NM in a text usually means either 'not much' or 'never mind'. Dictionary.com lists nm as internet slang for both. The quick way to tell them apart is what came before it: after 'what's up?' it means not much, and after a half-finished question it means never mind, forget I asked.
Two letters, two very different meanings. NM is one of those abbreviations that changes completely depending on where it lands in a conversation. Get it wrong and you'll either think someone's brushing you off or wonder why they've gone quiet. Here's how to read it every time.
Not much: the answer to 'what's up?'
Wiktionary lists one use of nm as short for 'not much' or 'nothing much'. Its example is the classic exchange: 'hey', 'hey, sup?', 'nm u?'. That's someone saying they're not up to anything special and turning the question back to you.
There's even a longer version. Wiktionary records nmu as 'not much, you?', which does the same job in three letters instead of a full sentence. If you get 'nm' on its own, it often still carries that 'and you?' feeling, so a reply about your own day keeps things moving. It works a lot like WBU, just from the other direction.
Never mind: when someone drops the subject
The second use is an interjection: nm as 'never mind'. Wiktionary gives nvm as a synonym, and its example shows someone starting a question, the other person replying 'huh?', and the first person sending 'nm, that was a mistake'.
This version means 'forget it'. Maybe they worked out the answer, sent the message to the wrong chat, or decided the question wasn't worth it. It's rarely rude, though a sudden 'nm' after a long pause can feel like a door closing. If you want to know what they were going to ask, a light 'go on, what was it?' usually does the trick.
Reading the clue in the message before
| What came before | What NM means | Natural reply |
|---|---|---|
| 'What's up?' or 'wyd?' | Not much | Share what you're up to, or ask a question back |
| A question they abandoned | Never mind | A quick 'all good', or 'what was it?' |
| 'Huh?' or 'what do you mean?' | Never mind, forget it | Let it go, or ask once |
| A list of options | Not much of a preference, sometimes | Pick one for them |
That third row trips people up. If you reply 'huh?' and get 'nm', they're usually not annoyed. They've decided it's easier to drop it than explain.
No message, and why it's rare
Wiktionary records a third, much rarer meaning: nm as 'no message'. You'll mostly see it in older contexts, like a subject line or note where the content is the point and nothing else needs saying. In everyday texting you can almost ignore it.
NM outside your phone
Search for NM and you'll hit plenty of meanings that have nothing to do with chat. Dictionary.com lists these:
- nm as the symbol for a nanometre, a billionth of a metre, used in science and chip manufacturing.
- N.M. or NM as the abbreviation for New Mexico, including the postal code.
- Nautical mile, though Wiktionary flags that using nm for it clashes with the nanometre symbol.
- In grammar, a short form of noun modifier.
Wiktionary's uppercase NM entry adds two that come up a lot online: 'near mint', the condition grade collectors use for cards, comics and records, and 'not meaningful' in reports and tables. In athletics, NM is also short for a no-mark, when an athlete records no valid attempt. If you're browsing a trading card listing, NM almost certainly means near mint, not 'not much'.
These are made-up texts to show the two main meanings, not real chats:
- 'Hey what's up?' 'Nm, just got home, u?' Not much.
- 'Did you see the... nm, found it.' Never mind.
- 'Nm really, just tired.' Not much going on.
- 'Wait which time is it, nm I'll check.' Never mind, I'll sort it.
Why NM can feel like a brush-off
Because nm can mean 'not much', a reply of just 'nm' to 'what's up?' can come across as low effort. It answers the question but gives nothing back, so the chat has nowhere to go. If you're keen to keep talking, 'nm, you?' or Wiktionary's nmu form hands the conversation back.

The 'never mind' version has its own trap. If someone sends a question, waits, and then writes 'nm', they may feel ignored. A quick 'sorry, missed this, what did you need?' fixes that straight away. Most of the time, though, nm is just people being efficient, and there's no hidden message to decode.
Capital letters don't change the meaning much in chat. 'NM' and 'nm' are used the same way, though all caps can look a little louder. In listings and reports, capitals are more common, which is another hint that you're looking at near mint or not meaningful rather than slang.
A last tip for group chats: if several people are talking and someone drops an 'nm', check who it's aimed at. In a busy thread, it often means 'never mind, someone already answered', which is a good thing. It saves everyone from repeating the same reply, and it shows the sender has been reading along rather than just posting. If you were the one about to answer, a thumbs-up reaction is a tidy way to show you've seen it.
Using NM with customers and colleagues
With friends, nm is perfectly natural. In work chat it's fine for a quick 'nm, sorted it' to a colleague. With customers, I'd spell it out. 'Not much' can read as uninterested, and 'never mind' from a business can sound dismissive, as if their question didn't matter. A full line, such as 'Ignore that last message, I've found the answer', reads warmer and avoids confusion. If you sign off for the day, a short yh or 'speak tomorrow' keeps the tone friendly.
