more. The plural is generally formed from the singular by the addition of
_s_ or _es_.

_Gender_ has the same relation to nouns that sex has to individuals, but
while there are only two sexes, there are four genders, viz., masculine,
feminine, neuter and common. The masculine gender denotes all those of
the male kind, the feminine gender all those of the female kind, the
neuter gender denotes inanimate things or whatever is without life, and
common gender is applied to animate beings, the sex of which for the time
being is indeterminable, such as fish, mouse, bird, etc. Sometimes things
which are without life as we conceive it and which, properly speaking,
belong to the neuter gender, are, by a figure of speech called
Personification, changed into either the masculine or feminine gender,
as, for instance, we say of the sun, _He_ is rising; of the moon, _She_
is setting.

_Case_ is the relation one noun bears to another or to a verb or to a
preposition. There are three cases, the _Nominative_, the _Possessive_
and the _Objective_. The nominative is the subject of which we are
speaking or the agent which directs the action of the verb; the
possessive case denotes possession, while the objective indicates the
person or thing which is affected by the action of the verb.

An _Article_ is a word placed before a noun to show whether the latter is
used in a particular or general sense. There are but two articles, _a_ or
_an_ and _the_.

An _Adjective_ is a word which qualifies a noun, that is, which shows
some distinguishing mark or characteristic belonging to the noun.
