Not in the mood to get the duet transcribed (8)
I believe the answer is:
outmoded
'transcribed' is the definition.
Both the answer and definition are adjectives. Maybe there's a link between them I don't understand?
'not in the mood to get the duet' is the wordplay.
'not in' becomes 'out' ('out' is the opposite to 'in').
'the mood' becomes 'mode' (synonyms).
'to get the duet' becomes 'd' (I can't explain this - if you can you should believe this answer much more).
'out'+'mode'+'d'='OUTMODED'
Can you help me to learn more?
(Other definitions for outmoded that I've seen before include "No longer fashionable" , "Dated" , "Old-fashioned" , "No longer in fashion" .)
