The symposium was supported with funds from the Wenner-Gren Foundation. In the language of the Kom and Kshto tribes of eastern Nurist n, the root morpheme of a verbal form triggers the depiction of a force interacting with changing objects in a listener's cognitive image. A changing patient object is affected by the force, which may emanate from within the patient or externally from a changing agent object. If the verbal root depicts motion, the patient's destination and origin in the image are implied, along with an optional direction of motion. A root by itself or with remote agency suffixes is a verbal base .
Participles referring to feminine singular objects require a following feminine suffix -i .
A verbal base or participle is finite if it occurs after a specification of the objects to which it refers. Additionally, a finite form includes a subject-reference suffix when the object in subject focus is the speaker, listener, or plural. Finite verbal bases depict changes in an immediate mode that includes immediate actions and commands. Participles may be compounded with forms of the verb s'a- 'is' to depict a change's temporal distance from the time of speaking.
