In standard Polish, the digraph ch and the single letter h spell exactly the same sound: a voiceless velar fricative , the throaty rasp of Scottish loch or German Bach. They are homophones on the page. Nothing in the pronunciation tells you which one to write, so — just like English to/too/two — you have to know the word. This page gives you the morphological and historical rules that decide between them, plus the short list of h words worth memorising, since h is the rare exception and ch is the overwhelming default.
They sound the same — that's the whole problem
For most English-speakers this is the first surprise: there is no audible difference. The pair hart (greyhound) and chart would be pronounced identically — both [xart] — were chart a word. English has no single letter for the sound at all (we lost it; it survives only as the silent gh in night, through), so the instinct to "sound it out" gives you nothing here.
Mam ochotę na herbatę.
I feel like having tea.
In that one short sentence, ochotę spells the sound with ch and herbatę spells it with h — same sound, two spellings, decided purely by the history of each word.
Chleb i ser, nic więcej nie trzeba.
Bread and cheese, nothing else is needed.
When to write ch
Rule 1 — ch alternates with sz. This is the single most reliable test. If a related form of the word has sz where the sound sits, you write ch. The two are historical variants of the same root: softens to [ʂ] (written sz) under palatalisation.
| ch-word | Related form with sz | Meaning |
|---|---|---|
| mucha | muszka | fly → little fly |
| słuchać | słyszeć | to listen → to hear |
| ucho | uszy | ear → ears |
| duch | dusza | spirit → soul |
| strach | straszny | fear → frightful |
| suchy | susza | dry → drought |
When you are unsure about a native word, try to build a diminutive or a related verb and listen for sz. If it appears, the original is spelled ch.
Mucha wpadła do kuchni przez okno.
A fly flew into the kitchen through the window.
Lubię słuchać radia przy śniadaniu.
I like listening to the radio at breakfast.
Rule 2 — ch at the end of a word or syllable. Final is written ch, never h. This matters enormously because of one extremely frequent grammatical ending: the locative plural of nouns and adjectives is always -ach, spelled with ch.
| Word | Form | Meaning |
|---|---|---|
| dach | dach | roof |
| gmach | gmach | large building, edifice |
| noga → nogi | na nogach | on (one's) feet/legs |
| książka → książki | w książkach | in books |
| dom → domy | w domach | in houses |
There is no Polish locative-plural ending -ah. If you ever feel tempted to write na nogah or w domah, stop — the ending is -ach, full stop.
W tych starych domach mieszka się przyjemnie.
Living in these old houses is pleasant.
Całe popołudnie spędziliśmy na nogach.
We spent the whole afternoon on our feet.
When to write h
Rule 1 — h alternates with g, z, or ż. This is the mirror image of the sz-test. If a related word has g, z, or ż where the sits, write h. Historically the [ɦ]/[h] developed from those voiced consonants.
| h-word | Related form | Meaning |
|---|---|---|
| wahać się | waga | to hesitate → weight/balance |
| druh | drużyna | companion/scout → team, troop |
| błahy | błazen | trivial → jester (same old root) |
These alternations are rarer than the ch↔sz one, so don't rely on them as your first instinct — but when you spot g/z/ż in a cousin word, h is confirmed.
Nie wahaj się zadzwonić, jeśli będziesz czegoś potrzebować.
Don't hesitate to call if you need anything.
Rule 2 — h in international borrowings. This is where most h words live. Greek, Latin, German, and other loanwords brought their h spelling with them. If a word looks international and has cognates you recognise from English, it almost certainly takes h.
| Polish | Meaning | English cognate |
|---|---|---|
| historia | history | history |
| humor | humour, mood | humour |
| hotel | hotel | hotel |
| bohater | hero | (Gk. cognate) |
| alkohol | alcohol | alcohol |
| harmonia | harmony | harmony |
Czytam teraz książkę o historii Polski.

Zarezerwowałem pokój w tym hotelu obok dworca.
I booked a room at that hotel next to the station.
The high-frequency h words to memorise
Because h is the minority spelling, the efficient strategy is to memorise the everyday native-feeling h words as a closed list, then treat everything else as ch by default. These are the ones that come up in daily life and that learners most often misspell:
- herbata — tea
- honor — honour
- handel — trade, commerce (→ handlować to trade)
- huragan — hurricane
- hałas — noise
- hak — hook
- hamować — to brake
- hojny — generous
- huśtawka — swing (playground)
- wahać się — to hesitate
Napijesz się herbaty czy wolisz kawę?
Will you have some tea, or do you prefer coffee?
Na drodze był taki hałas, że nie mogłam zasnąć.
There was such noise on the road that I couldn't fall asleep.
ch and h are not cz or sz — keep the categories separate
A separate confusion for beginners: ch/h is a throaty sound made at the back of the mouth, completely different from cz [t͡ʂ] ("ch" as in church) and sz [ʂ] ("sh" as in shoe), which are made at the front with the tongue. English "ch" and "sh" map onto cz and sz, never onto ch. So Polish chleb does not start like English cheese — it starts with the loch rasp. Don't let the Latin letters fool you.
Chętnie pomogę, ale nie mam dziś czasu.
I'll gladly help, but I don't have time today.
Common Mistakes
❌ Napiję się cherbaty.
Incorrect — 'tea' is a borrowing and takes h, not ch.
✅ Napiję się herbaty.
I'll have some tea.
English-speakers, primed by the rule that native words take ch, sometimes over-apply it to a loanword. Herbata feels native but isn't.
❌ Mieszkamy w dwóch starych domah.
Incorrect — the locative plural ending is -ach, never -ah.
✅ Mieszkamy w dwóch starych domach.
We live in two old houses.
The locative plural -ach is one of the most frequent endings in the language. Writing -ah is a pure spelling slip, since the is final and final is always ch.
❌ Interesuję się historią chemii.
Half-right: 'history' takes h, but here see the contrast — learners sometimes write *chistoria*.
✅ Interesuję się historią chemii.
I'm interested in the history of chemistry.
International words like historia and chemia take h/ch by etymology — historia with h (Greek/Latin), chemia with ch (Greek khēmeía). They cannot be guessed by feel; learn them as loanword spellings.
❌ Nie wachaj się, po prostu zadzwoń.
Incorrect — 'to hesitate' takes h because it alternates with waga.
✅ Nie wahaj się, po prostu zadzwoń.
Don't hesitate, just call.
The cousin word waga ("weight, balance") has a g, which is the tell-tale sign that wahać się takes h, not ch.
❌ Bałam się straha.
Incorrect — 'fear' is strach, with final ch (alternates with straszny).
✅ Bałam się strachu.
I was afraid (lit. I feared the fear).
The diminutive/adjective straszny shows sz, confirming ch in strach. Run the sz-test whenever a native word's spelling is in doubt.
Key Takeaways
- ch and h are pronounced identically in the standard; the choice is etymological.
- ch is the default: write it when the word alternates with sz (mucha → muszka) and at the end of any word or syllable — crucially in the locative plural -ach.
- h is the marked minority spelling: write it when the word alternates with g/z/ż (wahać → waga) and in most international borrowings (historia, hotel, alkohol).
- Memorise the everyday h list (herbata, honor, handel, huragan, hałas…) and default to ch for everything else.
- Don't confuse the throaty ch/h with the front sibilants cz [t͡ʂ] and sz [ʂ].
