NOUNS

+21. Classes of Nouns.+--Nouns are divided into two general classes:
_proper_ nouns [Esther] and _common_ nouns [girl].

Common nouns include _abstract_ nouns [happiness] and _collective_ nouns
[army].

Any word mentioned merely _as a word_ is a noun: [_And_ is a conjunction].

+22. Inflection.+--A change in the form of a word to denote a change in
its meaning is termed _inflection_.

+23. Number.+--The most common inflection of the noun is that which shows
us whether the name denotes one or more than one. The power of the noun to
denote one or more than one is termed _number_. A noun that denotes but
one object is _singular_ in number. A noun that denotes more than one
object is _plural_ in number.

The plural number of nouns is regularly formed by adding _s_ and _es_ to
the singular [bank, banks; box, boxes].

Other points to be noted concerning the plural of nouns are as follows:--

1. The irregular plural in _en_ [child, children].

2. Formation of the plural by internal change [goose, geese].

3. Fourteen nouns ending in _f_ or _fe_ change the _f_ or _fe_ into _yes_
[leaf, leaves].

4. Nouns ending in _y_, preceded by a consonant, change the _y_ to _i_ and
add _es_ [enemy, enemies].

5. Letters, figures, signs, etc., form their plural by adding '_s_:[You
have used too many _i_'s].

6. Nouns taken from other lang
