Scent bait entering country (9)
I believe the answer is:
fragrance
'scent' is the definition.
(fragrance is a kind of scent)
'bait entering country' is the wordplay.
'bait' becomes 'rag' ('rag' can be a synonym of 'bait').
'entering' means one lot of letters goes inside another.
'country' becomes 'france' (France is an example**).
'rag' placed inside 'france' is 'FRAGRANCE'.
(Other definitions for fragrance that I've seen before include "Sweet smell" , "Pleasant aroma as of flower" , "Pleasant scent" , "Sweetness of smell" , "Cologne, perhaps" .)
