Porky's nose (5)
I believe the answer is:
snout
'porky's nose' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for snout that I've seen before include "Tobacco -- hooter" , "Animal's muzzle" , "Porker's hooter?" , "Schnozzle" , "Projecting nasal area of animal" .)
