Question: What is the difference between anyone and any one? I am trying to find a loop hole. In the statement "An adult MUST accompany any one under the age of 17." Does that mean that the adult can accompany for example 2 people?

Answer: 1A Use 'any one' of things and of person when 'one' has a numerical sense : Which pen do you want? - Any one will do.\n1B At all other times use 'anyone' of persons : Is anyone there?\n\n2A 'Anyone' is singular and normally takes a singular verb and is referred to by a singular pronoun : Has anyone a book he can lend me?\n2B When anyone has the force of 'all', without exception, the singular would sound out of keeping and the plural is normally used : Anyone can enter for the Art Contest, can't they?
