Adding word is a type of wordplay in which a new word is created by adding one or more letters to an existing word. This can be done in a variety of ways, such as adding a prefix or suffix, or rearranging the letters of the original word. Adding word is often used in crossword puzzles, where the clue for the answer is usually a hint at the new word that needs to be created. The answer to the clue is usually the new word that has been created by adding one or more letters to an existing word.
