Citation, Documentation of Sources
Q. When can we use apud in a note?
A. Apud (Latin for “at,” “beside,” “within”) precedes the name of an author or title to indicate a source. It is used like the French word chez to mean “in the works of” or “according to”: apud Homer. It’s appropriate for those occasions when you just want to impress classics teachers or elderly readers and it doesn’t really matter whether anyone else understands.
