Ever stared at a Scrabble rack with an 'X' and felt that slow creep of panic? It's a common vibe. You’ve got a high-value tile, but your brain is basically a blank screen because, honestly, how many words actually start with X? Most people think of X-ray and then just... stop. But if you’re trying to win a word game or just want to stop being intimidated by the end of the alphabet, you need to know the 3 letter words starting with X. There aren't many. In fact, in standard English dictionaries like Merriam-Webster or the Official Scrabble Players Dictionary, we are looking at a very exclusive club.
The big three: Xeb, Xis, and Xan
Let's get the heavy hitters out of the way first. When people search for 3 letter words starting with X, they are usually looking for game-legal plays.

Xis is the plural of xi. In the Greek alphabet, xi is the 14th letter. It’s pronounced like "ksye" or "zee," depending on how much of a linguistics nerd you want to be. If you're playing Scrabble or Words with Friends, "xis" is a literal lifesaver because it uses that high-point X and a couple of very common vowels/consonants. It's the kind of word that makes your opponent think you've swallowed a dictionary.
Then there is Xeb. Now, this one is a bit more obscure. It is a shorthand or variant related to "xebec," which is a small, three-masted Mediterranean sailing ship. You don’t hear it much at the grocery store. It’s a bit archaic. But in the world of competitive word play, knowing "xeb" can turn a dead-end turn into a 20-point lead.
What about Xan? This one is tricky. In some slang dictionaries or specific cultural contexts, Xan refers to Xanax. However, you’ve got to be careful. Most official word game dictionaries—like the one used by the NASPA (North American Scrabble Players Association)—don't allow it because it’s often considered a proprietary name or a clipped form of a trademark. Still, in casual play or if you’re just looking at how language evolves, "xan" is definitely in the public consciousness.

Why the letter X is so rare in English
It’s kind of a historical accident. English is a Germanic language with a massive amount of Latin and French grafted onto it. In Old English, we didn't really have a lot of use for the 'X' sound at the start of words. Most of our 'X' words come from Greek. Think about it: xylophone, xenon, xerox.
When you look for 3 letter words starting with X, you’re fighting against centuries of linguistic evolution that preferred 'S' or 'Z' sounds. This is why "Xis" is so vital. It’s a direct gift from the Greeks. Without that influence, your 'X' tile would be even more of a nightmare.
Beyond the dictionary: Slang and tech
If we move away from the rigid rules of the Scrabble board, the list of 3 letter words starting with X starts to grow, but it gets a bit "wild west."
- Xat: This refers to a carved totem pole among certain Indigenous peoples of the Pacific Northwest. It’s a real word. It’s specific. It’s beautiful. It is also often missing from smaller dictionaries, which is a shame because it’s a great piece of cultural history.
- Xen: You see this in technology all the time. Xen is a famous open-source hypervisor. It’s the tech that lets multiple operating systems run on the same hardware. If you’re a dev, "xen" is a daily word. If you’re a poet, maybe not so much.
- Xes: This is the plural of the letter X. "He marked the map with three xes." Simple. Effective. Totally legal in most games.
The "X" strategy you’ve probably been ignoring
Honestly, the goal shouldn't just be memorizing the words. It's about placement. Because the 'X' is worth 8 points in Scrabble, playing it on a double or triple letter score is the difference between a mediocre game and a blowout.
Most players wait for a long word like "Excite" or "Taxation." That is a mistake. You’re holding onto that tile, clogging up your rack, waiting for a miracle. Instead, look for the "hook." If there is an 'I' on the board, drop your 'X' next to it to make "XI." If you can do that and start a new word vertically, you score the 'X' twice.
Knowing 3 letter words starting with X like "Xis" allows you to play from the 'X' rather than just trying to dump it at the end of something else. It gives you agency.
Why "Xoy" and "Xub" aren't things
You'll see weird lists online. People love to make things up to get clicks. They’ll tell you "Xoy" is an ancient fish or "Xub" is a type of dirt. It’s fake. There is no reputable English dictionary that recognizes them. Stick to the verified stuff. The frustration of having a word challenged and losing your turn is way worse than just playing a 2-point word and moving on.
Practical tips for word game mastery
- Memorize XIS and XES immediately. They are your bread and butter.
- Look for the Greek roots. If you see a word like "Xi," remember that the plural is almost always "Xis."
- Don't fear the "X". It’s a gift, not a burden.
- Check your dictionary version. If you're playing digitally, the game usually uses the Merriam-Webster Scrabble Dictionary. If you're playing a physical game, agree on the "source of truth" before you start. It saves friendships.
The reality of 3 letter words starting with X is that the list is short, but the impact is huge. You don't need a massive vocabulary to be effective; you just need to know the specific keys that unlock the board. Next time you see that 'X', don't groan. Look for the 'I' or the 'E' and drop "Xis" or "Xes" like a pro.

To actually improve your game, start by practicing "parallel plays." This is where you place a short 'X' word parallel to another word already on the board, so that every letter of your new word forms a small, 2-letter word with the letters above or below it. This can easily turn an 8-point 'X' into a 30-point turn without needing a long, complex word.
Actionable Next Steps
- Verify your lexicon: Open your preferred word game app and check if "XAT" or "XEB" are accepted in their specific dictionary, as some apps use different databases (like SOWPODS vs. TWL).
- Flashcard the "Big Three": Write down XIS, XES, and XEB. Keep them in your mind as your primary escape routes for high-value tile situations.
- Scan the board for 'I' and 'E' hooks: In your next game, don't look for where to put the 'X'. Look for where an existing 'I' or 'E' is positioned near a bonus square, then work backwards to see if XIS or XES fits.
