h — two kinds, and neither is pronounced

but one of them blocks elision and liaisonA2

In one line

h is never pronounced in French — but an aspirated h behaves like a consonant and blocks elision and liaison.

Ignore the name. "Aspirated" suggests the breathy English h in hat. It is not pronounced at all. French has no /h/ sound anywhere — l'homme is /lɔm/, le héros is /lə e.ʁo/, and neither has a breath in it. The difference between the two kinds of h is entirely about what happens to the word before it.

Nothing in the spelling tells the two apart. It has to be memorised with the word — like gender.

In dictionaries an aspirated h is marked with an asterisk or an apostrophe: *héros or 'héros.

héroïne (heroine) has a silent h even though héros is aspirated. That is a genuine exception and must be learnt separately: l'héroïne but le héros.

A rough signal — where the word came from

OriginKind of hPronunciation
Latin and Greeksilent — homme
heure
histoire
/ɔm/ · /œʁ/ · /is.twaʁ/
Germanic, English, Arabicaspirated — haricot
hockey
hasard
/a.ʁi.ko/ · /ɔ.kɛ/ · /a.zaʁ/

The reason is that Latin had lost its /h/ centuries earlier, so Latin words entered French with a purely written h. Germanic and Arabic words brought a real /h/ with them, and although the sound later disappeared too, the consonant-like behaviour stayed.

This test is unusually reliable if you speak English, because you can run it from your own vocabulary. If the French word looks like a plain Germanic English word — hall, hockey, hobby, hamburger, handicap, harbour — the h is aspirated. If it looks like a Latinate English word — hotel, hour, history, honour, habit, hospital, humour — the h is silent. And those Latinate ones are precisely the English words where the h is silent or wobbly in English too: an hour, an honest man, an herb in American English.

The rule holds about 80 per cent of the time — not enough on its own, but useful.

What difference it actually makes

silent haspirated h
articlel'hôtel /o.tɛl/le haricot
pluralles hôtels /le.z‿o.tɛl/les haricots /le a.ʁi.ko/
possessivemon habitude /mɔ̃.n‿a.bi.tyd/ma haine
adjectiveun bel homme /œ̃ bɛl ɔm/un beau haricot
demonstrativecet hôtel /sɛ.t‿o.tɛl/ce haricot
negativeJe n'hésite pas. /ʒə ne.zit pa/Je ne hurle pas. /ʒə nə yʁl pa/

ma haine, not mon haine — because an aspirated h counts as a consonant, so the feminine possessive stays as it is.

In today's speech the line is blurring

Younger speakers often make the liaison with an aspirated h anyway:

les haricots /le.z‿a.ʁi.ko/ — common in speech, wrong in an exam

The Académie does not accept it, and it must be observed in writing and in formal speech.

Why a letter with no sound matters so much

a dead sound whose behaviour survived it

In Classical Latin h had a sound — a light breath, like the English h.

But it had dropped out of speech by the first century AD. Romans could not hear the difference between honor and onor, and their poets made jokes about it.

So Latin words entering French had a silent h — a purely orthographic letter.

Then a second wave arrived: Germanic words from the Franks and Arabic words through Spain and trade — and these brought a real /h/ sound with them.

WordFrom
haricot /a.ʁi.ko/probably Germanic, via the Old French verb harigoter ("to cut into pieces")
hasard /a.zaʁ/Arabic az-zahr
haine /ɛn/Frankish
hache /aʃ/Frankish — happja

That sound was gone by the sixteenth century too — but by then the language had learnt that these words behave "like consonants", and the behaviour outlived the sound.

So the aspirated h is a dead sound with only its shadow left: it blocks elision and liaison without ever being heard.

English preserves one small piece of the same history. You say "an hour" but "a house" — English also treats one set of h words as vowel-initial and another as consonant-initial, for the same reason: Latin words arrived with a silent h, Germanic words with a real one. French l'heure versus le haricot is English "an hour" versus "a house", one layer deeper.

The practical point: the list is short — about a hundred words, of which perhaps twenty are genuinely frequent. Memorise those with their article: le haricot, le héros, la honte, le hasard. Learn the rest as you meet them.
