The possessive pronouns, like other adjectives, are without cases or change

separated by a verb, as These are our books. These books are ours. Your
children excel ours in stature, but ours surpass yours in learning.

Ours, yours, hers, theirs, notwithstanding their seeming plural

substantive preceding, as thy house is larger than mine, but my garden
is more spacious than thine.

Their and theirs are the possessives likewise of they, when they is the
plural of it, and are therefore applied to things.

Pronouns relative are, who, which, what, whether, whosoever, whatsoever.

Whose is rather the poetical than regular genitive of which.

Brought death into the world. Milton.

Whether is only used in the nominative and accusative cases; and has no
