This is a deontic modal marker that modifies the third clause of the Kēlen rephrasal of the 1st article of the Universal Declaration of Human Rights. It usually translates as ‘should’, and indicates an admonishment to be as described in the third clause.
Is a commissive mood marker and commits the speaker (which in this context is the 1st person paucal/collective encompassing everyone) to do as described in the third clause. Since the 4th clause is subordinate to the third, it is included in this as well.
Confused yet? These two operate together to put a mild imperative and a should into the third clause, like so:
|therefore||should||we to each other||personhood||courtesies||from||one||to||other|
|therefore we should give to each other the courtesies of personhood|
|that||to them||to||weft-kin||to||them||their weft-kin||must|
|that are given to weft-kin and to their weft-kin|
And that concludes the Kēlen rephrasal of the 1st article of the Universal Declaration of Human Rights.
