Entertain a bird at the West End (6)
I believe the answer is:
divert
'entertain' is the definition.
(diverting is a kind of entertaining)
'a bird at the west end' is the wordplay.
I cannot really see how this works, but
'bird' could be 'diver' (diver is a kind of bird) and 'diver' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' 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 divert that I've seen before include "Entertain; reallocate" , "Amuse or re-route" , "Capture attention of" , "offer entertainment" , "Amuse, or turn from normal course" .)
