Nick Drake gutted about wearing pants (9)
I believe the answer is:
trousered
'gutted about wearing pants' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives occasionally define each other.
'nick drake' is the wordplay.
'nick' becomes 'trouser' (both can mean to steal).
'drake' becomes 'ed' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'trouser'+'ed'='TROUSERED'
Can you help me to learn more?
(Other definitions for trousered that I've seen before include "Took for oneself" , "Decently attired" , "pocketed cash?" , "Drunk -- stole" , "in jeans?" .)
