Cleric not dancing? Drug needed first is E! (10)
I believe the answer is:
electronic
'is e' is the definition.
I can't tell whether this defines the answer.
'cleric not dancing? drug needed' is the wordplay.
'dancing?' indicates an anagram.
'drug' becomes 'e' (E is another name for ecstasy).
'needed' means one lot of letters goes inside another.
'cleric'+'not'='clericnot'
'clericnot' is an anagram of 'elctronic'.
'elctronic' going around 'e' is 'ELECTRONIC'.
'first' acts as a link.
Can you help me to learn more?
(Other definitions for electronic that I've seen before include "of some modern technology" , "Like a computer" , "using a computer?" , "Like a PC" , "Like microcircuitry" .)
