Felt professional (11)
I believe the answer is:
experienced
I believe this is a double definition.
'felt' is the first definition.
('experience' can be a synonym of 'feel')
'professional' is the second definition.
(thesaurus)
(Other definitions for experienced that I've seen before include "Benefitting from previous actions" , "Practised, well-versed" , "Practised and knowledgeable" , "went through" , "No novice" .)
