All 2-Letter Words

All 96 Valid 2-Letter Words

Two-letter words are the backbone of Scrabble and Words With Friends strategy. They let you play parallel words and squeeze extra points out of a tight board. Here is the complete list from our ENABLE dictionary:

Why 2-letter words matter

Knowing all valid 2-letter words lets you hook new words onto existing tiles on the board without wasting a turn. Words like QI, XI, and ZA are especially valuable since they use high-point letters in a short, easy-to-place word.

Why This Is the Highest-Value List in Word Gaming

If you only ever memorize one word list, make it this one. Ninety-six words is an evening's work, and it changes your game more than learning a thousand seven-letter words would.

The reason is parallel play. In Scrabble and Words With Friends, you can lay a word alongside an existing word instead of perpendicular to it, and when you do, every tile you place forms a second word in the crossing direction. Each of those crossing words scores on its own. A four-tile parallel play can form four two-letter words at the same time, and you collect points for all of them plus your main word. This is where the big scores live, and it is completely unavailable to a player who does not know the two-letter list, because you cannot risk a play when you do not know whether the crossings are legal.

The second reason is hooks. Every two-letter word is a place where a single tile can be added to something already on the board. The same trick runs one letter longer on the three letter list. Knowing that AX, EX, OX, XI, and XU are all valid means an X tile is never stranded. Knowing JO exists means a J has somewhere to go. These are the escape hatches that keep expensive tiles from sitting dead on your rack.

The Shape of the List

Ninety-six words sounds like a lot until you see the structure. Forty-nine of them start with a vowel and forty-six end with one. Only four are made of two vowels: AA, AE, AI, and OE. Only five contain no A, E, I, O, or U at all: BY, HM, MM, MY, and SH.

The vowel-initial groups do most of the work. A gives you 16 words, O gives you 12, E gives you 10, U gives you 6, and I gives you 5. That is 49 words in five clusters, and those clusters are the ones you will actually reach for, because vowels are the letters most likely to already be sitting on the board when you need a hook.

Learn them in that order. The sixteen A words first: AA, AB, AD, AE, AG, AH, AI, AL, AM, AN, AR, AS, AT, AW, AX, AY. Then the twelve O words: OD, OE, OF, OH, OM, ON, OP, OR, OS, OW, OX, OY. Then the ten E words: ED, EF, EH, EL, EM, EN, ER, ES, ET, EX. Those three groups alone are 38 of the 96, and between them they cover the overwhelming majority of real hook situations.

The Ones That Look Wrong But Are Not

A good half of this list will look invented to someone who has not played competitively, and that reaction is the single biggest reason casual players lose points. These are the words worth understanding rather than just memorizing, because understanding them makes them stick.

AA is a type of rough, jagged lava, from Hawaiian. It is one of the most useful words in the game because it dumps two A tiles at once. AE is a Scots form of "one." AI is the three-toed sloth. OD is a hypothetical natural force from nineteenth-century pseudoscience. OE is a whirlwind off the Faroe Islands. OS is a bone or an opening. EF, EL, EM, EN, AR, ES, and PE are letter names spelled out, which is a whole family: once you know that letter names count, several entries stop looking arbitrary. UT is the old name for the musical note now called do. XU is a Vietnamese monetary unit. KA is the spirit in ancient Egyptian belief. NU, PI, MU, XI, and ET come from Greek.

The sound words are their own group and the ones people challenge most often: HM, MM, SH, AH, EH, OH, UH, AW, OW, OY, HA, HE, HI, HO. All legal. HM and MM are especially valuable because they contain no vowel at all, which makes them the answer when your rack is all consonants and you need to shed something.

A Note on Which Dictionary You Are Playing

The list above is the conservative core, the set that is valid across the common tournament dictionaries. Newer editions of the North American list, NWL, and the international list, CSW, have both added words since. The two additions worth knowing about are QI and ZA, because they are the highest-value short words in the modern game: QI lets you play a 10-point Q with no U at all, and ZA does the same for a Z.

If you play in a club or a tournament, check which edition is in use before you rely on either. To settle a single word rather than read a whole list, check it here and see what it scores in both games. If you play at home or on an app, the app's dictionary decides, and the fastest way to find out is to try the word once and see whether it is accepted. Most disputes about two-letter words are really disputes about which edition someone learned, not about whether a word is real.

Turning the List Into Points

Memorizing the words is step one. Using them is step two, and there are three patterns that convert knowledge into score.

The premium-square hook. Look for a Double or Triple Letter square adjacent to an existing word. If you can place a high-value tile there so it forms a legal two-letter word, you collect the multiplier on your best tile for the cost of one tile. An X on a Double Letter forming both XI and a second crossing word is 32 points from a single tile.

The parallel run. Find a word on the board with open space beside it. Lay your word alongside so each of your tiles pairs with the tile above or below it. Check every pair against the list before committing. If all pairs are legal, you score your word plus every pair, and the total is usually double what a perpendicular play would give you.

The rack fix. When your rack is badly balanced, a two-letter word is how you dump the problem without wasting a whole turn on an exchange. AA sheds two A tiles. HM and MM shed consonants. Playing a two-point word that leaves you a workable rack often beats a twenty-point word that leaves you stuck.

When you want to see every option from a specific set of letters rather than just the two-letter ones, put them into the Word Unscrambler. Results come back grouped by length, so the two-letter group is right there at the bottom, ready to check against whatever the board is offering.
