Is There a Difference?
Are 'anyone' and 'any one' both correct words in English? Do they have the same meaning? Can we use them interchangeably? Let's find out.
Anyone vs. Any One
'Anyone' is an indefinite pronoun referring to an unspecified person. It means any person at all no matter who.
'Any one' (with space between the words 'any' and 'one') is not an indefinite pronoun. It is a noun phrase comprised of two separate words 'any' and 'one'. It refers to one of the two or more things or people.
