Well-qualified (4)
I believe the answer is:
able
'well-qualified' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for able that I've seen before include "Qualified - expert" , "... was I ere I saw Elba (palindrome)" , "Bale out, being competent" , "Practised" , "- -bodied; - seaman" .)
