The Century Handbook of Writing Part 54

Note.--Very often the writer may choose freely between the semicolon and the period; in such instances the use of the semicolon implies greater logical unity between the clauses than the use of the period would show.

Unless this logical unity is distinct, the period is to be preferred.

=b. The semicolon is sometimes used between coordinate clauses which are joined by a conjunction if the clauses are long, or if the clauses have commas within themselves, or if obscurity would result were the semicolon not used.= (Otherwise, see 91a.)

Right: Very slowly the glow in the heavens deepened and extended itself along the eastern horizon; but at last the bright-red rim of the sun showed above the crest of the hill.

Right: He arrived, so they tell me, after nightfall; and immediately going to a hotel, called for a room.

Confusing: She enjoyed the dinners, and the dancing, and the music, and the whole gay round of fas.h.i.+onable life was a delight to her.

Better. She enjoyed the dinners, and the dancing, and the music; and the whole gay round of fas.h.i.+onable life was a delight to her.

=c. The semicolon is used between coordinate clauses which are joined by a formal conjunctive adverb (_hence_, _thus_, _then_, _therefore_, _accordingly_, _consequently_, _besides_, _still_, _nevertheless_, or the like).=

Wrong: We have failed in this therefore let us try something else.

Right: We have failed in this; therefore let us try something else.

Wrong: He was tattered and muddy, besides he ate like a cormorant.

Right: He was tattered and muddy; besides he ate like a cormorant.

Note 1.--If a simple conjunction like _and_ is used in the sentences above, a comma will suffice. But a comma is not sufficient before a conjunctive adverb like _therefore_. Conjunctive adverbs may be clearly distinguished from simple conjunctions (See 91a). They cannot always be easily distinguished from subordinating conjunctions (see 90b, Note), but the distinction, when it can be made with certainty, is an aid to clear thinking.

Note 2.--Good usage sometimes permits a comma to be used before a conjunctive adverb in short sentences where the break in the thought is not formal or emphatic. For instance, when the conjunctive adverb _so_ is used as a formal or emphatic connective, a semicolon is desirable (I won't go; so that's settled). But in the sentence, "I was excited, so I missed the target", a comma is sufficient. For the use of _so_ is here informal, and probably expresses degree as well as result. (Compare "I was so excited that I missed the target").

=d. The semicolon is not used before quotations, or after the "Dear Sir"

in letters. Use a comma or a colon.= (See 91h, 93a, and 87b.)

Wrong: Mother said; "Let me get my needle."

Right: Mother said, "Let me get my needle."

=The Colon=

=93a. The colon is used to introduce formally a word, a list, a statement or question, a series of statements or questions, or a long quotation.=
