Abscond with lover from Basel Opera (5)
I believe the answer is:
elope
'abscond' is the definition.
(I've seen this before)
'from basel opera' is the wordplay.
'from' says the answer is hidden in the clue.
'ELOPE' is hidden within 'basel opera'.
'with lover' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for elope that I've seen before include "Run away secretly to marry" , "do a moonlight flit" , "Run away together" , "Bolt" , "leave with lover" .)
