Give in to temptation before striking quarrel (4,3)
I believe the answer is:
fall out
'give' is the definition.
(I know that give is a more specific form of the action fall out)
'before striking quarrel' is the wordplay.
'before' is a charade indicator (letters next to each other).
'striking' becomes 'out' (striking out is a common phrase).
'quarrel' becomes 'fall' (I've seen this before).
'out' put after 'fall' is 'FALL-OUT'.
'in to temptation' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for fall out that I've seen before include "disagree" , "Happen" , "Radioactive pollution" , "Quarrel - leave the ranks" .)
