My sweet nothings (5)
I believe the answer is:
ducks
'nothings' is the definition.
The definition and answer can be both quantities as well as being plural nouns.
Maybe there's an association between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for ducks that I've seen before include "Eg, mallards" , "Birds with webbed feet" , "Swimming birds with scores of nothing?" , "More than one aquatic bird" , "My pet" .)
