One’s to squeeze the ring into the loop (5)
I believe the answer is:
noose
'the loop' is the definition.
(synonyms)
'one's to squeeze the ring' is the wordplay.
I cannot quite understand how this works, but
'one's' could be 'os' (I've seen this in other clues) and 'os' is present in the answer.
'ring' could be 'o' (letter resembling a ring) and 'o' is present in the answer.
The remaining letters 'ne' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'into' is the link.
Can you help me to learn more?
(Other definitions for noose that I've seen before include "marriage, for a laugh" , "Ring of rope" , "Hangman's equipment" , "Loop in a lariat" , "Hanging material" .)
