RULE VIII.—COMPOUNDS.
When any adjective or common noun is made a distinct part of a compound
proper name, it ought to begin with a capital; as, "The United States, the
Argentine Republic, the Peak of Teneriffe, the Blue Ridge, the Little
Pedee, Long Island, Jersey City, Lower Canada, Green Bay, Gretna Green,
Land's End, the Gold Coast."
RULE IX.—APPOSITION.
When a common and a proper name are associated merely to explain each other, it is in general sufficient, if the proper name begin with a capital, and the appellative, with a small letter; as, "The prophet Elisha, Matthew the publican, the brook Cherith, the river Euphrates, the Ohio river, Warren county, Flatbush village, New York city."
RULE X.—PERSONIFICATIONS.
The name of an object personified, when it conveys an idea strictly individual, should begin with a capital; as, "Upon this, Fancy began again to bestir herself."—Addison. "Come, gentle Spring, ethereal mildness, come."—Thomson.
RULE XI.—DERIVATIVES.
Words derived from proper names, and having direct reference to particular
persons, places, sects, or nations, should begin with capitals; as,
"Platonic, Newtonian, Greek, or Grecian, Romish, or Roman, Italic, or
Italian, German, or Germanic, Swedish, Turkish, Chinese, Genoese, French,
Dutch, Scotch, Welsh:" so, perhaps, "to Platonize, Grecize, Romanize,
Italicize, Latinize, or Frenchify."
RULE XII.—OF I AND O.
The words I and O should always be capitals; as, "Praise the Lord, O Jerusalem; praise thy God, O Zion."—Psalm cxlvii. "O wretched man that I am!"—"For that which I do, I allow not: for what I would, that do I not; but what I hate, that do I."—Rom., vii, 24 and 15.
