My opponent played the word "yald". I questioned its validity. On your web site it is listed as valid and then gives dictionary.com and meriam-webster dictionary to check. When you check those sources they both say there is no such word. I believe you mean the word "yauld" which is a valid word. My opponent says if the game lets you play it, it is valid, even though there is no such word. Obviously, you have made a mistake. Please correct this as my opponent refuses to acknowledge that "yald" is not a word.
