Jersey is a little larger than this garment (8)
I believe the answer is:
guernsey
This could be a double definition.
'jersey' is the first definition.
The answer and definition can be both animals as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'little larger than this garment' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'is a' is the link.
Can you help me to learn more?
(Other definitions for guernsey that I've seen before include "Source of milk" , "Lyric poem" , "off the Needles?" , "Lower" , "Channel isle" .)
