Draconic language

Draconic was the language of dragons. It used its own distinct alphabet, called Iokharic. Other native speakers included members of draconic-related races, such as kobolds and dragonborn. The language was also used as a primary means of arcane notation throughout Toril.

Users
Draconic was one of the earliest languages, influencing or creating the language of kobolds and others. Draconic script was also used to write the elemental languages of Auran and Ignan.

The script was believed to have been influenced by the dwarven runes, but dragons themselves were unwilling to admit this connection.

Alphabet and punctuation
To give emphasis to important concepts, Iokharic employed a special character consisting of five lines radiating outwards, similar to an asterisk (*) or the five heads of Tiamat. When this character was written, the word was spoken with both the first and last syllables stressed. Dragons often used this when referring to themselves. Dragons also used it to command, warn, threaten, or otherwise make their point clear.

Basic grammar
Draconic was a language of hard consonants and sibilants that usually sounded like hissing when spoken, like sj, ss, and sv. It also included a sound similar to a creature clearing its throat, ach. jhvvbn
