Peculiar person (10)
I believe the answer is:
individual
I believe this is a double definition.
'peculiar' is the first definition.
(I've seen this before)
'person' is the second definition.
('individual' can be a synonym of 'person')
(Other definitions for individual that I've seen before include "single person" , "Singular; distinctive" , "One person" , "party" , "Peculiar" .)
