Why two-letter words are strategically important

Short words are not filler. They let you play beside existing words, connect isolated sections of the board, unload difficult tiles, and reach premium squares. A two-letter word can create several cross words in a single turn.

Competitive word games accept additional two-letter entries that may be uncommon in everyday English. Because official lists differ, verify the exact set in the dictionary used by your game.

How to memorize them

Learn words in groups of five, use flash cards in both directions, and practice adding each word beside an existing word. Retrieval in a board context is more valuable than simply recognizing a printed list.
