No particular one' is a phrase that is used to describe something that does not have a specific choice or selection. It is often used when referring to a group of people, objects, or ideas that are not singled out from the rest. For example, if someone were asked which person in a group they liked the most, they might respond with 'no particular one'. This phrase can also be used to indicate that there is no preference or priority given to ANY one thing over another.
