Does "I have a daughter" mean "I have one daughter"?



Let's say I have two daughters and someone asks me:

Do you have a daughter?

Should I respond "yes" or "no"? In other words, does "I have a daughter" mean "I have one daughter"?

You would say: Yes, and actually/in fact I have two. Unless you did not want to reveal you have more than one daughter, in which case a simple Yes is fine. You could also say no if you felt the asker has no business knowing how many daughters (if any) you have. – Alan Carmack – 2016-05-20T19:05:04.377

@AlanCarmack Depends on the context. If, say, someone said, "We're having a seminar for fathers of girls. Do you have a daughter?", the number probably doesn't matter, they're just asking if I have any, so I might well just say "yes". On the other hand, if someone said, "We're giving out free samples of this product for girls, one to each girl. You sir, do you have a daughter?" Assuming I thought my daughters would want the free sample, I'd presumably say that I have two so I'd get two samples. Etc. – Jay – 2016-08-26T01:34:23.527

27As a native English speaker, but also a computer programmer by trade, I would say that responding "Yes" to "Do you have a daughter" means you do have one daughter, but doesn't imply that it's your only daughter. If I asked you "Do you own a book" you wouldn't say "No" if you owned multiple books. – FreeAsInBeer – 2015-01-28T13:40:22.200

2How about something like 'Actually, I have two'? Of course, provided that you do want to give this private information away of yourself. – András Hummer – 2015-01-28T14:48:21.677

1The same always occurs to me when asked (also in my native language) "Do you have children?". Fortunately for me, this ambiguty has been resolved by nature ... – PlasmaHH – 2015-01-28T16:35:10.207

Perhaps the end of the question should be edited to say "I have exactly one daughter" – Aaron McDaid – 2015-01-28T18:11:20.040

2It depends who is asking and why they want to know. – None – 2015-01-28T18:18:12.797

3@δοῦλος Sure. Depending on who's asking, the correct answer might be, "Yes. And she has 3 brothers who are all over 6 feet tall and play football. And we're all going home right now because we have to clean our guns. Why do you want to know?" – Jay – 2015-01-28T18:44:56.293

2@Jay I simply point out that language is for communication. Trying to dissect one isolated sentence as if it were a laboratory specimen or a logic puzzle is misguided. – None – 2015-01-28T21:48:40.283

Since this site is about actually learning the language, shall we assume you're not asking someone fond of Dad Jokes? – corsiKa – 2015-01-28T22:26:22.460

1I think the clearest response in the situation would be something like "Yes, in fact, I have two." – Kevin – 2015-01-29T14:11:32.577

2I've no idea why the comment made by computer programmer @FreeAsInBeer has met with such approval. Human language is not a computer language and allows for much more ambiguity and freedom; it is also not tied down to logic problems. I quite like the sentence of new user jfren484 that A native English speaker will never, in seriousness, ask that question on its own with the intention of asking if you have exactly one daughter, although never is perhaps too strong. – None – 2015-01-29T19:11:31.820

1@δοῦλος That's probably actually because unless you're an insurance agent or a healthcare clerk, you would almost never ask anyone if they have exactly one daughter, no matter the sentence. That's just a strange thing to ask. But FreeAsInBeer's comment about books in a library is spot on: I have a few shelves full of books. If someone asks if I have a book, I'd say "Yes, I do." Of course, if someone asks if I have a daughter, I'd say "Yes, I have two." And then I wouldn't shut up about them for 20 minutes, but that's another story. – corsiKa – 2015-01-29T19:27:39.057

@corsiKa One could ask who in the h3ll is going to ask anyone Do you own a book? :) – None – 2015-01-29T20:25:34.840

@δοῦλος: FreeAsInBeer's comment is upvoted because it is correct: if someone asks "Do you have a daughter?" and you say "Yes," that means you have a daughter, but not necessarily only one. Your comment reads more like a response to what you imagine a programmer would say, rather than what was actually said. – Nick Matteo – 2015-01-30T16:07:11.427



"I have a/an X" does not necessarily mean that I have exactly one X, it just means that I have one or more.

Suppose someone was looking for a ride home, and he asked, "Do you have a car?" If you own two cars, you wouldn't say, "No". You probably wouldn't even find it necessary to say, "I have two cars". You'd just say "Yes". (Well, unless you're looking for an excuse to not give him a ride.)

Suppose your local school announced they were having a "father/daughter dance", and said, "This is open to any man who has a daughter in this school." If you have two daughters, would you conclude that you were not welcome? Almost certainly not.

Or to take it a step further, if someone asked, "Do you have a daughter?", and in fact you have one daughter and one son, would you say, "No, I don't?" Probably not. Or if someone asked, "Do you own a cell phone?", would you say "no" because you own a cell phone and you own a laptop computer and you own a car and you own six pairs of underwear, etc? Normally, asking if you "have X" doesn't imply "and nothing else". If you want to specify "and nothing else", you normally need to add some words, like "only" or "just one". Like if someone asked me, "Do you have only one daughter?", I would answer, "No, I have two." I might also say that I have two sons as well, if the context of the question implied that the person was asking if I had only daughters.

