Blow over, causing delight (5)
I believe the answer is:
gusto
'delight' is the definition.
(thesaurus)
'blow over' is the wordplay.
'blow' becomes 'gust' ('gust' can be a synonym of 'blow'**).
'over' becomes 'o' (cricket abbreviation).
'gust'+'o'='GUSTO'
'causing' is the link.
(Other definitions for gusto that I've seen before include "Relish - zest" , "Verve, zest" , "(Corporate) emblem" , "exhilaration" , "Relish; vigour" .)
