How to use the word ma'am. When and in which situations can I use this word? Which women can I greet with this word?

I have seen this word being employed in the Harry Potter and the Philosopher's Stone movie when Ron Weasley (Rupert Grint) spoke to professor Minerva McGonagall (Maggie Smith). But this is a fairy tale!

    What country are you in? (or whom do you plan on speaking English with?) As the answers mention below, English speaking countries seem to vary in the usage. Also, within the US itself, usage of ma'am" (and "sir") can break down (and even carry slightly different meaning/understanding) whether you're in the North or South.

It depends on what country you're in. In Ireland (where I'm from) and the UK (where I live right now) 'ma'am' is pretty much never used. However, sometimes people working in shops/restaurants etc might use 'madam' – but it would be very strange to hear it outside that context. It's used for customers, not friends or acquaintances.

I think that in this part of the world, 'ma'am' sounds too old-fashioned.

If you are visiting the UK or Ireland and you are not an employee in a shop, you don't have to call anyone anything! If you need to ask someone for directions on the street, for example, just say 'excuse me' instead of 'excuse me ma'am/madam' etc. It's not necessary for politeness. In fact, using 'madam' (or 'sir') would most likely sound too formal for this context.

  • I was in shock when I moved from Canada to Texas. Ma'am is used here all the time and I think of it as old fashioned, too.

    It does fit with that idea of 'southern hospitality' in the US, though. I know very little about the US apart from what I come across in the media and films, but I get the impression that the southern states have their own, distinct hospitality culture, and I suppose that's why they have kept 'ma'am'.

In the East Alabama speech community I grew up in, ma'am was the feminine equivalent of sir addressed to men. It was conventional to use it to all women older than the speaker, and to younger women with whom the speaker was not on familiar terms.

I myself use both ma'am and sir to everybody, including the people I work with and very young children, who seem to take special pleasure in being treated as if they were grown-ups. (The children, that is—my colleagues are happiest when they're left alone to do their work.)

The consensus appears to be: if you're in the American South, use ma'am generously to any woman, pronouncing it /mæm/. Elsewhere, save it for a) your female superiors in the military and b) the Queen on your second and subsequent remarks to her.

    @ĽubomírMasarovič I've never heard /mɑ:m/ in the US; it's /mæm/ (more or less diphthongalized according to your idiolect), or contracted to /m/ following Yes. Commented Jan 22, 2017 at 18:39

    @ĽubomírMasarovič As a Briton myself, I can say that 'ma'am' is very rarely heard here in day-to-day conversation. Female teachers are called 'Miss', a female customer in a shop would most likely be called 'madam' (without contraction), and a stranger in the street would be unlikely to get a form of address beyond 'excuse me'. Police and army officers, as well as lower-ranking judges may well be an exception, just not one that I know of well. Commented Jan 22, 2017 at 21:56

    @ĽubomírMasarovič As a Brit, I'd just like to add a general point that we use "sir" with much less frequency than Americans do. I wouldn't usually expect to be called "sir" by a shopkeeper, for example. I think this applies even more to "ma'am"; we'd definitely rarely use it.

    If you meet the Queen, you should call her Your Majesty the first time you address her, then Ma'am from then onwards.

For me, this can be a loaded question.

Ma'am is often used in the military instead of "Sir", to a female of higher rank.

Ma'am is used to note respect to a woman with a noble title. You would not always say "Lady Susan", the maid could answer, "Yes, Ma'am." (In England, it often sounds like "Mum".)

Teachers in some institutions are called ma'am at the same times a man would be addressed as "sir". (We used "Miss" in my school.)

In the Southern US, a woman is called ma'am as a sign of respect. So a store clerk might say, "Here is your package, ma'am." In other places in North America, ma'am is a sign of respect.

This is why it can be loaded. I am Canadian and in the part of Canada I am from, a woman might easily feel like you are saying she is old. So a store clerk would call most women "Miss" instead. This doesn't mean they are unmarried, just that the woman is not old.

    @ĽubomírMasarovič Ms is absolutely fine. It can be used when you are addressing an envelope or using a woman's name in a letter. However, if you are talking to a woman of higher rank, then Ma'am is still the way to go. Ms is more casual still. Lady Susan would never be Ms., and nor would any higher rank in the military*. Each school would have their own set of practises, so you'd have to ask. *interestingly, there is a push to address higher ranking military women as "Sir".

    In the UK, senior female police officers are "ma'am", although they do tend to pronounce it "mum". Junior female judges are "ma'am", but the senior ones are "My Lady", or "Your Honour" (depending on rank).

