Group of rowers fed, we can hear (5)
I believe the answer is:
eight
'group of rowers' is the definition.
'eight' can be an answer for 'rowers' (eight can mean a crew of eight rowers). I am not certain of the 'group of' bit.
'fed we can hear' is the wordplay.
'fed' becomes 'ate' ('eat' can be a synonym of 'feed').
'we can hear' shows a homophone (sound like).
'ate' sounds like 'EIGHT'.
Can you help me to learn more?
(Other definitions for eight that I've seen before include "Four twos" , "Pints in gallon" , "Number (with pieces?)" , "Number that figures in ice-skating?" , "Number for rowers" .)
