Curse lamb and sheep, straying together (9)
I believe the answer is:
blaspheme
'straying together' is the definition.
I can't judge whether this defines the answer.
'curse lamb and sheep' is the wordplay.
'curse' indicates anagramming the letters (I've seen 'cursed' mean this (a damaged or cursed form of the letters)).
'and' is a charade indicator (letters next to each other).
'lamb' after 'sheep' is 'sheeplamb'.
'sheeplamb' anagrammed gives 'BLASPHEME'.
Can you help me to learn more?
(Other definitions for blaspheme that I've seen before include "Swear" , "Say irreverent things about God" , "Talk irreverently about God and sacred things" , "Speak profanely" , "Speak irreverently about God" .)
