They like eating bread, nothing special (5)
I believe the answer is:
ducks
'they like eating bread' is the definition.
The definition suggests an adverb but the answer is not.
'nothing special' is the wordplay.
'nothing' becomes 'duck' (duck means zero in cricket).
'special' becomes 'S' (common abbreviation as in Special Air Service).
'duck'+'s'='DUCKS'
Can you help me to learn more?
(Other definitions for ducks that I've seen before include "Eg, mallards" , "Birds - term of endearment (informal)" , "Teal, wigeon etc" , "Lowers head suddenly" , "Common water birds" .)
