The term 'handwritten name' can be broken down into two crossword solutions: SIGNATURE and AUTOGRAPH. A SIGNATURE is a person's name written in their own handwriting, typically used to signify agreement or authorization on a document. An AUTOGRAPH is a person's SIGNATURE, usually accompanied by a brief message, that is written as a form of a personal memento or souvenir. Both signatures and autographs are often collected by fans of celebrities, athletes, and other public figures.
