Still divisible by two (4)

Ross

I believe the answer is:

even

This clue is a double definition.

'still' is the first definition.
(I know that still can be written as even)

'divisible by two' is the second definition.
(I've seen this before)

(Other definitions for even that I've seen before include "Level, calm" , "Plumb" , "Still - quits" , "Smooth, uniform in quality" , "Regular - smooth" .)

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