Odd, peculiar (7)
I believe the answer is:
strange
I believe this is a double definition.
'odd' is the first definition.
(I know that odd can be written as strange)
'peculiar' is the second definition.

(Other definitions for strange that I've seen before include "Extraordinary" , "- - Fruit (song)" , "Odd - rum" , "Odd kind of garnets" , "Odd, peculiar" .)
