When you're playing Scrabble and someone lays down a suspicious word, you need to quickly verify if it's actually valid. This usually means checking against the official Scrabble dictionary, but since that's not always handy, online word checkers or mobile apps can do the job. They cross-reference your word with the allowed list, confirming if it's legal for play—saving arguments and keeping the game moving.
