INTERJECTIONS are words which express the sudden emotions of the
speaker; as, "_Alas!_ I fear for life;" "_O_ death! where is thy sting?"
Interjections are not so much the signs of thought, as of feeling.
Almost any word may be used as an interjection; but when so employed, it
is not the representative of a _distinct_, idea. A word which denotes a
distinct conception of the mind, must necessarily belong to some other
part of speech. They who wish to speak often, or rather, to make
_noises_, when they have no useful information to communicate, are apt
to use words very freely in this way; such as the following expressions,
_la, la me, my, O my, O dear, dear me, surprising, astonishing_, and the
like.
Interjections not included in the following list, are generally known by
their taking an exclamation point after them.
