You’re staring at the board. The clock is ticking, or maybe you’re just sitting on the sofa with a cup of coffee, desperately trying to keep your Wordle streak alive. You have an X. It’s a high-value tile, worth a solid 8 points in Scrabble, but it feels like a curse when you can't find a place to dump it. Most people think "Xylophone" or "X-ray," but those are long. You need something short. Specifically, you need 3 letter words starting with x.
Honestly, there aren't many. English is weird like that. We borrowed a lot of our X-words from Greek, and they usually come with a trail of other letters behind them. But if you’re playing competitively, knowing the few that exist is basically like having a cheat code.

The Absolute Essentials: Xis and Xap
If you only memorize one thing today, make it XIS.
It’s the plural of xi. In the Greek alphabet, xi is the fourteenth letter. It’s pronounced like "ksy" or "zy," depending on how much of a linguistics nerd you want to be at the dinner table. In Scrabble, XIS is a lifesaver. It lets you use that X on a double or triple letter score while hooking onto an existing S. It’s legal in the Official Scrabble Players Dictionary (OSPD) and the SOWPODS list used internationally.
Then there’s XAP. This one is trickier.
You won't find XAP in your standard Merriam-Webster, and it’s generally not accepted in tournament Scrabble. It’s a unit of currency, specifically related to the Lao kip in some older financial contexts, but for the most part, stay away from it in games unless you’ve agreed on a very loose dictionary. Stick to XIS.
Why Are There So Few X Words?
It’s a fair question. Why is the letter X such a loner at the start of words?
Most English words starting with X are Greek in origin. Think xeno (foreign) or xylo (wood). Because these are prefixes, they almost always attach to longer roots. The "short" versions just didn't survive the transition into common English usage. We ended up with a language where X is common at the end of words (box, fix, tax) but incredibly rare at the beginning.
The Crossword Favorite: Xeb
Every now and then, you might see XEB pop up in a niche word list. It’s a shorthand or variant related to xebec, which is a small, three-masted Mediterranean sailing ship. However, most dictionaries—and certainly the ones used by the North American Scrabble Players Association (NASPA)—require the full spelling.
If you're playing a casual game and someone tries to play XEB, you’re well within your rights to challenge it. Unless you’re feeling generous. But who plays Scrabble to be generous? You play to win.
The Strategy of the X Tile
Don't just throw the X away.
Since there are so few 3 letter words starting with x, your best bet is often to play the X at the end of a word or in the middle. Think about words like AXE, LEX, or REX. But if you are stuck with a board where the only opening is a three-letter slot starting with X, you are almost certainly looking for XIS.

Wait. There is another.
XEN. You’ll see this in some dictionaries as a variant or a specific brand/technological term (like the Xen hypervisor in computing), but it’s not a standard Scrabble word. In the world of gaming and tech, Xen is a massive name, but in the world of linguistic competition, it’s a ghost.
Dealing with the "Is it a Word?" Frustration
We've all been there. You play a word, someone sneers, and out comes the dictionary.
The problem with 3 letter words starting with x is that many of them are "incidental" words. They are symbols, abbreviations, or prefixes that haven't quite made the jump to "standalone word" status. For example, X-Y-Z is a common phrase, but XYZ isn't a word. X-ray is a word, but XRA isn't.
Common "Fakes" to Avoid:
- XAT: You’ll see this in some very old lists. It refers to a carved totem pole used by indigenous peoples of the Pacific Northwest. While it's a real term in ethnography, it’s not in the OSPD.
- XIS: (Wait, this one is real. Use it.)
- XOR: This is a logic gate term in computer science (Exclusive OR). While it’s a real word to programmers, it only recently started gaining acceptance in mainstream word lists. Check your specific game’s dictionary before trying this one.
Professional Tips for Word Games
If you want to actually improve your score, stop hunting for the elusive 3-letter X word that probably doesn't exist and start looking for "hooks." A hook is a single letter you can add to an existing word to make a new one.

If someone plays IS, you drop that X in front to make XIS.
If you’re playing a game like Wordle, the X is almost never at the start. It’s usually at the end (INDEX, RELAX, ADDOX) or in the fourth position (EXTRA, SIXTY). Don't waste your guesses putting X in the first slot unless you’re absolutely certain.
The Cultural Impact of the Letter X
X is the "cool" letter. It represents the unknown. It represents the "X-factor."
In the 1990s, brands obsessed over the letter X. It was edgy. We had the X-Games, the X-Files, and Generation X. But even with all that cultural weight, we didn't actually create many new short words for it. We just used it as a symbol. This is why, when you're playing a word game, you feel like there should be more options. There aren't. You're fighting against centuries of linguistic history that preferred "S" and "T" and "A."
Actionable Steps for Your Next Game
Stop guessing. If you want to master the high-value tiles, you have to be surgical.
- Memorize XIS. It is your only consistent friend in the 3-letter X category for Scrabble.
- Verify XOR. If you’re playing online or with modern "unabridged" rules, XOR might be your secret weapon.
- Check the "S" Hook. Always look for an "IS" already on the board.
- Forget XAT and XEB. Unless you are playing with a 19th-century dictionary or a very confused sailor, they won't pass a challenge.
- Pivot to 2-letter words. If you can't make a 3-letter word work, remember that XI and XU (a Vietnamese currency unit) are both legal and much easier to place.
By focusing on these specific, verified terms, you stop bleeding points and start putting pressure on your opponents. The X isn't a burden if you know exactly where it belongs.
