+56.+ There is another class of words which we use _with_ sentences, but
which are really not _parts_ of the sentences. They are emotional
expressions which seem to belong more to the natural language than to
the invented language. For example:
Oh! You hurt me!
Aha! Now I have you.
_Oh_, used in this way, is very apt to sound like a groan, and _aha_
like a shout of triumph. These words do not really belong in the
construction of the sentence. The sentence would be complete without
them, but they are thrown in to express the emotion which accompanies
the thought. We call expressions such as these _interjections_.
Interjection is from the Latin and means literally _thrown into the
midst of_. It comes from the Latin word _inter_, which means _between_,
and the Latin verb _jecto_, _to throw_, so it literally means _to throw
between_.
Some of these words imitate sounds, as for example:
Bang! There goes another shot.
Ding-dong! There goes the first bell.
We do not use interjections very frequently in writing on scientific
subjects that express deep thought, but you will find them often used in
poetry, fiction, oratory or any emotional writing. Therefore we have our
definition of an interjection:
+57.+ +An interjection is an exclamatory word or phrase used to express
feeling or to imitate some sound.+
+58.+ Following is a list of commonly used interjections. Use them in
sentences of your own.
