A Word is either a syllable or a combination of syllables; as, not,
notion.

A word of one syllable is called a Monosyllable; as, man.

A word of two syllables is called a Dissyllable; as, manly.

A word of three syllables is called a Trisyllable; as, manliness. Words of
more than three syllables are called Polysyllables.

Accent is a stress of voice placed upon some one syllable more than the
others. Every word composed of two or more syllables has one of them
accented. This accent is denoted by a mark (') at the end of the accented
syllable; as, mid'night, a ban'don.

A Primitive Word is one which is not derived from any other word; as, man,
great, full.

A Derivative Word is one which is formed from some other word by adding
something to it; as, manful, greatness, fully.

A Simple Word is one which is not composed of more than one word; as,
kind, man, stand, ink.

A Compound Word is one that is composed of two or more simple words; as,
ink-stand, wind-mill.

Spelling is naming or writing the letters of a word.
