מי, מה, איזה as Pronouns

Learn the three words — מִי, מָה, אֵיזֶה — and you have the vocabulary of this page in a minute. The part worth ten minutes is what happens to the rest of the sentence when you use them, which in Hebrew is: nothing at all.

Fronting is the whole operation

English builds a question by taking a statement apart. He is coming tomorrow becomes when is he coming? — the auxiliary jumps in front of the subject. He wants this becomes what does he want? — an auxiliary that was not in the statement has to be invented and inserted. Hebrew does neither. The question word normally goes in the first slot, while the clause keeps ordinary statement order. The questioned noun is replaced, of course, and replacing a subject can reset the verb's agreement.

Look at the verb in the last row. The statement had הביאה, feminine, because Dana brought it; the open question has הביא, masculine singular, because מי has no gender of its own and masculine singular is the default when the answer is not yet narrowed down. Agreement can nevertheless follow a known set of candidates: in a room where everyone is female, מי הביאה? is natural. מי itself never changes; the verb reflects what the speaker already knows about the possible answer.

One thing does move, and it is the exception that proves the point. A preposition cannot be left behind at the end: who are you talking to is עם מי אתה מדבר, with the עם travelling to the front alongside מי. That is not inversion — it is the question word taking its preposition with it — and it has its own page, prepositions in front of a question word.

מי — people

מי asks about a person and about nothing else. It has one form: no gender, no plural, and no case.

Notice מי זאת. When you ask who is that? about someone you can see, Hebrew pairs מי with a demonstrative, and the demonstrative agrees with the person: מי זה about a man, מי זאת about a woman, מי אלה about a group. מי itself never changes. The answer frame mirrors the question — זה or זאת plus the identification, not a personal pronoun:

מה — things

מה asks about a thing, an event or an idea. It too has one form.

Why מה keeps changing its vowel in pointed texts

Unpointed, מה is one spelling. Pointed, it has three shapes, and the conditioning is classical. Gesenius §37 sets it out:

The logic is the definite article's, exactly. הַ־ doubles the consonant after it; when that consonant is a guttural and refuses to double, the vowel lengthens instead to compensate. מַה־ behaves the same way — and not by coincidence, since its dagesh comes from a consonant that was once part of the word itself.

None of this reaches your mouth: all three read ma in Israeli Hebrew, and unpointed writing spells them all מה. It matters only when you are reading a pointed text and the word appears to keep shifting shape. You will also see it claimed online that the Academy of the Hebrew Language recommends מָה across the board; that claim could not be corroborated for this guide, so it is not repeated here as an Academy position.

מהו, מהי, מיהו — the fused forms

מה and מי can fuse with a following third-person pronoun: מהו (máhu, from מה הוא), מהי (máhi, from מה היא), מיהו (míhu) and מיהי (míhi). They are formal and written — a report, a headline, an exam question, a definition. Everyday speech uses מה זה and מי זה instead, or simply מה and מי.

איזה, איזו, אילו — picking one out of a set

Unlike מי and מה, this one agrees, because it modifies a noun.

Check the noun's gender before you choose, and check it in a dictionary rather than by the ending — this is precisely the position where a guess goes wrong, because there is no second agreeing word to catch it.

That table describes careful agreement. In relaxed conversation Israelis commonly level the feminine and plural forms to איזה, so איזה can appear in front of a plural noun without a second thought:

The same forms can also stand without an overt noun when the alternatives are already clear:

Answering

A question word is only half a pattern. These are the frames that answer them:

Common Mistakes

1. Using מי for whose. English who covers both, Hebrew's does not: possession is של, and the question word attaches behind it.

2. Putting מה in front of a noun. English what book, what time, what colour all use what as a determiner. מה cannot do that job at all.

3. Translating English do-support as עושה. In what does he want?, English does is only a grammatical support word; it is not the verb do and has no Hebrew translation.

4. Matching איזו to a masculine noun. The ending is not decoration: careful איזה / איזו / אילו agreement follows the noun's actual gender and number.

Key Takeaways

• A Hebrew content question normally fronts the question word but keeps ordinary clause order. There is no English-style inversion or do-support: מתי הוא בא is word for word when he comes.
• מי asks about people and מה about things. Neither inflects for gender, number or anything else.
• מי זה / מי זאת / מי אלה — the demonstrative beside מי agrees with the person, and the answer uses the same demonstrative: זאת השכנה.
• איזה / איזו / אילו does agree, because it modifies a noun. Check the noun's real gender, not its ending.
• איזה / איזו / אילו are the careful forms; relaxed speech often levels feminine and plural alike to איזה.
• מהו, מהי, מיהו are fused and formal. Conversation says מה זה and מי זה.
• מה's three pointings — מַה־, מָה, מֶה — are a classical rule about gutturals and the dagesh. All three read ma, and unpointed Hebrew writes one spelling.
• When מי replaces an unknown subject, masculine singular is the default (מי הביא?), but a known all-female candidate set naturally permits מי הביאה?.
