If you are wondering whether or not a word is legal in the latest edition of the OSPD published by Merriam-Webster, there are a variety of tools available for you today.

Online Scrabble word checkers such as Hasbro's Scrabble Dictionary tool allow you to search if a word is an official Scrabble one. Both of these tools are for North American Scrabble games for English speakers in the United States, Canada, and Thailand.
