What is the letter
A letter is a written message from one party to another containing information. Letters promote the preservation of communication between both parties; they may bring friends or relatives closer together, enrich professional relationships and provide a means of self-expression. Letters contribute to the protection and conservation of literacy.[1] Letters have been sent since antiquity and are mentioned in the Iliad.[2] Works by both Herodotus and Thucydides also mention letters.
