Root Breakdown
Root-derived=memorandum
memorandum is Latin for 'a thing to be remembered' (the gerundive of memorare, 'to call to mind'). It's a note that exists precisely because memory fails — written down so it won't be forgotten. In offices it's a formal internal communication; in law and diplomacy a memorandum records an agreement.
