Quarrel about stopping change (11)
I believe the answer is:
altercation
'quarrel' is the definition.
(altercation is a kind of quarrel)
'about stopping change' is the wordplay.
'about' becomes 'c' (circa).
'stopping' is an insertion indicator (inserted letters stop or plug a gap).
'change' becomes 'alteration' (alteration is a kind of change).
'c' inserted within 'alteration' is 'ALTERCATION'.
(Other definitions for altercation that I've seen before include "Noisy argument" , "heated argument" , "Spat" , "Rattle a coin (anag) - row" , "heated dispute" .)