All that said, there may be contexts where it would be understood to mean exactly one. I can't think of one, but I can think of a somewhat similar example. Suppose someone said, "In this country it is illegal for anyone under 18 to buy alcohol." If in fact the law said it is illegal for anyone under 21 to buy alcohol, there's a sense in which the statement is technically accurate: Yes, it is illegal for anyone under 18 to buy alcohol. But it is also illegal for anyone between 18 and 21 to buy alcohol. But as worded the sentence is very misleading. It implies that anyone over 18 can buy alcohol, without actually saying that.

I suppose if someone said, "We are holding a conference for parents of girls being raised without any brother or sisters, only children who are girls. You sir, do you have a daughter?" Clearly then he means exactly one, but this example is highly contrived.

"there may be contacts where it would be understood to mean exactly one. I can't think of one". For example: "How many daughters do you have?", "I have a daughter" means just one. Or you can (and normally would) emphasise: "Do you have two daughters?", "I have a daughter". I suppose that on the witness stand you could still claim that "technically" this didn't mean exactly one. But it is at least intentionally misleading to say it if you have two, even if "technically" not lying. – Steve Jessop – 2015-01-28T16:48:05.707

6In your final example, I would still interpret the question as "do you have at least one daughter" - and anticipate his next question to be "is she an only child?" or "do you have any other children?". – Brilliand – 2015-01-28T17:16:17.487

2@SteveJessop I think if someone asked "How many daughters do you have?", you might answer, "One", or "I have one daughter". Few would reply, "I have a daughter." That said, if someone asked, "How many children do you have?", you might reply, "I have a daughter", meaning just one, and no sons. – Jay – 2015-01-28T18:09:23.403

1@adam Oops, typo. Fixed. – Jay – 2015-01-28T18:09:40.427

1@brilliand That's probably more likely, I'll give you that. It COULD be interpreted to mean just one, but as you say, still more likely to mean at least one. – Jay – 2015-01-28T18:10:40.773

In your last example, the speaker says, "We are holding a conference." In that context, he's only holding one particular conference, not one or more. – Kevin – 2015-01-28T22:51:11.480

1@kevin Umm, no. If someone said, "We are holding a conference on such-and-such subject", would you take that to mean that this is the first and only conference they have ever held? I wouldn't conclude that at all. If someone said, "We are holding a conference on the history of language. This will be our tenth annual conference", I can't imagine anyone saying that this was a contradiction, that the "a" in the first sentence means that they have only ever held one conference while the second sentence says that they have held ten. He's only talking about one particular conference at the moment... – Jay – 2015-01-29T02:26:11.870

... but that doesn't mean he hasn't held others. In exactly the same way, if someone said, "I have a daughter, and yesterday she said the funniest thing ..." I wouldn't understand that to mean that he only has one daughter, but that he is only talking about one right now. – Jay – 2015-01-29T02:26:43.113

@Jay so, "a/an X" is just "at least one X", after all? – user132181 – 2015-01-29T06:43:35.563

1@Jay If someone said "Do you have any children?" then it makes sense to reply "I have a daughter" specifically meaning one. – JamesRyan – 2015-01-29T16:10:43.533

Try "How many children do you have?" – Colin McLarty – 2015-01-29T18:22:23.713

@JamesRyan Probably true, though I'd consider that a slightly odd answer. If a politician gave an answer like that I'd immediately suspect he was hiding something. Like, "How many campaign contributions have you received from oil companies?" "I did receive a contribution of $100 from an oil company last month." I'd suspect he's trying to make it sound like that was the only one while giving himself room to weasel out if he gets caught. Of course I wouldn't normally expect someone to have a reason to lie about how many children he has, so in that context I'd probably just think it odd wording. – Jay – 2015-02-02T07:01:27.907


You asked about answering "yes" or "no". If the question is "do you have a daughter" and you have one, two or more daughters, then the correct answer is "yes".

However, if I ask the question, I might get the answer "yes, I have a daughter" and the problem is: Does the person have exactly one daughter or possibly more than one?

It depends on the context. Let's say I have trouble with my daughter and some know-it-all is trying to give me advice, which really gets on my nerves. So I ask "do you have a daughter?" because that kind of unwanted advice often comes from people who know nothing. In that case an answer "yes, I have a daughter" means one or more daughters. My question really meant "do you know what you are talking about" and the answer meant "yes, I know what I'm talking about".

In other situations, you would expect "I have a daughter" to mean "I have one daughter", and you would expect a different answer like "I have two daughters" from someone with more than one daughter. Then of course it depends on how much of a pedant the person is, so your expectation might be wrong.

The long standing play on words relating to this subject is this joke:

"Hey, you got a haircut!" "Actually, I got all of them cut!"

This is funny (or supposed to be funny) exactly because "a haircut" (the act of getting your hair cut) sounds exactly like "a hair cut" (you got exactly one of your hairs cut), and the deliberate misinterpretation is unexpected.

The fact that this answer is unexpected highlights how strange it would be to me to answer anything other than "Yes" to the original questioner.

