In notes and texts, an X means a kiss, an O means a hug, and a row of Xs sends extra kisses.
You’ve seen it at the end of a text, a card, or a DM: “x” or “xx” or “xoxo.” It feels friendly, but the meaning can get fuzzy fast. Is an X a hug? Is it a kiss? Does “x’s” change anything?
Here’s the plain read that most people follow: X = kiss and O = hug. A single X is one kiss. Two Xs are two kisses. An O is a hug. Mix them and you’re sending both.
Still, there’s a catch: people also use Xs as a warm sign-off with no romantic angle at all. So the symbol is simple, but the vibe comes from who sent it, your relationship, and the rest of the message.
Are X’s Kisses Or Hugs? Meaning In Messages
In everyday messaging, X’s are kisses. If someone writes “x” at the end of a text, they’re sending a kiss the same way they might sign a note with “love” or “take care.” If they write “xx,” it’s usually “two kisses,” not “two hugs.” Hugs are shown with O’s.
That’s why “xo” is read as “hug and kiss,” and “xoxo” is read as “hugs and kisses.” You’ll also see “xxx” used as a stronger kiss sign-off, common in casual messages between close friends, partners, or family members who already talk that way.
When people say “sending x’s,” they mean “sending kisses.” When they say “sending o’s,” they mean “sending hugs.” Put together, “sending x’s and o’s” is the full package.
What X And O Actually Stand For
X stands for a kiss. Think of it as a stamped mark of affection at the end of a note. Some people also link it to the shape of a kiss mark (a crisscross), but you don’t need a theory to use it. In modern texting, it’s a kiss.
O stands for a hug. The circle can feel like arms wrapped around someone. In practice, it’s the “hug” symbol, even if someone has never once thought about why the letter looks like that.
If you want a fast mental check, remember this: kisses land as “x” sounds when you say the letter out loud (“ex”), and hugs feel round and enclosing, like an “o.”
Where This Comes From And Why It Stuck
The “X means kiss” idea shows up in writing long before texting. Over time, it settled into a common sign-off shorthand. “XOXO” then became a tidy way to send affection without typing a full sentence.
Language references that track usage treat “XO” and “XOXO” as a standard sign-off meaning “hugs and kisses.” If you want a quick background read that matches current use, Dictionary.com’s explainer on XOXO meaning and origin lays out how X = kiss and O = hug in modern messages.
You may also see older notes where both X and O were used as kiss marks in some settings. Modern texting still lands on the same shared code most of the time: X for kisses, O for hugs.
How Many Xs To Use Without Making It Weird
There’s no universal rule, but there are common patterns. One X is light. Two Xs are warmer. Three Xs can read flirty or intimate, depending on who’s sending it. Long strings of Xs can feel playful between close people, or feel like overkill with someone you don’t know well.
Context does the heavy lifting. A coworker texting “Thanks, x” can read as friendly if you already talk that way, but it can also feel off in a formal work thread. A close friend adding “xx” at the end of a message can feel normal if that’s your usual tone.
If you’re unsure, match the other person’s level. If they sign with one X, reply with one X. If they never use Xs or Os, you can skip them and still sound warm by writing a friendly closing line.
How To Read Xs When You’re Not Sure What They Meant
If the sender is family, a long-time friend, or a partner, Xs nearly always mean kisses. If the sender is new, the meaning can slide from “kiss” into “friendly sign-off.” That isn’t a contradiction. It’s the same symbol doing two jobs: affection and warmth.
Use these quick cues:
- Who sent it: Partners and close friends use Xs as kisses more often.
- Where it appeared: End-of-message Xs act like a sign-off.
- What else was said: A flirty line plus “xx” is a stronger kiss signal than a plain “ok x.”
- Your usual pattern: If they always add Xs to everyone, it’s their default warmth setting.
If you’re still stuck, treat a single X as friendly warmth, not a confession. You can reply warmly without mirroring the X until you see a pattern.
X’s Vs Xs: The Grammar People Notice
This is where many writers pause. When you mean “more than one X,” you’re writing a plural. In many styles, the clean plural is Xs. Still, apostrophes show up with single letters because they improve readability, especially in lowercase. Some style guides allow x’s and o’s for that reason.
Chicago’s style Q&A notes that apostrophes are used for plurals of lowercase single letters like x’s and o’s, while most other plurals don’t take an apostrophe. If you write for a publication, follow its style. If you write for yourself, pick one approach and stay consistent.
In plain texting, people often type “x’s” because it looks clear and familiar. In polished writing, “Xs” is common when the letters are uppercase. Either way, readers will understand you if the sentence is clear.
One more point: X’s can also be possessive, meaning “belonging to X.” That’s rare in this context, but it’s why some people avoid apostrophes in plurals and write “Xs” instead.
