"Aide" typically refers to a person who assists someone, often in a position of authority. For example:
* Presidential Aide: A person who assists the President.
* Teacher's Aide: A person who helps a teacher in the classroom.
To describe a document, you could use words like:
* Document
* Report
* Memorandum
* Briefing
* Manual
* Guide
Possible exceptions:
While uncommon, "aide" could be used metaphorically to describe a document that provides assistance in a particular situation. For example:
* "The legal team presented a helpful aide in the form of a detailed case brief."
However, this is not a standard use of the word and would be considered unconventional.
