You’re about to plunk down your next play and rack up some serious points, but then you pause. Is your next Scrabble play actually legal? Will your opponent challenge you on whether it’s really a word?

Scrabble is all about finding the perfect playable word, but the keyword here is “playable.” And deciding whether a word is playable comes down to choosing a dictionary for your game. From the North American Scrabble Players Association Word List (NWL) to the Official Scrabble Player’s Dictionary (OSPD), each dictionary has advantages and disadvantages (plus some pretty specific rules). Here’s what you need to know to pick the perfect Scrabble dictionary next time you play.

Official Scrabble Player’s Dictionary (OSPD): Great for Casual Players

Not super serious about your Scrabble game? Just here to have some fun? The OSPD is the dictionary for you. This dictionary is perfect for players of any skill level or age, so it’s a great option if you’re just starting out.

  • The OSPD is awesome for using in schools because it defines each word and helps build vocab skills.

  • The basis for the OSPD is the Merriam Webster dictionary, so it’s a reliable resource.

  • The OSPD is also organized by category, so it’s super easy to search and browse.

North American Scrabble Players Association Word List (NWL): Ideal for US & Canadian Tournaments

If you’re a little more serious about your game, you might need a tournament-quality list like the NWL. This dictionary actually includes words you won’t find in the OSPD. Specifically, you’ll find stuff that could potentially be offensive and words that are trademarked.

  • The NWL is a really good dictionary if you plan to compete or play in a tournament.

  • If you want more word options, the NWL is your best bet.

  • You’ll find US and Canadian spellings in this dictionary, so it’s not for you if you’re planning to play in the UK or elsewhere.

Collins Scrabble Words (CSW): Perfect for International Play

Playing with people in different countries? You’ll need a Scrabble dictionary that works for everyone, and that’s where the CSW comes in. This dictionary includes words from the NWL and the OSPD, so it’s the perfect choice if you want to maximize your options.

  • The CSW includes both British and American English words.

  • Think of this Scrabble dictionary as a compromise for players from different countries.

  • This list includes definitions, so it’s good for building your vocabulary.

Tips to Help You Choose a Scrabble Dictionary

Don’t stress if you’re still not sure which Scrabble dictionary you should use. We’ve got some handy tips to help you decide:

  • Think about your location. If you’re in the US, choose the NWL or OSPD.

  • Consider other players. Do you have an opponent from another country? Pick an international list like the CSW.

  • Decide if you need definitions. Not every Scrabble dictionary defines the words. If you want to build your vocab or are playing with people who aren’t native English speakers, the CSW or OSPD are good choices.

  • Keep player level in mind. If you are a serious Scrabble player, a tournament dictionary like the CSW or NWL is good. If you’re just here to have fun, the OSPD is your go-to.