    @WillowRex "Is a police officer not (at least) a pseudo-military officer?" Not in any organizational or legal sense, in the UK. In fact the UK's Royal Military Police are a separate organization, which is effectively the police force for the armed services only.

    @alephzero You don't say Ms as miz? That's pretty standard everywhere I've lived (all in the US). It's not so common to call out in the street to someone who dropped something as miss or ma'am or excuse me, but completely ordinary in front of a teacher's last name or with a hanging question mark when fishing for a stranger's name.

    @1006a in British English, you might refer to "Ms X" (pronounced "Mizz") but you'd never call someone plain "Ms". Calling people "Miss" sounds old fashioned or quaint enough. "Ma'am" would be very formal (I don't think I've ever used it) - the most likely use would be a courtroom. And as for "Lady Susan" apart from some very formal event when addressed by a stranger to whom the title had been made very obvious, I'd expect her to be addressed the same as anyone else called Susan (of the same age / familiarity).

In the context of English schools:

Prior to the second half of the 20th century, male schoolteachers would be referred to as "Sir" and female schoolteachers as "Miss". At that time, a married woman would not normally be permitted to remain as a teacher, so teaching was a career for unmarried women. With changing social attitudes women were not compelled to resign after marriage. This caused the conventions on what to call teachers to change.

Some schools continue to use "Miss", seeing this a word of respect, not an indication of marriage. Some use "Mrs Smith" (and Mr Smith for men), preferring to use names. Some shifted to "Ma'am" to refer to female teachers, based on how one would refer women of higher rank (in the army, for example). This is part of the culture of the school.

In general, outside of school, avoid "Ma'am" (and Sir). In business (for example) you should get to know people's names, and then use their names. It is reasonable to ask for someone's name if you are in a business meeting. In casual meetings (asking directions for example) you would not normally need names, or titles. If that is impossible to avoid (for example as a shop assistant speaking to a customer) you may use "madam" and "sir". And if you meet the queen, use "your majesty" at first, and "ma'am" on subsequent occasions.


@StoneyB and @Willow Rex have offered some useful observations.

I would like to add a few other points:

In my experience, in the US it is still generally considered polite, and largely obligatory, whether in the South or outside the South, for anyone representing a business establishment or a government office to address a customer or member of the public whose actual name the worker does not know as "sir" (for men) or as "ma'am" (for women). This applies to servers in restaurants, desk attendants in hotels, flight attendants and other airline staff, company customer service representatives answering telephone calls, police officers, clerks in government agencies, etc.

This also applies to interactions between adults who do not know each when one is trying to attract the attention of another in a public space, such as while riding on a bus, while waiting in a queue when shopping or when entering a business, etc.).

It is considered extremely rude to try to get someone's attention by saying something like "Hey, you," or "Hey, lady," rather than "Excuse me, ma'am."

("Madam" is very rarely used in spoken English. It is generally considered extremely formal and old-fashioned.)

Younger women and girls are still usually addressed in these situations as "miss" rather than "ma'am," while older women are addressed as "ma'am." There is no absolute rule for when a woman is too old for "miss" and should be addressed instead as "ma'am." (I was taught years ago that you should use "ma'am" for any woman who is old enough to be a mother. lol)

  • For what its worth, I grew up in the southern part of the US and was trained from an early age to address everyone older than me as "sir" or "ma'am". This then extended to almost everyone over time. I'm in my 50s now and still do it as a habit. It just seems polite.

As a counterpoint to the other examples: While there are many situations and locations where the use of "ma'am" is common and appropriate, having lived in California for most of my life I can't recall even one instance where I used it as it is meant to be used. It can be said by those in service or retail jobs where they are expected to show politeness and deference to the customer -- the more "upscale" the business, the more likely they will use "sir" and "ma'am".

But it is not normal in casual conversation, so much so that when I met a young man who punctuated every sentence with "sir" or "ma'am", his good manners seemed extraordinarily and almost uncomfortably archaic.

Which isn't to say that young people here are rude and don't use any honorifics. Instead it's more common to call someone my their name, "Mr. Jones", "Mrs. Smith", etc.

Anyway, I'm now at an age where I am (from time to time) called "sir" -- which, as others have pointed out, makes me feel old. So I would never call someone else "ma'am", lest they feel that I was implying they are even older than I am.

    If you happened to live near a military installation in the U.S., you might hear quite a few young people in the community using those "uncomfortably archaic" manners you speak of. Most of them would look quite fit and strong, and the males would have neatly trimmed short hair. They might even call the waitress ma'am. Yes, sir, they just might do that.
