A letter is a written or printed message that is typically sent from one person to another. It can be formal or informal and is often used for communication when a direct conversation is not possible. Letters are usually written on paper, but they can also be sent digitally through email or messaging platforms. They may convey personal thoughts, official information, requests, or invitations. Traditionally, letters were delivered by post or courier services, but with advancements in technology, electronic letters have become more common due to their speed and convenience.
