Crossword Genius

Single traveller's nose (5)

Ross

I believe the answer is:

aroma

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

'single traveller's' is the wordplay.
'single' becomes 'a'.
'traveller' becomes 'roma' (as in Romani Travellers).
'a'+'roma'='AROMA'

(Other definitions for aroma that I've seen before include "Subtle quality" , "Fragrance of spices" , "Pervasive quality" , "Pervasive atmosphere" , "Distinctive smell" .)

I've seen this clue in The Guardian.
