Fastens around necks (4)
I believe the answer is:
ties
This might be a double definition.
'fastens' is the first definition.
(tying is a kind of fastening)
'necks' is the second definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe you can see an association between them that I can't see?
'around' is the link.
Can you help me to learn more?
(Other definitions for ties that I've seen before include "Drawn games" , "Items of neckwear" , "Links" , "obligations" , "allegiances" .)
