Flower sheltered by city in wind (8)
I believe the answer is:
easterly
'wind' is the definition.
(easterly is a kind of wind)
'flower sheltered by city' is the wordplay.
'flower' becomes 'aster' (aster is a kind of flower**).
'sheltered by' means one lot of letters goes inside another.
'city' becomes 'ely' (I've seen this before).
'aster' placed into 'ely' is 'EASTERLY'.
'in' is the link.
(Other definitions for easterly that I've seen before include "bitter blow for the UK" , "Year's let (anag) - direction of 15" , "A wind blowing towards the west" , "The sort of wind that brings cold air to this country" , "Wind to westward" .)
