Actor Stonestreet (4)
I believe the answer is:
eric
'actor stonestreet' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eric that I've seen before include "Ancient blood-money; Ernie's partner" , "Boy's name" , "Cantona or Clapton?" , "--, or Little by Little (Dean Farrar)" , "Fine" .)
