Stress seen in sheep as I'm around! (9)
I believe the answer is:
emphasise
'stress' is the definition.
(I know that stress can be written as emphasise)
'sheep as i'm around' is the wordplay.
'around' indicates an anagram.
'sheep'+'as'+'im'='sheepasim'
'sheepasim' with letters rearranged gives 'EMPHASISE'.
'seen in' is the link.
(Other definitions for emphasise that I've seen before include "'Stress, accentuate (9)'" , "Place stress on" , "Give extra importance to" , "Stress, underline" , "Mashes pie (anag.)" .)
