A memo, short for the word memorandum, comes from the Latin word memorandus, which means, to be remembered.. It is a compact written message designed to help someone remember something. For example, a list of groceries to be picked up on your way home from work is a memo, a simple list of things to be remembered later. Once acted upon, a memo is often thrown away. Not so with business memos. Unlike letters, the external communications of a company, business memos are an internal form of communication and it is standard practice to save them. Their objective is to deliver information or instructions and writing them is no-nonsense, nose to the grindstone writing.
