They may be pushed by street vendors to stop fights (7)
I believe the answer is:
barrows
'they may be pushed by street vendors' is the definition.
The definition suggests an adverb but the answer is not.
'stop fights' is the wordplay.
'stop' becomes 'bar' (I've seen this before).
'fights' becomes 'rows'.
'bar'+'rows'='BARROWS'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for barrows that I've seen before include "They're found in gardens'" , "Places formerly used for burying" , "Handcarts" , "decomposing mounds" .)
