Adjective pronouns belong to nouns, expressed or understood; as, "Any man, all men."
NOTE 1. The demonstrative adjective pronouns must agree in number with their nouns; as, "This book, these books; that sort, those sorts."
2. The pronominal adjectives, each, every, either, neither, another, and one, agree with nouns in the singular number only; as, "Each man, every person, another lesson;" unless the plural nouns convey a collective idea: as, "Every six months."
3. Either is often improperly employed instead of each; as, "The king of Israel, and Jehoshaphat the king of Judah, sat either of them on his throne." Each signifies both taken separately; either implies only the one or the other taken disjunctively:—"sat each on his throne."
