Husband overwhelmed by better bloke (4)
I believe the answer is:
chap
'bloke' is the definition.
(thesaurus)
'husband overwhelmed by better' is the wordplay.
'husband' becomes 'h'.
'overwhelmed by' means one lot of letters goes inside another (I've seen this in other clues).
'better' becomes 'cap' (I've seen this before).
'h' inserted into 'cap' is 'CHAP'.
(Other definitions for chap that I've seen before include "Sore; cheek; man" , "Fellow < makes > crack" , "we prefer not to have on hand" , "Cracked patch (of skin) - gentleman" , "Man, boy, fellow" .)
