A memorandum is a written document used to communicate information, instructions, proposals, or decisions within an organization or between related parties. It serves as an institutional record — a formalized shorthand for organizational memory that persists through filing systems, institutional memory practices, and the written word. A memorandum has a standardized structure: recipient, sender, date, subject, and body — and its authority comes from the institutional position of its author, not from any external enforcement mechanism.

Memorandum is a formal written message — it cannot exist without writing as its substrate and mechanism. Remove writing and the memorandum ceases to operate.

Direction tested: INSTANCE_OF (specific→general). A memorandum IS a specific kind of communication — a formal written message used within organizations. The sense pinned is the document-as-communication-act: a memorandum is a structured form of written communication, designed to convey information officially. A competent speaker would describe a memo as 'a type of communication.' Removal test doesn't apply here; this is a kind-of relationship.
