Celinese: Nominal Categories: Politeness Distinctions in Pronouns: Pronouns avoided for politeness
Because the conjugation system makes the subject of each verb clear, pronouns generally are only used for distinction:
Thon esfotheg né syrís; mair [sé] syrí ais. You don't like Jinyer food, but /I/ do [like it].
As a consequence, using a pronoun in a non-comparative sentence sounds brusque, particularly when used with a request, and is avoided.
Tyllús mair ana! - "bequiet.SBJV-2SG but you" would usually be translated as "shut up."
