Introductory This book is intended for use in English courses in which the practice of composition is combined with the study of literature. It aims to give in brief space the principal requirements of plain English style. It aims to lighten the task of instructor and student by concentrating attention (in Chapters II and III) on a few essentials, the rules of usage and principles of composition most commonly violated. The numbers of the sections may be used as references in correcting manuscript. The book covers only a small portion of the field of English style, but the experience of its writer has been that once past the essentials, students profit most by individual instruction based on the problems of their own work, and that each instructor has his own body of theory, which he prefers to that offered by any textbook. The writer's colleagues in the Department of English in Cornell University have greatly helped him in the preparation of his manuscript. Mr. George McLane Wood has kindly consented to the inclusion under Rule 11 of some material from his Suggestions to Authors. The following books are recommended for reference or further study: in connection with Chapters II and IV, F. Howard Collins, Author and Printer (Henry Frowde); Chicago University Press, Manual of Style; T. L. De Vinne Correct Composition (The Century Company); Horace Hart, Rules for Compositors and Printers (Oxford University Press); George McLane Wood, Extracts from the Style-Book of the Government Printing Office (United States Geological Survey); in connection with Chapters III and V, Sir Arthur Quiller-Couch, The Art of Writing (Putnams), especially the chapter, Interlude on Jargon; George McLane Wood, Suggestions to Authors (United States Geological Survey); John Leslie Hall, English Usage (Scott, Foresman and Co.); James P. Kelly, Workmanship in Words (Little, Brown and Co.). It is an old observation that the best writers sometimes disregard the rules of rhetoric. When they do so, however, the reader will usually find in the sentence some compensating merit, attained at the cost of the violation. Unless he is certain of doing as well, he will probably do best to follow the rules. After he has learned, by their guidance, to write plain English adequate for everyday uses, let him look, for the secrets of style, to the study of the masters of literature. II. Elementary Rules of Usage   1. Form the possessive singular of nouns with 's. Follow this rule whatever the final consonant. Thus write, Charles's friend Burns's poems the witch's malice This is the usage of the United States Government Printing Office and of the Oxford University Press. Exceptions are the possessives of ancient proper names in -es and -is, the possessive Jesus', and such forms as for conscience' sake, for righteousness' sake. But such forms as Achilles' heel, Moses' laws, Isis' temple are commonly replaced by the heel of Achilles the laws of Moses the temple of Isis The pronominal possessives hers, its, theirs, yours, and oneself have no apostrophe.   2. In a series of three or more terms with a single conjunction, use a comma after each term except the last. Thus write, red, white, and blue honest, energetic, but headstrong He opened the letter, read it, and made a note of its contents. This is also the usage of the Government Printing Office and of the Oxford University Press. In the names of business firms the last comma is omitted, as Brown, Shipley and Company The abbreviation etc., even if only a single term comes before it, is always preceded by a comma.   3. Enclose parenthetic expressions between commas. The best way to see a country, unless you are pressed for time, is to travel on foot. This rule is difficult to apply; it is frequently hard to decide whether a single word, such as however, or a brief phrase, is or is not parenthetic. If the interruption to the flow of the sentence is but slight, the writer may safely omit the commas. But whether the interruption be slight or considerable, he must never omit one comma and leave the other. Such punctuation as Marjorie's husband, Colonel Nelson paid us a visit yesterday, or My brother you will be pleased to hear, is now in perfect health, is indefensible. Non-restrictive relative clauses are, in accordance with this rule, set off by commas. The audience, which had at first been indifferent, became more and more interested. Similar clauses introduced by where and when are similarly punctuated. In 1769, when Napoleon was born, Corsica had but recently been acquired by France. Nether Stowey, where Coleridge wrote The Rime of the Ancient Mariner, is a few miles from Bridgewater. In these sentences the clauses introduced by which, when, and where are non-restrictive; they do not limit the application of the words on which they depend, but add, parenthetically, statements supplementing those in the principal clauses. Each sentence is a combination of two statements which might have been made independently. The audience was at first indifferent. Later it became more and more interested. Napoleon was born in 1769. At that time Corsica had but recently been acquired by France. Coleridge wrote The Rime of the Ancient Mariner at Nether Stowey. Nether Stowey is only a few miles from Bridgewater. Restrictive relative clauses are not set off by commas. The candidate who best meets these requirements will obtain the place. In this sentence the relative clause restricts the application of the word candidate to a single person. Unlike those above, the sentence cannot be split into two independent statements. The abbreviations etc. and jr. are always preceded by a comma, and except at the end of a sentence, followed by one. Similar in principle to the enclosing of parenthetic expressions between commas is the setting off by commas of phrases or dependent clauses preceding or following the main clause of a sentence. The sentences quoted in this section and under Rules 4, 5, 6, 7, 16, and 18 should afford sufficient guidance. If a parenthetic expression is preceded by a conjunction, place the first comma before the conjunction, not after it. He saw us coming, and unaware that we had learned of his treachery, greeted us with a smile.   