Sidetic is a right-to-left alphabet that was used from the 5th through 2nd centuries BCE for writing a now-extinct Indo-European language of the Anatolian branch, which is also referred to by scholars as ‘Sidetic’ (ISO 639: xsd).

The script is attested on 10 stone inscriptions and a number of coins. However, it has not been fully deciphered. Scholars have identified at least 29 distinctive letters. There is some consensus on the values of 26 letters. The values of the other 3 letters are unclear. Of these 26 letters, there are 5 vowel letters, 2 semi-vowels, and 19 consonants.
