Person who doesn't mingle (5)

Ross

I believe the answer is:

loner

(Other definitions for loner that I've seen before include "Enrol (anag)" , "Solitary individual, prefers own company" , "Person who prefers his own company" , "One shunning society" , "One not desiring companionship" .)

I've seen this clue in the Newsday.
