The odd unknown (7)

Ross

I believe the answer is:

strange

I believe this clue is a double definition.

'the odd' is the first definition.
(I've seen this in another clue)

'unknown' is the second definition.
(associated in meaning)

(Other definitions for strange that I've seen before include "Peculiar; Morse's boss" , "Extraordinary" , "Out of the ordinary" , "Queer" , "Foreign" .)

I've seen this clue in the Evening Standard.
