re be more words than one, are in certain
cases separated from each other by the hyphen.

The numbers to which this rule applies are the cardinal and the
ordinal numbers from twenty-one and twenty-first to ninety-nine and
ninety-ninth inclusive. The hyphen is used also when the words are
inverted; as "four-and-thirty," "six-and-fortieth."

LXX. Fractional parts written in words are separated in the same way,
a hyphen being placed between the numerator and denominator; as
"two-thirds," "three-sixteenths."

But if the word "part" or the word "share" follows, the hyphen is not
used; as "two third parts."

LXXI. Several words may be joined by hyphens, in order to indicate
that they are to be read together.

The I-believe-of-Eastern-derivation monosyllable "Bosh."

Additional restrictions were advocated in the cases of
mothers-of-young-children employed in factories.

As this last sentence stands, the hyphen is really the only means of
making it perfectly clear that those who are referred to as employed
in factories are the mothers, not the children. Hyphens are sometimes
used in cases like the following: "A never-to-be-forgotten event,"
"peace-at-any-rate principles." They are almost invariably used in
"well-to-do," "alack-a-day."

LXXII. The prefix "a" before the gerund is followed by a hyphen.

They went a-hunting.

I lay a-thinking.

Note that "agoing" is not divided.

LXXIII. When a word is divided at the end of a line, part of the word
being in the next line, a hyphen is placed after the part at the end
of the line.

So far as rules can be given for the division of the word, it may be
said:

(_a_) The division must be at the end of a syllable. The syllable
according to etymological derivation, and the syllable according to
pronunciation, are not always the same. In case of conflict the
pronunciation is to be the guide.

(_b_) The part in the next line should, if possible, begin with a
consonant. An examination of a number of words will show that this is
only another way of saying that we should be guided by pronunciation.

(_c_) Double letters are divided; as "at-tract," "profes-sion,"
"dif-ficulty."

The following examples are given consecutively from a book taken at
random. This seems the best way of illustrating the rule:

Con-fidently; investi-gated; some-thing; institu-tion;
diffi-culty; at-tractions; exclu-sively; kins-man;
self-organized; e
