zone system from the i/y overview. After soft consonants you always write i; after hard consonants you always write y; both of those are automatic (see automatic i/y). The eight ambiguous (obojetné) consonants — b, f, l, m, p, s, v, z — sit in the middle: historically some words after them had a y and some had an i, the two sounds later merged, and the spelling froze. Modern Czech preserves the old distinction by simply listing the y-words. So the question "i or y after a b?" has no phonetic answer — only "is this word on the b-list?"
Odjakživa bydlíme na kraji města.
We've always lived on the edge of town. (bydlet is on the b-list → y)
To víno bylo opravdu výborné.
That wine was really excellent. (víno is NOT listed → i; výborné is built on a v-list root → y)
Derived words inherit the y
A list of bare roots would be nearly useless on its own, so the rule comes with a powerful extension: words built from a listed root keep the y. Once bydlet (to live, reside) is on the b-list, its whole family follows — bydliště (residence), obydlí (dwelling), bydlení (housing), bydlo (livelihood). You learn one root and get a dozen relatives for free. The flip side is that you must recognise the root inside a longer word, even when a prefix hides it.
Trvalé bydliště mám v Brně.
My permanent residence is in Brno. (bydliště, from bydlet → y)
Celé obydlí bylo zasypané sněhem.
The whole dwelling was buried in snow. (obydlí, from bydlet → y)
Nakoupili jsme nový nábytek do obýváku.
We bought new furniture for the living room. (nábytek and obývák both trace to the b-list → y)
A look at the b-list
To make this concrete, here is the traditional b-list — the vyjmenovaná slova po b that Czech children recite in order. It is short, finite, and famous:
být, bydlit, obyvatel, byt, příbytek, nábytek, dobytek, obyčej, bystrý, bylina, kobyla, býk, Přibyslav
| Listed word | Meaning | Some derived words (also y) |
|---|---|---|
| být | to be | bytí, bývat, zbytek |
| bydlit / bydlet | to live, reside | bydliště, obydlí, bydlení |
| obyvatel | inhabitant | obyvatelstvo, obyvatelný |
| byt | flat, apartment | bytný, bytový |
| nábytek | furniture | nábytkový |
| dobytek | cattle, livestock | dobytče |
| bylina | herb, plant | bylinka, bylinný |
| kobyla | mare | kobylka (also "grasshopper") |
| býk | bull | býček |
The remaining items — příbytek (abode), obyčej (custom; cf. obyčejný = ordinary), bystrý (sharp-witted), and the place name Přibyslav — round out the b-list. The other ambiguous consonants have their own lists, covered on the b, l, m page and the p, s, v, z page. (The consonant f is a special case: native Czech has essentially no f-words, so there are no vyjmenovaná slova after f worth learning.)
Hledáme menší byt blízko centra.
We're looking for a smaller flat near the centre. (byt → y)
Babička pěstuje na zahradě léčivé byliny.
Grandma grows medicinal herbs in the garden. (byliny, from bylina → y)
Sedlák se ráno stará o dobytek.
The farmer tends the cattle in the morning. (dobytek → y)
Membership decides homophones
The most consequential job the lists do is settling homophones — pairs that sound exactly alike and split only on i/y. The decision is nothing but list membership:
| On the list → y | Not on the list → i |
|---|---|
| být (to be) | bít (to beat, hit) |
| mýt (to wash) | mít (to have) |
| výr (eagle owl) | vír (whirlpool) |
Chci tady prostě v klidu být.
I just want to be here in peace. (být = to be, on the list → y)
Není slušné nikoho bít.
It's not decent to hit anyone. (bít = to hit, not listed → i)
Půjdu si umýt ruce, mám je špinavé.
I'll go wash my hands, they're dirty. (umýt, from mýt → y)
Write bít where you mean být and you haven't made a slip of the pen — you've written "to beat" where you meant "to be." That is why these lists, dry as they look, carry real meaning.
Common mistakes
❌ Hoping for a rule to derive y after b/l/m/p/s/v/z.
Incorrect expectation — there is no derivable rule; the vyjmenovaná slova are a memorised list.
✅ Learn the lists; everything off the list takes i.
Correct — membership is the only criterion after the ambiguous consonants.
❌ Writing 'bidlet' for 'to live/reside'.
Incorrect — bydlet is on the b-list, so it takes y: bydlet, bydliště, obydlí.
✅ bydlet, bydliště, obydlí
to live, residence, dwelling (all y, from the listed root)
❌ Writing 'mýt' when you mean 'to have'.
Incorrect — 'to have' is mít (i); mýt (y) means 'to wash'. Only mýt is on the m-list.
✅ mít = to have; mýt = to wash
Correct — the i/y choice splits two different verbs.
❌ Missing the listed root inside a longer word ('nabitek').
Incorrect — nábytek contains a b-list root, so it keeps y: nábytek.
✅ nábytek, příbytek, obyvatel
furniture, abode, inhabitant (derived/related forms keep y)
Key takeaways
- Vyjmenovaná slova are closed lists of root words that take y after the ambiguous consonants b, f, l, m, p, s, v, z; every other word after those consonants takes i.
- They exist because i and y sound identical after these consonants — there's no rule, only a memorised inventory.
- Derived words inherit the y (bydlet → bydliště, obydlí), so learn the root and recognise it inside longer words.
- The b-list is the famous starter chant: být, bydlit, obyvatel, byt, příbytek, nábytek, dobytek, obyčej, bystrý, bylina, kobyla, býk, Přibyslav.
- Membership settles homophones: být/bít, mýt/mít, výr/vír differ only in i/y — and in meaning.
