Hogwarts attendee with zero wit coming over (5)
I believe the answer is:
draco
'hogwarts attendee' is the definition.
I can't tell whether this definition defines the answer.
'with zero wit coming over' is the wordplay.
'with' is a charade indicator (letters next to each other).
'zero' becomes 'O' (O resembles 0).
'wit' becomes 'card' (synonyms).
'coming over' says the letters should be written backwards.
'o' next to 'card' is 'ocard'.
'ocard' written backwards gives 'DRACO'.
Can you help me to learn more?
(Other definitions for draco that I've seen before include "Athenian lawmaker" , "Ruthless lawmaker" , "seen among the stars" , "Constellation, the Dragon" , "Athenian statesman" .)
