Alias preceder (3)
I believe the answer is:
aka
'alias preceder' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aka that I've seen before include "Notation indicating alias or other name" , "Using the byline" , "Notation with initials indicating alternative name" , "Also called (abbrev.)" , "Also known as, initially" .)
