Tau gallicum

The name ARAꟇꟇOVNA on a Gallic tomb.

Tau gallicum, or D with short stroke overlay in Unicode, (majuscule: Ꟈ (), minuscule: ꟈ ()) is a letter that was used to write the Gaulish language.[1] It is a D with the horizontal bar from the Greek letter Θ.[1] It likely represented a /t͡s/ or /st/ sound,[1] like the ts in cats or the st in stop. In modern times, it is used in the Cubeo and Daasanach languages to represent the sound [ð], in the Northern Embera language to represent the sound [ɗ], and in the Moro language.
