Each verb stem has an unpredictable inherent aspect value (either telic or atelic; by default, a bare stem is inherently atelic), and an inherent value for transitivity (transitive, intransitive or impersonal). The inherent values can be changed by morphological addition to yield a verb stem with any of the other possible values.
Each verb root has an unpredictable intrinsic quality (either telic or atelic; by default, a bare stem is inherently atelic), and an inherent value for transitivity (transitive, intransitive, or impersonal). The intrinsic qualities can be modified through morphological additions to produce a verb stem with any of the other possible values.
