Naive and stupid, snorting cocaine earlier (2,7)
I believe the answer is:
in advance
'earlier' is the definition.
Both the answer and definition are adverbs. Perhaps they are linked in a way I don't understand?
'naive and stupid snorting cocaine' is the wordplay.
'stupid' indicates an anagram (in a stupid order).
'snorting' means one lot of letters goes inside another (snort can mean to ingest through the nose).
'cocaine' becomes 'C' (drugs abbreviation).
'naive'+'and'='naiveand'
'naiveand' with letters rearranged gives 'inadvane'.
'inadvane' going around 'c' is 'IN ADVANCE'.
Can you help me to learn more?
(Other definitions for in advance that I've seen before include "Ahead in place or time" , "Beforehand - can invade accordingly (2.7)" , "early" , "Before the event" .)
