PRONOUNS, PERSONAL. Them for they; us for weUs for we in "shall's." "Shall" (315), originally meaning necessity or obligation, and therefore not denoting an action on the part of the subject, was used in the South of England as an impersonal verb. (Compare Latin and Greek.) So Chaucer, "us oughte," and we also find "as us wol," i.e. "as it is pleasing to us." Hence in Shakespeare
“Shall's have a play of this?” Ib. v. 5. 28.
“Say, where shall's lay him?
“Shall's attend you there?
“Shall's to the Capitol?
