Showed contempt during row (4)
I believe the answer is:
spat
'showed contempt' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for spat that I've seen before include "A small tiff or quarrel" , "Legging covering instep and ankles" , "Taps in minor quarrel" , "Contretemps" , "Minor conflict" .)
