I’m a derogatory comment as intended by a prankster? (6)
I believe the answer is:
impish
'i'm a derogatory comment' is the definition.
I can't tell whether this definition defines the answer.
'intended by a prankster?' is the wordplay.
'intended' becomes 'ish' (I am not sure about this - if you are sure you should believe this answer much more).
'by' means one lot of letters go next to another.
'a prankster?' becomes 'imp' (I've seen this in another clue).
'ish' put after 'imp' is 'IMPISH'.
'as' is the link.
Can you help me to learn more?
(Other definitions for impish that I've seen before include "Naughty" , "troublesome" , "Playful" , "Mischievous like small devil" , "Mischievous like small fairy" .)