How is No, I have two daughters an "incorrect response"? It's a correct response out of several that could be given. – Alan Carmack – 2016-05-20T19:02:04.423

1This is not an answer. – None – 2015-01-28T21:54:42.663

I think it is an answer, but it could use more explanation to make it clearer for a non-native speaker. Maybe elaborate on how "Do you have a daughter?" could be answered with "Yes, I have three daughters." – ColleenV – 2015-01-28T22:09:10.247

1It's proof by counter-example, and the point I'm trying to illustrate is that replying "No, I have two daughters" is an incorrect response. Plus, these are the sorts of plays on words that ESL students that I taught always seemed to appreciate, so I figured this would be an example that could add to the discussion. – Kyle – 2015-01-28T23:01:49.650

2It does add to the discussion, and I think it would be a stronger answer if you circled it back to the original question a little more explicitly. – ColleenV – 2015-01-29T00:22:43.017


"I have a daughter" does mean you have only one, though it's correct to ask "do you have a daughter" if you're not sure if the person has one, none, or multiple daughters. The correct answer is "yes, I have two daughters."

4You might also ask, "Do you have any daughters?" which would make a simple "Yes" answer's ambiguity clear. "Do you have any daughters?" "Yes." "How many?" "Three." "Why do you only respond in monosyllables?" "'Cause." – Jason Patterson – 2015-01-28T12:33:30.763

4I disagree. You say that: The correct answer is "yes, I have two daughters." It's certainly also correct to answer "Yes, I have a daughter," even though I have three. If someone I don't know asks me, "We have a daddy/daughter dance. Do you have a daughter?" I might easily say, "Yes, I have a daughter." It's simply unnecessary to provide more information. – Paul Senzee – 2015-01-29T02:01:32.423

Of course, as Julio mentions, additional context could change the fact that "I have a daughter" generally means you have only one. Someone could ask me, "Do you have a daughter?" and I could answer with something like, "Yes, I have a daughter living at home, and two more who live in California." In that context, a daughter still refers to one daughter, but it doesn't mean I have only one. – J.R. – 2015-01-31T11:34:29.377

Someone could say 'I have a daughter who does ballet', but they could have other daughters who don't. – None – 2015-01-29T11:35:18.500


In common usage, the question "do you have a daughter" usually carries with it an implied elaboration in the response, since "a" does NOT literally mean "one" in this context.

If you had one daughter, a typical response might be "yeah, a 9 year old girl" or "I do, she's in college", or simply "yes, I do".

If you had two or more, you might say "I have two of them, a 9 year old girl and another in college" or just "two of them".

If I had to put a rule to how it's commonly used (in my experience), I'd say:

  • for 0 daughters, say that you do not

  • for 1 daughter, say that you do, and a small piece of information as well, such as her age or any basic descriptor

  • for 2 or more daughters, it's acceptable to just say how many you have, with any extra information being completely optional to include

On its own, "I have a daughter" does mean "I have one daughter". (An exception might be if you've just now got/learned of the newest daughter, by birth or prenatal testing results or adoption or a transgender announcement.) In response to the question "Do you have a daughter?", "no" alone means "I have zero daughters."

Other than that, the answer will depend on the reason for the question. As it happens I do have two daughters, but won't always say that if the person is clearly only asking about one of them, or if one is enough.

"I saw a teenager who looks just like you. Do you have a daughter?" "yes" "I'm seeking the opinions of mothers of girls for a study. Do you have a daughter?" "yes"

If the person is asking in a conversational way, an answer of just "yes" would be almost as weird as an answer of "no". It would be appropriate to say something about my daughters and ask about theirs.

"Do you have a daughter?" "Yes, two in fact, they're 16 and 19."

I skimmed other answers and didn't find any mention of articles, so I'll just add some information about grammar:

The word a in English is an indefinite article. It is used in the following situations:

  1. before phrases of time and measurements (per week/weekly)

    I go to English class 4 times a week

    • you can also use per week here
  2. before phrases of jobs

    I am a doctor

  3. with a noun complement

    Do you have a daughter? Yes, I have a daughter

    • This is your case
    • Note that if you have more than one daughter, you would start numbering how many: I actually have three daughters!
  4. before phrases of nationality (very rarely)

    He is an American

    • This is not used often, only when the nationality is being used as a noun phrase (as used above). Some more examples/exceptions:
      1. She is a native French speaker (the noun phrase is in bold).
      2. She is a French
        • This is incorrect because French is being used as an adjective to describe the woman; it is not a noun phrase
  5. half/quite with a noun phrase

    He is quite a handsome man

    The recipe requires half a cup of sugar

To expand on the answer mentioning indefinite articles...

The words "a" and "an" are indefinite articles. By definition, this means that they do not refer to a specific quantity - "a" and "an" mean "at least one". The word "the" is called a definite article, and refers to a single entity.

A native English speaker will never, in seriousness, ask that question on its own with the intention of asking if you have exactly one daughter.

1+1 especially for your closing sentence. Although perhaps never is too strong. I referenced your sentence in a comment to the OP. Welcome to SE/ELL. – None – 2015-01-29T19:12:34.367


Yes this does mean you have ONE daughter. If you were asking how many children someone had you would say "how many children do you have". This could mean single or multiple children!
