Fasten around the neck (3)
I believe the answer is:
tie
This might be a double definition.
'fasten' is the first definition.
(I know that fasten is a more specific form of attach)
'the neck' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'around' acts as a link.
Can you help me to learn more?
(Other definitions for tie that I've seen before include "Draw; link" , "Draw - knot" , "Level result" , "Equal score" , "line above notes" .)
