Sailor found among vegetarians (3)
I believe the answer is:
tar
'sailor' is the definition.
(tar is a kind of sailor)
'among vegetarians' is the wordplay.
'among' indicates the answer is hidden within the clue.
'TAR' is hidden in the letters of 'vegetarians'.
'found' acts as a link.
(Other definitions for tar that I've seen before include "Black liquid from coal" , "Road surfacing or old sailor" , "Dark viscous stuff" , "Kind of rat for sailor" , "A sailor; a preservative" .)
