Ducks outside range freely, finding something smelling nice (7)
I believe the answer is:
oregano
'something smelling nice' is the definition.
'ducks outside range freely' is the wordplay.
'ducks' becomes 'oo' (I've seen this in other clues).
'outside' means one lot of letters goes inside another.
'freely' is an anagram indicator.
'range' with letters rearranged gives 'regan'.
'oo' going around 'regan' is 'OREGANO'.
'finding' is the link.
(Other definitions for oregano that I've seen before include "Wild marjoram" , "Herb - a no-goer (anag)" , "food flavouring" , "part of Mediterranean diet?" , "Pungent seasoning leaves" .)
