memorandum
or memo
what is a memo?
A memorandum (abbrev.: memo) was from the Latin verbal phrase memorandum est, the gerundive form of the verb memoro, "to mention, call to mind, recount, relate",[1] which means "It must be remembered (that)...". It is therefore a note, document or other communication that helps the memory by recording events or observations on a topic, such as may be used in a business office. The plural form of the Latin noun memorandum so derived is properly memoranda, but if the word is deemed to have become a word of the English language, the plural memorandums, abbreviated to memos, may be used. (See also Agenda, Corrigenda, Addenda)
structure
All memos are structured similarly. They have the following elements:
•An addressee: Flush left, in capital letters, near the top of the page
•The sender: Flush left, in caps, immediately below the addressee
•Date: Flush left, in caps, immediately below the sender’s name
•Subject: Flush left, in caps, immediately below the date
