Quarrelled and bolted with trumpets (6,5)
I believe the answer is:
locked horns
'quarrelled' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'bolted with trumpets' is the wordplay.
'bolted' becomes 'locked' (synonyms).
'with' is a charade indicator (letters next to each other).
'trumpets' becomes 'horns' ('horn' can be a synonym of 'trumpet').
'locked'+'horns'='LOCKED HORNS'
'and' is the link.
Can you help me to learn more?
(Another definition for locked horns that I've seen is " Engaged in combat".)
