Physician grasping lesson on European complaint (5)
I believe the answer is:
gripe
'complaint' is the definition.
(an objection or source of annoyance)
'physician grasping lesson on european' is the wordplay.
I cannot really understand how this works, but
'grasping' could be 'grip' (grip is a kind of grasping) and 'grip' is located in the answer.
'european' could be 'e' (abbreviation e.g. EU) and 'e' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gripe that I've seen before include "Keep on complaining" , "Grievance" , "Trivial complaint" , "Complain; colic (water)" , "beef" .)
