Rush of air from wide behind (4)
I believe the answer is:
waft
'rush of air' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Maybe you can see a link between them that I don't see?
'wide behind' is the wordplay.
'wide' becomes 'w' (abbreviation e.g. in cricket).
'behind' becomes 'aft' (aft means towards or at the end of a ship).
'w'+'aft'='WAFT'
'from' is the link.
Can you help me to learn more?
(Other definitions for waft that I've seen before include "Be carried on the breeze" , "flag" , "Drift (like a faint smell)" , "scent" , "Gently move" .)
