Strap around thigh compressing artery walls (6)
I believe the answer is:
garter
'strap around thigh' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'compressing artery walls' is the wordplay.
'GARTER' is hidden within the letters.
However, I'm uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for garter that I've seen before include "Band holding up sock" , "It holds a stocking up" , "Stocking supporter" , "Band around the leg or arm" , "Band worn on leg" .)
