209. The Hyphen, or conjoiner -

is used to unite words which, though they are separate and distinct, have so close a connection as almost to become one word, as water-rat, wind-mill, &c. It is also used in writing and printing, at the end of a line, to show where a word is divided and continued in the next line. Look down the ends of the lines in this column, and you will notice the hyphen in several places.
