Keep wife in cricket side (3)
I believe the answer is:
own
'keep' is the definition.
(I've seen this before)
'wife in cricket side' is the wordplay.
'wife' becomes 'w'.
'in' is an insertion indicator.
'cricket side' becomes 'on'.
'w' placed inside 'on' is 'OWN'.
(Other definitions for own that I've seen before include "Acknowledge" , "Posses" , "Keep" , "Control" , "Private" .)
