Risking swallowing large sweet (7)
I believe the answer is:
darling
'sweet' is the definition.
(both are terms of endearment)
'risking swallowing large' is the wordplay.
'risking' becomes 'daring' (daring can mean to take a risk).
'swallowing' indicates putting letters inside.
'large' becomes 'L' (eg in clothes sizes).
'daring' enclosing 'l' is 'DARLING'.
(Other definitions for darling that I've seen before include "Adorable - honeybun" , "Grace -, nineteenth century wreck heroine of lighthouse" , "Favourite" , "Term of affection" , "Pet" .)
