Passive, causative and cooperative voices

A verb form expressing an action or state done together by more than one doer is in the cooperative voice. It is formed by adding -sh after a vowel and -ish after a consonant: ishla+sh, kel+ish: ishlashdi (worked together), kelishdi (came together). The cooperative often expresses the joint or mutual action of several people: gaplashdi (talked with each other), salomlashdi (greeted one another), yordamlashdi (helped each other). Sometimes it expresses plurality of doers: ular uyni supurishdi (they swept the house; each did his share).
