Unlike nouns, most of the personal pronouns have distinct forms for the nominative and the objective.

Note. The possessive case of personal pronouns never has the apostrophe. Thus,—its, yours, theirs.

The form it’s is proper only as a contraction of it is.

GENDER AND NUMBER

116. The pronouns of the first and second persons (I and thou) may be either masculine or feminine.

The pronouns of the third person have different forms for masculine, feminine, and neuter in the singular (he, she, it); but in the plural the form they serves for all three genders.
