A little strange (3)
I believe the answer is:
odd
'a little strange' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for odd that I've seen before include "Bizarre - occasional" , "Number not divisible by two" , "like twenty two [FIFTEEN]? Yes and no!" , "Queer" , "Peculiar or unpaired" .)
