Just went ahead and nuzzled? (5)
I believe the answer is:
nosed
'nuzzled?' is the definition.
('nose' can be a synonym of 'nuzzle')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nosed that I've seen before include "edged out" , "Pried" , "proceeded cautiously" , "Scented" , "Checked wine's aroma" .)
