This compiler's role editor communicated (8)
I believe the answer is:
imparted
'communicated' is the definition.
(imparting is a kind of communicating)
'this compiler's role editor' is the wordplay.
'this compiler's' becomes 'I'm' ('I'm', referring to the crossword compiler).
'role' becomes 'part' (eg a part or role in a film).
'editor' becomes 'ed' (abbreviation).
'im'+'part'+'ed'='IMPARTED'
(Other definitions for imparted that I've seen before include "Conveyed knowledge" , "Related" , "Transmitted knowledge" , "Revealed or made known to" , "Communicated (information)" .)
