Words in word games
If you are playing a word game, knowing whether a word is valid is essential. Delta appears in our 370,000-word English dictionary, which includes most words accepted in Scrabble and Words With Friends. However, always check the official word list for the specific game you are playing, as different games use different dictionaries.
Scrabble
In Scrabble, the valid word lists are the Official Tournament and Club Word List (OTCWL/NWL) for North America and the Collins Scrabble Words (CSW) for international play. Our dictionary covers most words in both lists, but some proper nouns, abbreviations, and offensive terms may differ.
Wordle
Wordle uses its own curated word list that is smaller than the full Scrabble dictionary. If Delta appears here, it may or may not be a valid Wordle answer — but it is a real English word regardless.
