Lasso loop squirrelled away in bouquet (5)
I believe the answer is:
noose
'lasso loop' is the definition.
(I've seen this in another clue)
'squirrelled away in bouquet' is the wordplay.
'squirrelled away' becomes 'o' (I am not sure about this - if you are sure you should believe this answer much more).
'in' indicates putting letters inside.
'bouquet' becomes 'nose' (both can mean a smell).
'o' inserted within 'nose' is 'NOOSE'.
Can you help me to learn more?
(Other definitions for noose that I've seen before include "head could go in it" , "Loop of rope with a slipknot" , "Loop - snare" , "Loop with sliding knot in a rope" , "Loop of cord" .)
