Opening made by author if I censor piece (7)
I believe the answer is:
orifice
'opening' is the definition.
(I know that opening can be written as orifice)
'author if i censor piece' is the wordplay.
'piece' says the answer is hidden in the clue.
'ORIFICE' is hidden in the letters of 'author if i censor'.
'made by' acts as a link.
(Other definitions for orifice that I've seen before include "8 [OPENING]" , "Bodily opening, mouth of cavity" , "Mouth-like opening" , "Vent" , "Finding opening" .)