If you’re writing a sentence like “She ended the note with three Xs,” that’s clean and hard to misread.
Government style guidance also calls out single-letter plurals as a spot where an apostrophe can help clarity, with examples like 0’s and 1’s. See the Australian Government Style Manual page on apostrophes for letter plurals for that rule framing.
So, does “X’s” mean kisses or hugs? In meaning, it’s kisses. In grammar, it’s a plural form many people use for the letter X, even though some styles prefer “Xs.”
Common X And O Patterns People Use
People don’t only send a single X or a full “xoxo.” They mix and match. Here’s how these patterns are usually read when they show up at the end of a message.
| Pattern | Usual Meaning | When It Fits Best |
|---|---|---|
| x | One kiss | Light sign-off with someone you know well |
| xx | Two kisses | Warm, friendly closing for close friends or family |
| xxx | Three kisses | More intimate tone, often partners |
| xo | Hug + kiss | Affectionate sign-off without a long message |
| xoxo | Hugs + kisses | Cards, sweet texts, close relationships |
| o | One hug | Comforting sign-off, gentle tone |
| oo | Two hugs | Extra warmth without kisses |
| ox | Hug + kiss | Same meaning as xo, just flipped order |
When Xs Can Cause Mixed Signals
Xs are simple with friends and family. The confusion shows up when the relationship is new, or when the setting is formal. A single X can feel like a casual kiss sign-off to one person and feel like a standard friendly closer to another.
These are the moments where it can land wrong:
- Work chats: If your team never uses Xs, adding one can feel too personal.
- New acquaintances: One X can be read as flirting, even if you meant “thanks.”
- Uneven patterns: If one person sends “xxx” and the other sends none, it can feel awkward.
If you want warmth without any chance of mixed signals, use words: “Thanks so much,” “Talk soon,” “Take care.” That gives the same friendly tone with less decoding.
How To Reply If Someone Sends You Xs
You don’t need to mirror the exact number of Xs to be polite. You can match the vibe in a few ways:
- If it’s a close friend or partner and you’re comfortable, mirror it: x for x, xx for xx.
- If you’re unsure, reply warmly with no Xs once, then see what they do next time.
- If you want to keep it friendly and clear, use an O for a hug or write “hug” in words.
In a new thread, you can also split the difference with “xo” if that feels right for your relationship. If it doesn’t, skip the symbols and keep your closing friendly with words.
Writing It Cleanly In Cards, Captions, And Longer Notes
In a card or caption, people often write “XOXO” in uppercase because it looks like a set phrase. In that setting, “X’s and O’s” can show up as a cute line too. If you’re writing a polished note and you want the plural letters, “Xs and Os” is a clean option.
If you want to mention the convention in a sentence, keep it direct:
- “I signed the card with XOXO.”
- “She ended the message with a few Xs.”
- “They texted xo before boarding.”
If you’re explaining the meaning to someone, a short reference is enough. Quick-and-Dirty Tips has a plain-language piece on why XOXO means hugs and kisses that matches how most people read it today.
Quick Checks Before You Add Xs
These checks keep you from sending the wrong signal:
- Match the channel: A card between friends can take “xoxo.” A work email usually can’t.
- Match the relationship: Close friends and family often expect Xs. New contacts may not.
- Match the tone: A serious message plus “xxx” can feel off. A warm message plus one X can fit.
- Match your usual voice: If you never use Xs, adding them can feel forced.
And if you’re writing the plural form in a longer piece, pick “Xs” or “x’s” based on the style you follow, then stick with it across the page.
| What You Want To Write | Best Form | Why It Works |
|---|---|---|
| More than one X (uppercase) | Xs | Clear plural in most modern styles |
| More than one x (lowercase) | x’s | Readable in styles that allow apostrophes for letter plurals |
| Hugs and kisses sign-off | XOXO | Recognized phrase form in cards and captions |
| Light kiss sign-off | x | Short, friendly, easy to match |
| Warm hug sign-off | o | Gives comfort without a kiss signal |
| Talking about the symbols in a sentence | Xs and Os | Readable and common in general writing |
| Avoiding any mixed signal | Use words | No decoding needed by the reader |
The Simple Takeaway You Can Trust
If you came here for one clear answer, it’s this: X’s are kisses, O’s are hugs. That’s the shared code behind “xo” and “xoxo.” The rest is just tone and context.
If you’re writing “X’s” in a sentence, you’re almost always talking about multiple kisses or multiple X marks as a sign-off. If you’re writing in a more formal style, “Xs” is often the cleaner plural for the letter. Either way, readers will get you if you keep the sentence clear.
Send one X when you want a light kiss. Send O when you want a hug. Send both when you mean both. And when the setting is formal, skip the symbols and write the warmth in plain words.
