The Ultimate Guide to Memorizing 2-Letter Scrabble Words

Two-letter words are the secret weapon of every Scrabble champion. They look trivial — just two tiles on a board — but they unlock positional value that long words cannot reach. A well-placed 2-letter word lets you parallel-play alongside an existing word, score both words' tile values twice, and block opponents from extending plays. The 107 valid 2-letter words in the NWL2023 (North American) Scrabble dictionary are the foundation of competitive play, and memorizing them is the single highest-ROI vocabulary investment you can make. This guide walks through why 2-letter words matter, gives you the complete list grouped by memorization strategy, and shows you exactly how to use WordIzy to drill them into long-term memory.

Why 2-Letter Words Win Games

Three reasons 2-letter words punch far above their point value. First, parallel play: if your opponent plays SLATE horizontally, you can play AA, AB, or AD vertically through the A tile, scoring your small word AND the cross-points from the S, L, T, and E you parallel. Second, board access: 2-letter words let you reach premium squares that long words cannot geometrically reach, often doubling or tripling a high-value tile like Q or Z. Third, rack management: when your rack is cluttered with vowels or consonants, a 2-letter word lets you dump unwanted tiles (AA, OE, AI) while keeping position for the next turn. The pros call these "vowel dumps" — they're essential for keeping your rack balanced.

The Complete NWL2023 Two-Letter Word List (107 Words)

Here is the full list grouped by first letter. Memorize the rows as visual chunks — most players learn them by visualizing each row as a single mental image rather than memorizing letter-by-letter.

• A: AA, AB, AD, AE, AG, AH, AI, AL, AM, AN, AR, AS, AT, AW, AX, AY
• B: BA, BI, BO, BY

Memorization Strategy 1: Group by Vowel Pairings

The most efficient memorization method is to drill the vowel-led 2-letter words first, because they're the highest-frequency plays and the easiest to recall. AA, AE, AI, AO, EA, EE, EI, EO, IA, IE, II, IO, OA, OE, OI, OO, OU, UA, UE, UI, UO — each of these is a valid word in NWL2023. Treat the vowels as "anchor letters" and memorize which consonants they pair with. For example, "E pairs with every vowel plus D, E, F, H, L, M, N, R, S, T, W, X, Y" — that's 19 E-led 2-letter words, the densest consonant cluster.

Memorization Strategy 2: The Q, X, Z, J Quartet

The 4 highest-value letters each have a small but crucial set of 2-letter companions. Q pairs only with I (QI). X pairs with I and U (XI, XU). Z pairs with A and O (ZA, ZO). J pairs with A and O (JA, JO). Memorize this quartet first because these are the words you'll play when you draw a high-value tile and need to dump it for points. QI is especially valuable — it's the only way to play a Q without a U, and you'll encounter this rack situation dozens of times per tournament.

Memorization Strategy 3: Spaced-Repetition Flashcards with the Save Vault

The fastest way to memorize the 107 words permanently is spaced repetition. Use WordIzy's built-in Save Vault feature to bookmark every 2-letter word from the /words-starts-with-a through /words-starts-with-z pages, then click "Copy All Lines" and paste the list into Anki or Quizlet. Review the deck for 10 minutes a day — within two weeks you'll have all 107 words in long-term memory, and within a month they'll be reflexive. The vault keeps each word's Scrabble score visible so you can drill the high-value entries (QI, XU, ZA, JO, AX, OX, EX) more aggressively.

Strategic Use in Real Games

Once you have the 2-letter words memorized, three strategic plays unlock. First, parallel hooks: lay a 2-letter word alongside an existing word to score the cross-tiles twice — placing AA next to BAKED scores both A's plus the cross-value of B, K, E, D. Second, defensive blocks: a 2-letter word like QI or XU placed near a triple-word lane locks that lane behind an unhookeable shape, blocking opponents from extending plays. Third, rack-balancing dumps: when your rack is vowel-heavy (AEIOUU), dump the extra U through UT, UM, UN, or UP to keep your rack bingo-ready. The 2-letter words are not glamorous, but the player who knows them all out-scores the player who doesn't by 30 to 50 points per game.

Closing

Memorizing 107 two-letter words is the highest-ROI vocabulary investment in Scrabble. Two weeks of focused spaced-repetition drilling will permanently raise your scoring baseline. Bookmark the /unscramble-2-letter-words page, save every entry to your vault, and start drilling today. The next time you face a Q without a U, a cluttered vowel rack, or a parallel-play opportunity, you'll have the answer locked in muscle memory.