4. Place a comma before and or but introducing an independent clause. The early records of the city have disappeared, and the story of its first years can no longer be reconstructed. The situation is perilous, but there is still one chance of escape. Sentences of this type, isolated from their context, may seem to be in need of rewriting. As they make complete sense when the comma is reached, the second clause has the appearance of an after-thought. Further, and, is the least specific of connectives. Used between independent clauses, it indicates only that a relation exists between them without defining that relation. In the example above, the relation is that of cause and result. The two sentences might be rewritten: As the early records of the city have disappeared, the story of its first years can no longer be reconstructed. Although the situation is perilous, there is still one chance of escape. Or the subordinate clauses might be replaced by phrases: Owing to the disappearance of the early records of the city, the story of its first years can no longer be reconstructed. In this perilous situation, there is still one chance of escape. But a writer may err by making his sentences too uniformly compact and periodic, and an occasional loose sentence prevents the style from becoming too formal and gives the reader a certain relief. Consequently, loose sentences of the type first quoted are common in easy, unstudied writing. But a writer should be careful not to construct too many of his sentences after this pattern (see Rule 14). Two-part sentences of which the second member is introduced by as (in the sense of because), for, or, nor, and while (in the sense of and at the same time) likewise require a comma before the conjunction. If a dependent clause, or an introductory phrase requiring to be set off by a comma, precedes the second independent clause, no comma is needed after the conjunction. The situation is perilous, but if we are prepared to act promptly, there is still one chance of escape. For two-part sentences connected by an adverb, see the next section.   5. Do not join independent clauses by a comma. If two or more clauses, grammatically complete and not joined by a conjunction, are to form a single compound sentence, the proper mark of punctuation is a semicolon. Stevenson's romances are entertaining; they are full of exciting adventures. It is nearly half past five; we cannot reach town before dark. It is of course equally correct to write the above as two sentences each, replacing the semicolons by periods. Stevenson's romances are entertaining. They are full of exciting adventures. It is nearly half past five. We cannot reach town before dark. If a conjunction is inserted, the proper mark is a comma (Rule 4). Stevenson's romances are entertaining, for they are full of exciting adventures. It is nearly half past five, and we cannot reach town before dark. Note that if the second clause is preceded by an adverb, such as accordingly, besides, so, then, therefore, or thus, and not by a conjunction, the semicolon is still required. I had never been in the place before; so I had difficulty in finding my way about. In general, however, it is best, in writing, to avoid using so in this manner; there is danger that the writer who uses it at all may use it too often. A simple correction, usually serviceable, is to omit the word so, and begin the first clause with as: As I had never been in the place before, I had difficulty in finding my way about. If the clauses are very short, and are alike in form, a comma is usually permissible: Man proposes, God disposes. The gate swung apart, the bridge fell, the portcullis was drawn up.   6. Do not break sentences in two. In other words, do not use periods for commas. I met them on a Cunard liner several years ago. Coming home from Liverpool to New York. He was an interesting talker. A man who had traveled all over the world, and lived in half a dozen countries. In both these examples, the first period should be replaced by a comma, and the following word begun with a small letter. It is permissible to make an emphatic word or expression serve the purpose of a sentence and to punctuate it accordingly: Again and again he called out. No reply. The writer must, however, be certain that the emphasis is warranted, and that he will not be suspected of a mere blunder in punctuation. Rules 3,4, 5, and 6 cover the most important principles in the punctuation of ordinary sentences; they should be so thoroughly mastered that their application becomes second nature.   7. A participial phrase at the beginning of a sentence must refer to the grammatical subject. Walking slowly down the road, he saw a woman accompanied by two children. The word walking refers to the subject of the sentence, not to the woman. If the writer wishes to make it refer to the woman, he must recast the sentence: He saw a woman, accompanied by two children, walking slowly down the road. Participial phrases preceded by a conjunction or by a preposition, nouns in apposition, adjectives, and adjective phrases come under the same rule if they begin the sentence. On arriving in Chicago, his friends met him at the station. When he arrived (or, On his arrival) in Chicago, his friends met him at the station. A soldier of proved valor, they entrusted him with the defence of the city. A soldier of proved valor, he was entrusted with the defence of the city. Young and inexperienced, the task seemed easy to me. Young and inexperienced, I thought the task easy. Without a friend to counsel him, the temptation proved irresistible. Without a friend to counsel him, he found the temptation irresistible. Sentences violating this rule are often ludicrous. Being in a dilapidated condition, I was able to buy the house very cheap.   