The verb cluster

Use of modal particles

Pos conveys an idea of ability, capability, that the subject knows how to do something, both an innate or a learnt capability.

• Tȳn nat lā pos: He cannot write (for example, because the subject is too young, and still does not know how to write)

Kra conveys an idea of a momentaneous ability, something that the subject can do in this moment, not a forever real capability.

• Tȳn nat lā kra sty: He cannot write (for example, the subject is too excited to write, too cold or too frightened, a momentaneous condition, but he knows how to write)
