Turns up and listens (7)
I believe the answer is:
attends
'listens' is the definition.
(attending is a kind of listening)
'turns up' is the wordplay.
I cannot really see how this works, but
'turns' could be 'ends' (ending is a kind of turning) and 'ends' is found in the answer.
The remaining letters 'att' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for attends that I've seen before include "Heeds" , "to listen carefully" , "Waits on or is present" , "Listens" , "Pays attention" .)
