Talented at making headwear competent (7)
I believe the answer is:
capable
'talented' is the definition.
(thesaurus)
'headwear competent' is the wordplay.
'headwear' becomes 'cap' (cap is a type of hat).
'competent' becomes 'able' (similar in meaning).
'cap'+'able'='CAPABLE'
'at making' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for capable that I've seen before include "Of a person, competent" , "accomplished" , "Adept" , "Efficient" , "Able, competent" .)
