LANGUAGE is the expression of thought by means of words.
WORDS, with respect to their _origin_, are divided into _primitive_
and _derivative_; and with respect to their _composition_, into _simple_
and _compound_.
A PRIMITIVE word is one that is not derived from another word.
A DERIVATIVE word is one that is formed from another word by means
of prefixes or suffixes, or by some other change.
A SIMPLE word is one that consists of a single significant term.
A COMPOUND word is one made up of two or more simple words.
A SENTENCE is a combination of words which make complete sense.
A SYLLABLE is a word or a part of a word pronounced by one effort
of the voice.
The DIAERESIS is the mark [..] placed over the second of two
adjacent vowels, to denote that they are to be pronounced as distinct
letters; as _REËCHO_.
