DEFINITIONS

A _Pronoun_ is a word used for or instead of a noun to keep us from
repeating the same noun too often. Pronouns, like nouns, have case,
number, gender and person. There are three kinds of pronouns, _personal_,
_relative_ and _adjective_.

A _verb_ is a word which signifies action or the doing of something. A
verb is inflected by tense and mood and by number and person, though the
latter two belong strictly to the subject of the verb.

An _adverb_ is a word which modifies a verb, an adjective and sometimes
another adverb.

A _preposition_ serves to connect words and to show the relation between
the objects which the words express.

A _conjunction_ is a word which joins words, phrases, clauses and
sentences together.

An _interjection_ is a word which expresses surprise or some sudden
emotion of the mind.
