Might this describe Boatman: finished with work? (8)
I believe the answer is:
fiendish
'might' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives sometimes define each other.
'this describe boatman finished with work?' is the wordplay.
'finished' can be anagrammed to 'FIENDISH'.
However, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for fiendish that I've seen before include "Extremely cruel" , "Diabolical" , "like some Sudokus" , "very hard" , "Very difficult" .)
