Draconic is one of the oldest languages, influencing or creating the language of kobolds and other races. Those growing up in Dragonborn culture tend to learn it as a proud part of their heritage.
According to dragons, their language was the oldest mortal tongue and all other mortal languages descended from it.
Draconic is a monolithic language, and it remains almost unchanged since its creation. This has left it a language studied mostly by historians and archeologists; magical studies tend to use more expanded and extensive languages.
