Bowler perhaps receiving a mouthful in home ground (7)
I believe the answer is:
habitat
'home ground' is the definition.
(I've seen this before)
'bowler perhaps receiving a mouthful' is the wordplay.
'bowler perhaps' becomes 'hat' (bowler is a kind of hat).
'receiving' indicates putting letters inside.
'mouthful' becomes 'bit' (bit is a kind of mouthful).
'a'+'bit'='abit'
'hat' enclosing 'abit' is 'HABITAT'.
'in' is the link.
(Other definitions for habitat that I've seen before include "One's normal environment" , "Domain" , "Environment in which an organism normally lives" , "Usual abode" , "place haunted" .)
