II.—ETYMOLOGICAL CLASSES OF WORDS.
Оглавление10. Classes by Origin.—With respect to their origin, words are divided into two classes—primitive words and derivative words.
11. A primitive word, or root, is one that cannot be reduced to a more simple form in the language to which it is native: as, man, good, run.
12. A derivative word is one made up of a root and one or more formative elements: as, manly, goodness, runner.
The formative elements are called prefixes and suffixes. (See §§ 16, 17.)
13. By Composition.—With respect to their composition, words are divided into two classes—simple and compound words.
14. A simple word consists of a single significant term: as, school, master, rain, bow.
15. A compound word is one made up of two or more simple words united: as, school-master, rainbow.
In some compound words the constituent parts are joined by the hyphen as school-master; in others the parts coalesce and the compound forms a single (though not a simple) word, as rainbow.
