K3 persons

K3 doesn't make the conventual 1st and 2nd person distinction; instead it makes a distinction between knower and learner. The knower, or K person, refers to the speaker(s) in statements but to the addressee(s) in questions and commands, while the learner, or L person, refers to the addressee(s) in statements but to the speaker(s) in questions and commands. Both K and L persons distinguish singular and plural. Note that "speakers" and "addressees", when plural, may include associated persons, but are mutually exclusive. There's also an inclusive, or N person, that refers to the speakers and addressees together and is only plural.

The 3rd person is conventual but the distinction made is not number (singular and plural) but definite and indefinite.
