Crossword Genius

One is so unusual (3)

Ross

I believe the answer is:

odd

I believe this is a double definition.

'one is' is the first definition.
(I've seen this before)

'unusual' is the second definition.
(similar in meaning)

'so' acts as a link.

(Other definitions for odd that I've seen before include "It's certainly not even" , "Peculiar or eccentric" , "Left over" , "like half the numbers?" , "Extraordinary" .)

I've seen this clue in The Globe and Mail.
