LXV. Names of newspapers and magazines, and names of ships, are generally written in italics; as the Times, the Fort-nightly Review, the Great Eastern.
THE HYPHEN
LXVI. The hyphen is used between the component parts of some compound words.
Paper-knife; book-keeping; coal-pit; water-carrier; printing-press; sea-water; man-of-war; now-a-days; high-art decoration; good-looking.
There is no rule to distinguish the compound words that take a hyphen from those that do not. If one be in doubt about a particular word, the best thing to do is to refer to a dictionary.
LXVII. When one syllable of a word ends with a vowel, and the next syllable begins with the same vowel, the hyphen is placed between the syllables to indicate that the two vowels do not form a diphthong, that is, that they should not be pronounced together.
Co-operative; co-ordinate; pre-eminently; re-establish; re-echo.
In the same way the hyphen sometimes ensures that two consonants shall be pronounced separately; as in "book-keeping," "shell-less," "cock-crow," "sword-dance."
