Two-Letter Words: The Full List

Last updated: October 1, 2026

The open ENABLE word list that Letterpile uses has 96 two-letter words. They are listed below by first letter, each with a short note on what it means. Different games accept different two-letter words, so treat this as the list for this site, not a rule for every game. Words come from the open ENABLE word list. Different games use different dictionaries, so always check the rules of your game.

Why two-letter words matter

In crossword-style tile games, long words get the attention, but two-letter words do much of the work. They let you place a word alongside another one, forming several short words at once, and they let a single high-value tile touch a bonus square without needing a long word around it. Because there are only 96 of them here, learning them is one of the quickest ways to find more places to play.

Patterns in the list

A starts the most two-letter words (16).
49 of the 96 start with a vowel, which is why vowels are easy to place next to other words.
5 have no A, E, I, O or U: BY, HM, MM, MY and SH.
No two-letter word in this list starts with C, Q, V, Z. The letters C, Q, V, Z do not appear in any of them.
Using commonly used tile values, the highest-scoring two-letter words are AX (9), EX (9), JO (9), OX (9), XI (9), XU (9).

Words this list does not have

Returning visitors may notice that some familiar short words are gone. Until recently Letterpile used a different, larger list with 124 two-letter words; it was replaced by ENABLE, which has a clear public-domain release. Some games accept QI and ZA, and casual speech uses OK and EW, but none of those four is in the list this site uses. If your game accepts them, use them there; they just won't appear in Letterpile's results.

That difference is normal. Word games each choose a dictionary, and those dictionaries disagree most about short, informal and borrowed words. Word Lists Explained covers why.

How to learn them

Start with the ones you already know. Most of the list is everyday English: pronouns, prepositions and interjections. Cross those off first.
Learn the unusual ones in groups. Musical notes (DO, RE, MI, FA, LA and TI), letter names (AR, EF, EL, EM, EN and ES) and Greek letters (MU, NU, XI and PI) are easier to remember together.
Practice hooks. For each letter, ask which two-letter words it can start or end. The hooks guide explains why that helps.
Check with a tool. Typing two letters into the Word Unscrambler with “use every letter” on tells you instantly whether they form a word in this list.
