Chauvinist, perhaps, is able to welcome male bores (7)
I believe the answer is:
caveman
'chauvinist' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'is able to welcome male bores' is the wordplay.
'is able to' becomes 'can' (if you can do something you are able to do it).
'welcome' becomes 'ave' ('welcome' or 'farewell' - from Latin).
'male' becomes 'm' (common abbreviation).
'bores' means one lot of letters goes inside another (bore can mean to drill into).
'ave'+'m'='avem'
'can' enclosing 'avem' is 'CAVEMAN'.
'perhaps' is the link.
Can you help me to learn more?
(Other definitions for caveman that I've seen before include "Prehistoric chap" , "Prehistoric male" , "Prehistoric human" , "Troglodyte" , "Prehistoric person" .)
