Word check
Is It a Word?
24 arguments people actually have, each answered twice: whether the spelling is in the dictionary this site searches, and separately whether careful writing would use it. Those two questions have different answers more often than you would think.
15 of the 24 are in the list; 9 are not.
Any other word
The checker takes any word and gives the same honest verdict: in the list or not, with the tile score and a one-line definition where one exists. It never pads an answer to keep you clicking.
