The letter "h" is a constant source of confusion for English learners — and with good reason: depending on the word, it is either pronounced clearly or not at all, it disappears in fast speech, and it hides inside other spellings where it changes the sound around it. Here is everything you need to stop second-guessing yourself.
What the English H Actually Is
The English /h/ is a real consonant: a puff of breath from the throat, made with the mouth already in the position of the following vowel, as if fogging a mirror. It is not a "silent letter that blocks liaison" as in French, nor a throat-scraping sound as in Spanish or Arabic. Hold your hand in front of your mouth and say "house": you should feel warm air on your palm before the vowel. That puff is the whole sound.
The Aspirated H: When You Can Hear It
In the vast majority of English words, the "h" is aspirated. Because the word then begins with a consonant sound, it takes the article "a". Common examples: a house /haʊs/, a hotel /həʊˈtel/, a heart /hɑːt/, a hero /ˈhɪərəʊ/, a habit /ˈhæbɪt/, a hospital, a history, a horse, a hundred, a happy child. In all these cases the "h" is fully audible — there is no swallowing it, and dropping it ("I 'ave a 'ouse") is one of the most noticeable errors a learner can make, because in Britain it is strongly associated with particular regional accents and the listener will hear it as such.
The Silent H: The Quiet Exceptions
A small group of words, almost all of French or Latin origin, have an "h" that is not pronounced at all. The vowel that follows becomes the first sound of the word, so the article is "an". The core list is short enough to learn by heart:
- hour /ˈaʊə/ — and hourly, hourglass
- heir /eə/ — and heiress, heirloom
- honour /ˈɒnə/ — and honourable, honorary
- honest /ˈɒnɪst/ — and honesty, honestly
- herb /ɜːb/ — in American English only; British English says /hɜːb/, "a herb"
A simple test: say the word aloud with a hand in front of your mouth. If you feel a puff of air, the H is aspirated; if not, it is silent. And notice that the silent-H words all carry the stress on the first syllable and come from French, where the H was already silent — English simply never added it back.
The Special Cases of "hotel" and "historic"
These two words have fuelled a debate for centuries. Historically, when the "h" was aspirated but the stress fell on the second syllable (ho-TEL, his-TOR-ic), the "h" was weak enough that some speakers chose "an" — and in the eighteenth century "hotel" was still pronounced the French way, with no H at all. You will still find "an hotel" or "an historic moment" in older texts and in very formal writing. Today these forms are widely regarded as old-fashioned. Modern usage favours "a hotel" and "a historic event", and this is what you should say. Only some traditional British writers still cling to "an historic", and it now sounds affected to most ears.
The Vanishing H of Connected Speech
Here is the part most textbooks leave out. The pronouns and auxiliaries he, him, his, her, have, has, had all begin with an aspirated H when said alone — but in the middle of a sentence, when unstressed, native speakers drop the H entirely and link the word to the one before:
- "Tell him" → /TEL-ɪm/ ("tell 'im")
- "I saw her" → /aɪ-SAW-ə/ ("I saw 'er")
- "What has he done?" → /WOT-əz-i-DUN/
- "They should have gone" → /ðeɪ-ʃʊd-əv-GON/ ("should've")
- "Is he here?" → /IZ-i-HIə/ — the H of "here" stays because the word is stressed
This is standard, not sloppy: even the most careful RP speaker says "tell 'im". The H returns whenever the word is stressed or at the start of a sentence: "HE did it", "HER, not him". For listening comprehension this matters enormously — a learner waiting to hear "him" may never catch the /ɪm/ that actually arrives.
The Golden Rule
The choice between "a" and "an" depends on sound, not spelling. Seeing an "h" does not tell you which article to use — what matters is the first sound you actually pronounce. A vowel sound calls for "an"; a consonant sound, including an aspirated H, calls for "a". The same logic applies to every letter:
- "an MBA", "an FBI agent", "an X-ray" — the letter names begin with vowel sounds (em, ef, eks)
- "a university", "a European", "a used car", "a unicorn" — the words begin with the consonant sound /j/
- "a one-off", "a one-way street" — "one" begins with /w/
- "an honest man" but "a horse"; "an hour" but "a house"
The H is not an exception at all — it follows a rule that is perfectly consistent once you hear it rather than read it.
H Hiding in Other Spellings
The letter also appears in combinations where it is not a separate sound at all, and a few where it is silent for no good reason:
- ch, sh, th, ph — the H changes the preceding letter into a new sound: /tʃ/, /ʃ/, /θ ð/, /f/. It is never pronounced on its own.
- wh — in most accents simply /w/: what, when, where, which, while. But in who, whom, whose, whole the W is silent and the H is pronounced: /huː/, /həʊl/.
- gh — silent or /f/: night, though, daughter; laugh, enough, cough. Never /g/ except at the start: ghost, ghetto.
- rh — silent: rhythm, rhyme, rhino, rhubarb.
- Silent H in the middle: vehicle /ˈviː-ɪ-kəl/, exhaust /ɪg-ˈzɔːst/, exhibition /ek-sɪ-ˈbɪ-ʃən/, shepherd /ˈʃe-pəd/, ghost — and in names: Thames /temz/, Thomas /ˈtɒ-məs/, Anthony (British /ˈæn-tə-ni/).
A Surprising Advantage for French Speakers
The English words with a silent H almost all come from French: hour (heure), heir (héritier), honour (honneur), honest (honnête). For French speakers, recognising them tends to come naturally. It is one of the rare cases where your mother tongue gives you a head start — so make the most of it. Just remember that the reverse is not true: most other English "h" words (house, hospital, history, hotel, humour) are fully aspirated, unlike their French cousins, and the French habit of leaving every H silent is the error to fight hardest.
