Honestly, staring at a rack in Scrabble or a blank Wordle grid and seeing that "X" staring back at you is enough to trigger a minor panic. It’s a high-value letter, sure, but it feels clunky. Most of us immediately think of X-ray or Exams, but when you’re restricted to that specific five-letter length, the brain tends to freeze up. You’ve probably been there—three minutes left on the timer, your opponent is smugly waiting, and you’re convinced that "X" is going to be your downfall. It’s not. In fact, knowing a handful of 5 letter words with x in them is basically like having a secret weapon that most casual players completely overlook.
The "X" is worth 8 points in Scrabble for a reason. It’s rare. But in the world of competitive word games, rarity is an opportunity, not a handicap.
Why 5 letter words with x in them are actually game-changers
If you’ve played Wordle recently, you know the developers love to throw a curveball. We aren't just talking about common vowels anymore. We’re talking about words like Epoxy or Axial. These aren't just filler; they are strategic hurdles. When you use 5 letter words with x in them, you are filtering out a massive portion of the alphabet in one go.
Think about the word Proxy. It’s common enough that you know what it means—someone acting on behalf of another—but it’s structurally weird for a word game. It’s got that "P" and "R" start, but the "X" and "Y" ending is a nightmare for people guessing blindly. If you drop Proxy as a second or third guess in Wordle, you’ve instantly checked for two of the most difficult letters in the English language.
Then there’s the sheer scoring power. In games like Words With Friends, landing an "X" on a Triple Letter score can swing a game by 50 points in a single turn. You don't need a 7-letter bingo to win. You just need to know where to tuck a Silex or a Borax.
The "X" at the beginning vs. the end
Most people instinctively look for words where "X" is in the middle, like Fixed or Taxed. That’s fine. It’s safe. But if you want to actually win, you need to look at the outliers.
Take Xenon. It’s a noble gas. It starts with an "X". Most people don't even realize there are five-letter words starting with "X" beyond the obvious Xylos (which is technically a prefix but allowed in many dictionaries as a plural shorthand). Using Xenon or Xeric—a term used in ecology to describe an environment with very little moisture—can absolutely dismantle an opponent’s strategy because they aren't looking at that first column.

On the flip side, ending with "X" is a classic power move. Tableaux? No, that’s too long. We’re looking for Relax, Detox, or Annex. These are the bread and butter of the 5 letter words with x in them category. They are "safe" words. They use common vowels like "E" and "A," making them easy to slot into a board that is already crowded.
The Weird Ones: Words you’ve never heard of but need to know
Let’s get nerdy for a second. If you really want to master 5 letter words with x in them, you have to memorize the "weird" ones. These are the words that make people accuse you of cheating.
- Silex: This is basically finely ground flint or silica. It’s a killer word because "S" and "I" are so common.
- Ixora: A genus of flowering plants. If you can land this on a board, you’re playing at a pro level.
- Oxter: This is a brilliant bit of dialect from Scotland and Ireland meaning "armpit." It’s a perfectly valid Scrabble word.
- Zaxes: The plural of "zax," which is a tool for cutting roof slates. It uses a "Z" and an "X." That is a massive point haul.
- Exurb: A region beyond the suburbs. It’s a great way to use that "U" which often sits rot on your rack.
The trick isn't just knowing they exist. It's knowing when to burn them. You don't hold onto an "X" waiting for the perfect spot. You use it the moment you can secure a 20+ point lead or narrow down a Wordle solution.
Breaking down the patterns
If you analyze the frequency of 5 letter words with x in them, you start to see patterns. The letter "A" is the "X's" best friend. Abrax, Antix, Axils, Relax, Taxol. If you have an "A" on your rack and an "X," your chances of finding a valid five-letter move jump significantly.
What about the "E"? You’ve got Exult, Exert, Excel, and Eject... wait, no "X" there. See? Your brain wants to group high-value letters together. You have to be disciplined. Exile is a fantastic word because it uses "E" twice and an "I." It’s a vowel-heavy word that clears your rack and keeps your options open for the next turn.
Misconceptions about "X" words
A lot of people think that words with "X" are always scientific or Latin-based. That’s a trap. While Helix and Oryx (a type of antelope) definitely fit that mold, many are just everyday verbs or nouns we use without thinking. Mixed, Boxer, Texas (though usually capitalized and thus illegal in Scrabble, it's often a valid guess in other word games), and Sixth.

Sixth is actually one of the hardest words for people to guess in Wordle-style games because of the "S-I-X-T-H" construction. It feels like it should be longer. It feels like it shouldn't have that "H" at the end.
Another misconception? That you need a "Y" to finish an "X" word. Sure, Epoxy and Proxy are great. But don't forget Toxol or Taxon. A "Taxon" is just a taxonomic group. It’s a boring word for a very exciting amount of points.
Strategic placement in word games
When you’re looking at a board, don't just look for where the "X" fits. Look for where the "X" blocks. Because 5 letter words with x in them are often structurally unique, they can be used to "cap" a Triple Word Score so your opponent can’t reach it.
If you play Admix (to mix something in), you are using five letters, but you are also creating a wall. The "X" is a hard letter to build off of. Unless your opponent has a vowel to create Ox or Ex, they are stuck. You’ve effectively neutralized that section of the board.
List of high-utility 5 letter words with x in them
Instead of a boring list, let’s look at these by how they actually function in a game.
The Vowel-Heavy Saviors
These are for when your rack is a mess of A, E, I, O, U and one lonely X.

- Adieu (Wait, no X). Let's try Audio... no.
- Axiom: Uses A, I, and O. It’s the ultimate "clean my rack" word.
- Ouija: No X. But Auxin (a plant hormone) is the one you want. A, U, I.
- Oxide: O, I, E. Simple, effective, devastating.
The Consonant-Crunchers
These help when you have no vowels.
- Lynx: The "Y" acts as the vowel. Very hard to play against.
- Pyrox: Part of a mineral name. Another Y-as-vowel play.
- Xysts: Plural of xyst, an ancient Greek covered portico. Almost no vowels here.
The Everyday Reliables
- Extra
- Index
- Toxic
- Maxim
- Vixen
How to actually get better at this
Memorization is part of it, but visualization is better. Stop looking for the "X" in the middle. Start looking at your vowels and seeing if an "X" can be the bridge.
If you have an "O" and an "I," can you make Toxic?
If you have an "A" and an "E," can you make Taxed?
The best players aren't the ones who know the most words; they are the ones who recognize the shapes of words. 5 letter words with x in them have very distinct shapes. They often have a "spiky" look to them—lots of ascenders and descenders like "p," "y," "f," and "x."
Actionable steps for your next game
To truly master 5 letter words with x in them, you need to change how you practice. Most people just play and hope for the best. Don't do that.
- Open a blank Wordle-style grid and try to come up with five words containing "X" without looking at a dictionary. If you can't hit five in under a minute, you need to broaden your vocabulary.
- Focus on the "X" at the end. Practice finding spots for Annex, Infix, and Unfix. These are surprisingly common in board games because they allow you to build off existing prefixes.
- Learn the "XI" words. In Scrabble, "XI" is a valid 2-letter word. Knowing 5-letter words that incorporate this—like Exile or Exist—allows you to play parallel to other words on the board, doubling or tripling your score.
- Watch the "Y". If you have an "X" and a "Y," you should almost always be looking for Epoxy, Proxy, or Myxon.
The "X" tile is a gift, not a curse. The next time you see it, don't try to get rid of it as fast as possible. Look at the board. Look at your 5-letter options. If you can drop Axiom or Silex, you aren't just playing a word—you're winning the game.
