Grab round the neck (6)
I believe the answer is:
collar
This clue could be a double definition.
'grab round' is the first definition.
'collar' can be an answer for 'grab' (thesaurus). I'm not sure about the 'round' bit.
'the neck' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for collar that I've seen before include "A cloth neck-band" , "Neck of shirt" , "Ruff" , "Appropriate - piece of neckwear" , "Nab the neck part?" .)
