Spy's assumption (5)

Ross

I believe the answer is:

alias

'spy's assumption' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for alias that I've seen before include "False identity" , "Pseudonym" , "another name" , "Assumed identity" , "False or assumed name" .)

I've seen this clue in The New York Times.
