"Juliet, retain her paper, and present _yours_."
_Yours_ is a compound personal pronoun, representing both the possessor
and the thing possessed, and is equivalent to _your paper_. _Your_ is a
pronoun, a word used instead of a noun--personal, it personates
"Juliet"--second person, it represents the person spoken to--fem.
gender, sing. number, (singular in sense, but _plural_ in form,) because
the noun Juliet is for which it stands: Rule 13. _Pers. Pron.
&c_.--_Your_ is in the possessive case, it denotes possession, and is
governed by "paper," according to Rule 12. _A noun or pron. &c._ (Repeat
the Rule, and decline the pronoun.) _Paper_ is a noun, the name of a
thing--common, the name of a sort of things--neuter gender, it denotes a
thing without sex--third person, spoken of--sing. number, it implies but
one--and in the obj. case, it is the object of the action expressed by
the transitive verb "present," and governed by it: Rule 20.
_Active-transitive verbs govern the obj. case_.
NOTE. Should it be objected, that _yours_ does not mean _your paper_,
any more than it means _your book, your house, your_ any thing, let it
be borne in mind, that pronouns have no _definite_ meaning, like other
words; but their _particular_ signification is always determined by the
nouns they represent.
