Nectar may produce a state of ecstasy (6)
I believe the answer is:
trance
'a state of ecstasy' is the definition.
'trance' can be an answer for 'ecstasy' (I've seen this before). I'm not certain of the 'a state of' bit.
'nectar may produce' is the wordplay.
'may produce' indicates an anagram (I've seen 'might produce' mean this (I've seen this in other clues)).
'nectar' with letters rearranged gives 'TRANCE'.
Can you help me to learn more?
(Other definitions for trance that I've seen before include "Reverie" , "Canter into state of hypnosis" , "Sleep-like, half-conscious state" , "Canter into one of these at a seance" , "Canter about a daydream" .)
