The term "mail flow" is a combination of two words: "mail" and "flow".
The word "mail" has its origins in the Old French word "male", which referred to a bag or a trunk. It later developed into the Middle English word "male", still signifying a bag or a wallet. Over time, "mail" came to specifically denote letters and packages sent through the postal system.
The word "flow" originated from the Old English word "flowan", meaning to flow or run smoothly. It can also be traced back to the Proto-Germanic word "flōaną" and the Proto-Indo-European root "pleu", both associated with the concept of flowing.
When combined, "mail flow" refers to the smooth and continuous movement of letters and packages through a postal system or any other means of mail delivery.
