A non-specific individual is someone who does not have a specific identity or role. This term can be used to refer to any person, regardless of their background, profession, or other characteristics. It is often used in legal contexts to refer to an unnamed person or group of people. In the context of a crossword puzzle, the term 'ANYONE' is a fitting solution for the clue 'non-specific individual' as it implies that ANYONE could fit the description.
