Try to detect an odour (5)

Ross

I believe the answer is:

sniff

(Other definitions for sniff that I've seen before include "Smell at" , "Snuffle" , "Inhale (glue); slight suspicion" , "What tracker dogs do" , "Slight suspicion (perceived though the nose?)" .)

I've seen this clue in the Sydney Morning Herald.
