equally apparent, that walk is _plural_, because it expresses _two_
actions? In the sentence, Ten men _walk_, the verb _walk_ denotes _ten_
actions, for there are ten actors. Common sense teaches you, that there
must be as many _actions_ as there are _actors_; and that the verb, when
it has _no form_ or _ending_ to show it, is as strictly plural, as when
it has.--So, in the phrase, _We_ walk, the verb walk is _first_ person,
because it expresses the actions performed by the _speakers: Ye_ or
_you_ walk, the verb is _second_ person, denoting the actions of the
persons _spoken to;_ third person, _They_ walk. The verb, then, when
correctly written, always agrees, in _sense_, with its nominative in
number and person.

At present you are learning two parts of speech, neither of which can be
understood without a knowledge of the other. It therefore becomes
necessary to explain them both, in the same lecture. You have been
already informed, that nouns have three cases; the nominative, the
possessive, and the objective.

POSSESSIVE CASE. The _possessive case_ denotes the possessor of
something; as, This is _John's_ horse. This expression implies, that
_John_ is the _owner_ or _possessor_ of the horse; and, that horse is
the _property_ which he possesses.

When I say, These are the _men's_, and those, the _boys'_ hats, the two
words, "boys' hats," plainly convey the idea, if they have any meaning
at all, that the boys _own_ or _possess_ the hats. "Samuel Badger sells
_boys'_ hats." Who _owns_ the hats? Mr. Badger. How is that fact
ascertained? Not by the words, "boys' hats," which, taken by themselves,
imply, not that they are _Mr. Badger's_ hats, nor that they are _for_
boys, but that they are hats _of_, or _belonging to_, or _possessed by_