8. Divide words at line-ends, in accordance with their formation and pronunciation. If there is room at the end of a line for one or more syllables of a word, but not for the whole word, divide the word, unless this involves cutting off only a single letter, or cutting off only two letters of a long word. No hard and fast rule for all words can be laid down. The principles most frequently applicable are: a. Divide the word according to its formation: know-ledge (not knowl-edge); Shake-speare (not Shakes-peare); de-scribe (not des-cribe); atmo-sphere (not atmos-phere); b. Divide "on the vowel:" edi-ble (not ed-ible); propo-sition; ordi-nary; espe-cial; reli-gious; oppo-nents; regu-lar; classi-fi-ca-tion (three divisions possible); deco-rative; presi-dent; c. Divide between double letters, unless they come at the end of the simple form of the word: Apen-nines; Cincin-nati; refer-ring; but tell-ing. The treatment of consonants in combination is best shown from examples: for-tune; pic-ture; presump-tuous; illus-tration; sub-stan-tial (either division); indus-try; instruc-tion; sug-ges-tion; incen-diary. The student will do well to examine the syllable-division in a number of pages of any carefully printed book. III. Elementary Principles of Composition   9. Make the paragraph the unit of composition: one paragraph to each topic. If the subject on which you are writing is of slight extent, or if you intend to treat it very briefly, there may be no need of subdividing it into topics. Thus a brief description, a brief summary of a literary work, a brief account of a single incident, a narrative merely outlining an action, the setting forth of a single idea, any one of these is best written in a single paragraph. After the paragraph has been written, it should be examined to see whether subdivision will not improve it. Ordinarily, however, a subject requires subdivision into topics, each of which should be made the subject of a paragraph. The object of treating each topic in a paragraph by itself is, of course, to aid the reader. The beginning of each paragraph is a signal to him that a new step in the development of the subject has been reached. The extent of subdivision will vary with the length of the composition. For example, a short notice of a book or poem might consist of a single paragraph. One slightly longer might consist of two paragraphs: A. Account of the work. B. Critical discussion. A report on a poem, written for a class in literature, might consist of seven paragraphs: A. Facts of composition and publication. B. Kind of poem; metrical form. C. Subject. D. Treatment of subject. E. For what chiefly remarkable. F. Wherein characteristic of the writer. G. Relationship to other works. The contents of paragraphs C and D would vary with the poem. Usually, paragraph C would indicate the actual or imagined circumstances of the poem (the situation), if these call for explanation, and would then state the subject and outline its development. If the poem is a narrative in the third person throughout, paragraph C need contain no more than a concise summary of the action. Paragraph D would indicate the leading ideas and show how they are made prominent, or would indicate what points in the narrative are chiefly emphasized. A novel might be discussed under the heads: A. Setting. B. Plot. C. Characters. D. Purpose. A historical event might be discussed under the heads: A. What led up to the event. B. Account of the event. C. What the event led up to. In treating either of these last two subjects, the writer would probably find it necessary to subdivide one or more of the topics here given. As a rule, single sentences should not be written or printed as paragraphs. An exception may be made of sentences of transition, indicating the relation between the parts of an exposition or argument. In dialogue, each speech, even if only a single word, is a paragraph by itself; that is, a new paragraph begins with each change of speaker. The application of this rule, when dialogue and narrative are combined, is best learned from examples in well-printed works of fiction.   10. As a rule, begin each paragraph with a topic sentence; end it in conformity with the beginning. Again, the object is to aid the reader. The practice here recommended enables him to discover the purpose of each paragraph as he begins to read it, and to retain the purpose in mind as he ends it. For this reason, the most generally useful kind of paragraph, particularly in exposition and argument, is that in which a. the topic sentence comes at or near the beginning; b. the succeeding sentences explain or establish or develop the statement made in the topic sentence; and c. the final sentence either emphasizes the thought of the topic sentence or states some important consequence. Ending with a digression, or with an unimportant detail, is particularly to be avoided. If the paragraph forms part of a larger composition, its relation to what precedes, or its function as a part of the whole, may need to be expressed. This can sometimes be done by a mere word or phrase (again; therefore; for the same reason) in the topic sentence. Sometimes, however, it is expedient to precede the topic sentence by one or more sentences of introduction or transition. If more than one such sentence is required, it is generally better to set apart the transitional sentences as a separate paragraph. According to the writer's purpose, he may, as indicated above, relate the body of the paragraph to the topic sentence in one or more of several different ways. He may make the meaning of the topic sentence clearer by restating it in other forms, by defining its terms, by denying the converse, by giving illustrations or specific instances; he may establish it by proofs; or he may develop it by showing its implications and consequences. In a long paragraph, he may carry out several of these processes. 1 Now, to be properly enjoyed, a walking tour should be gone upon alone. 1 Topic sentence. 2 If you go in a company, or even in pairs, it is no longer a walking tour in anything but name; it is something else and more in the nature of a picnic. 2 The meaning made clearer by denial of the contrary. 3 A walking tour should be gone upon alone, because freedom is of the essence; because yo
