WORDS.

A WORD is a sign of an idea. It may be either spoken or written.

A PRIMITIVE, OR ROOT, word is one not derived from any other word of
the language; as, _fix_, _strike_, _man_.

A DERIVATIVE is a word formed from a primitive by changing it
internally, or by adding a prefix or suffix; as, _men_, _suffix_,
_strikers_.

A SIMPLE WORD is a single word. It may be either primitive or
derivative.

A COMPOUND WORD is a combination of two or more simple words; as,
buck-saw, well-behaved, school-room.

A word of one syllable is a _monosyllable_ (mono = one); of two
syllables, a _dissyllable_ (dis = two); of three syllables, a
_trisyllable_ (tri = three); of three or more syllables, a
_polysyllable_ (poly = many).

The ROOT of a word is its fundamental or elementary part which carries
the primitive notion or significance with it, without prefix or
suffix; as, _ge_ (earth), _graph_ (write), _vol_ (wish).

A PREFIX is a significant syllable joined to the beginning of a word;
as, _auto_graph, _circum_vent, _amphi_theater.

A SUFFIX is a significant syllable joined to the end of a word; as,
man _ly_, fert _ile_, ment _ion_.

AFFIX is a general term for prefixes and suffixes; it may be applied
to either or to both together.

SILENT LETTERS.

Silent letters have at least four uses:

1. To modify sounds of other letters in the same syllable.

Drop final silent _e_ from such words as the following and note the
effect on the sound of the other vowel in the same syllable: _bare_,
_pure_, _ripe_, _lame_.

2. To indicate pronunciation.

In the four words last given, for illustration, the pronunciation
changes when the final silent _e_ is dropped.

Another class of words ending in _ce_ and _ge_ retain the final silent
_e_ on adding a suffix beginning with _a_ or _o_ to preserve the soft
sound of _c_ and _g_, and with it the correct pronunciation of the
word; as, _serviceable_, _noticeable_, _changeable_, _courageous_.

3. To show the meaning of words.

Illustrations: _clime_, _climb_, _plumb_, _belle_, _butt_, _dyeing_,
_singeing_, _guilt_, _damn_.

4. To show the derivation of words.
