Team having a row scoffed audibly (5)
I believe the answer is:
eight
'team having a row' is the definition.
(rowing team of eight rowers)
'scoffed audibly' is the wordplay.
'scoffed' becomes 'ate' ('to scoff' is to eat).
'audibly' shows a homophone (sound like).
'ate' sounds like 'EIGHT'.
(Other definitions for eight that I've seen before include "1,001 - 993" , "Half a quarter" , "Number etched by a skater?" , "One over it and you were drunk, it was said" , "2 cubed" .)
