Phonology
The phonology of the Yazgulyam language differs from the basic "Shugni-Roshani" type its system of dorsal consonants: In addition to the velar and uvular stops g, k, q and fricatives x̌, γ̌, x, γ,, Yazgulami has a palatalized and a labialized series, transcribed as ḱ, ǵ (palatalized velars), k° g° x̌° (labialized velars, there is no labialized velar voiced fricative) and q° x° γ° (labialized uvulars). A significant number of labialized consonants etymologically correspond to Proto-Iranian *Cv or *Cu, e.g. x̌°arg < *hvaharā- "sister", while others are unrelated to Proto-Iranian v, e.g. sk°on < skana- "puppy".
This threefold system of articulation of dorsals has been compared typologically to the three reconstructed rows of dorsals in the Proto-Indo-European language.
