Being soft on Enid, perhaps, was moody (5)
I believe the answer is:
pined
'moody' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can occasionally mean the same thing.
'being soft on enid perhaps' is the wordplay.
'being soft' becomes 'p' (musical abbreviation for 'piano').
'on' says to put letters next to each other.
'perhaps' indicates anagramming the letters.
'enid' anagrammed gives 'ined'.
'p'+'ined'='PINED'
'was' acts as a link.
Can you help me to learn more?
(Other definitions for pined that I've seen before include "Starved" , "Languished, yearned" , "Became ill with longing" , "Longed; wasted (away)" .)
