Troubadour and tenor involved in Merlin's destruction (8)
I believe the answer is:
minstrel
'troubadour' is the definition.
('minstrel' can be a synonym of 'troubadour')
'tenor involved in merlin's destruction' is the wordplay.
I cannot really understand how this works, but
'tenor' could be 't' and 't' is located in the answer.
'in' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for minstrel that I've seen before include "Old song 'The ... boy to the wars has gone'" , "Balladeer" , "Old travelling musician - a boy in Irish song" , "Jongleur" , "Nanki-Poo, for instance" .)
