One runs around wicket keeper (5)
I believe the answer is:
owner
'keeper' is the definition.
(I've seen this before)
'one runs around wicket' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'around' means one lot of letters goes inside another.
'wicket' becomes 'w'.
'one'+'r'='oner'
'oner' enclosing 'w' is 'OWNER'.
(Other definitions for owner that I've seen before include "Person with legal title to something" , "Person having property" , "Holder, proprietor" , "landlord" , "Title holder?" .)
