Nose traveller follows back from India (5)
I believe the answer is:
aroma
'nose' is the definition.
(I've seen this before)
'traveller follows back from india' is the wordplay.
'traveller' becomes 'roma' (as in Romani Travellers).
'follows' means one lot of letters go next to another.
'back from' suggests the final letters (the letter at the back of the word).
The final letter of 'india' is 'a'.
'roma' put after 'a' is 'AROMA'.
(Other definitions for aroma that I've seen before include "Agreeable odour" , "Odour, mostly pleasing" , "Distinctive scent" , "Scent - fragrance" , "particular charm" .)
