BOH, MAH, BEH in Italian: What They Really Mean (And How to Use Them)
Indice
BOH, MAH and BEH are some of the most common words in spoken Italian — and you’ll almost never find them in a grammar book. They look interchangeable, but they’re not: each one carries a different shade of meaning. Here’s what each one actually means and when to use which.
BOH: what it means and when to use it
BOH means “I don’t know” or “no idea” — but not in a serious way. It’s spontaneous, almost physical: when an Italian says “boh,” they usually shrug at the same time.
When to use it:
- When you don’t know something Che ore sono? — Boh, non ho l’orologio. — “What time is it? — No idea, I don’t have a watch.”
- When you have no opinion Che film guardiamo stasera? — Boh, per me è uguale. — “What movie should we watch tonight? — I don’t know, I don’t mind either way.”
- When something doesn’t make sense to you Perché Marco non risponde al telefono? — Boh! — “Why isn’t Marco answering the phone? — No idea!”
Mini-dialogue:
Luca: Sai se domani piove? — “Do you know if it’s raining tomorrow?” Marco: Boh. Guarda il meteo. — “No idea. Check the weather.” Luca: E dove andiamo a cena? — “And where are we going for dinner?” Marco: Boh, decidi tu. A me va bene tutto. — “No idea, you decide. I’m fine with anything.”
MAH: what it means and when to use it
MAH expresses doubt: “I’m not convinced,” “I have my doubts about this.” When an Italian says “mah,” they’re weighing something up — they’re not sure.
BOH = I don’t know (neutral) · MAH = I have my doubts (skeptical)
When to use it:
- When you’re not convinced by something Ti piace questo ristorante? — Mah, non tanto. — “Do you like this restaurant? — Hmm, not really.”
- When something doesn’t add up Dice che arriva tra cinque minuti. — Mah, io non ci credo. — “He says he’ll be here in five minutes. — Hmm, I don’t believe it.”
- When you’re undecided Andiamo al mare o in montagna? — Mah… forse al mare. — “Beach or mountains? — Hmm… maybe the beach.”
- When something sounds odd to you Luca dice che ha smesso di mangiare la pasta. — Mah! — “Luca says he’s stopped eating pasta. — Really?! I doubt it!”
Mini-dialogue:
Sara: Com’è andato l’appuntamento con Giacomo? — “How did the date with Giacomo go?” Giulia: Mah… così così. — “Hmm… so-so.” Sara: Ma ti piace o no? — “But do you like him or not?” Giulia: Mah, è simpatico, però… non lo so. Non sono convinta. — “Hmm, he’s nice, but… I don’t know. I’m not convinced.” Sara: Cioè, lo rivedi? — “So, are you seeing him again?” Giulia: Mah… vediamo. — “Hmm… we’ll see.”
Giulia says “mah” three times — not because she doesn’t know, but because she has doubts. She’s skeptical, which is a different feeling from “boh.”

BEH is completely different from the other two. It’s used to start a sentence — it’s the Italian equivalent of “well” in English. We use it to introduce an opinion, an answer, or a conclusion.
BOH = I don’t know · MAH = I have my doubts · BEH = well… (introducing something)
When to use it:
- To start an answer Come stai? — Beh, non malissimo. — “How are you? — Well, not too bad.”
- To say “obviously” Sono stanco dopo 12 ore di lavoro. — Beh, certo! — “I’m tired after 12 hours of work. — Well, obviously!”
- To change topic or wrap up Beh, comunque, parliamo d’altro. — “Well, anyway, let’s talk about something else.”
- To express impatience Allora, vieni o no? — Beh, aspetta un attimo! — “So, are you coming or not? — Well, wait a minute!”
Mini-dialogue:
Mamma: Come è andato l’esame? — “How did the exam go?” Figlio: Beh… non benissimo. — “Well… not great.” Mamma: Cioè? Che voto hai preso? — “Meaning? What grade did you get?” Figlio: Beh… diciamo che devo rifare l’esame. — “Well… let’s just say I have to retake it.” Mamma: Beh, te l’avevo detto di studiare di più! — “Well, I told you to study more!”
“Beh” doesn’t express doubt and doesn’t mean “I don’t know” — it introduces the sentence, buying a little time before saying what comes next.
Quick reference: BOH vs MAH vs BEH
| Word | Meaning | English equivalent | Example |
|---|---|---|---|
| BOH | I don’t know, no idea | I don’t know / No idea | Dove sono le chiavi? — Boh! — “Where are the keys? — No idea!” |
| MAH | I have my doubts, not convinced | Hmm / I’m not sure / I doubt it | Ti piace? — Mah, non tanto. — “Do you like it? — Hmm, not really.” |
| BEH | Introduces a sentence, buys time | Well… / So… | Com’è andata? — Beh, così così. — “How did it go? — Well, so-so.” |
Common mistakes with BOH, MAH, BEH
- Using BOH when you mean MAH: BOH is neutral ignorance (“I have no clue”); MAH carries skepticism or doubt (“I’m not sure I believe that”). Mixing them up makes you sound less certain — or less doubtful — than you actually are.
- Treating BEH as a synonym of “I don’t know”: BEH never means uncertainty. It’s a sentence-starter, closer to “well” than to “boh” or “mah.”
- Overusing all three in formal writing: these are spoken, colloquial words. Natural in conversation with friends, out of place in formal or written Italian.
