Give a girl a ring - a running noose! (5)
I believe the answer is:
lasso
'a running noose' is the definition.
'lasso' can be an answer for 'noose' (I've seen this before). I'm unsure of the 'a running' bit.
'give a girl a ring' is the wordplay.
'give' says to put letters next to each other.
'a girl' becomes 'lass' (lass can informally mean a girl).
'a ring' becomes 'o' (O is the shape of a ring).
'lass' put next to 'o' is 'LASSO'.
Can you help me to learn more?
(Other definitions for lasso that I've seen before include "One may be caught by this" , "Ling-nosed rope" , "Belgian composer" , "Rope with 20" , "snare" .)
