What is a letter?
In the literary Russian of the 18th century, the very word"Letter" expressed the general meaning: composition, work. And under the great influence of the Polish-language vocabulary in Russian in the 18th century, perhaps "writing" as a word meant not only litterae (writing, letters), but also opus.
What is a letter in fact?
A letter is a postal item in the form ofa written message, possibly with another investment that is intended for the exchange of various information between people.

This makes it possible to transmit various information over long distances.
Today the letter retained its main functionand carries, in the first place, information purpose. Only the method of transferring the letter has changed: it is an electronic way, for example, using e-mail.
