Like a certain poet composing in Corby (7)
I believe the answer is:
byronic
'like a certain poet' is the definition.
I can't tell whether this defines the answer.
'composing in corby' is the wordplay.
'composing' indicates anagramming the letters.
'in'+'corby'='incorby'
'incorby' is an anagram of 'BYRONIC'.
Can you help me to learn more?
(Other definitions for byronic that I've seen before include "Passionate and romantic, like English poet Lord" , "Poet's" , "Dark, mysterious, moody" , "Highly romantic" , "mad, bad, and dangerous to know?" .)
