Name : Dita Wardhany Class : 3 C NPM : 10211210042 Compound Sentence A compound sentence is composed of at least two independent clauses. It does not require a dependent clause. The clauses are joined by a coordinating conjunction (with or without a comma), a correlative conjunction (with or without a comma), a semicolon that functions as a conjunction, or a conjunctive adverb preceded by a semicolon. A conjunction can be used to make a compound sentence. The use of a comma to separate two independent clauses is called a comma splice and is generally considered an error (when used in the English language). Compounding Sentence Elements Within a sentence, ideas can be connected by compounding various sentence elements: subjects, verbs, objects or whole predicates, modifiers, etc. Notice that when two such elements of a sentence are compounded with a coordinating conjunction (as opposed to the two independent clauses of a compound sentence), the conjunction is usually adequate and no comma is required. Subjects: When two or more subjects are doing parallel things, they can often be combined as a compounded subject. • Working together, President Jefferson and Meriwether Lewis convinced Congress to raise money for the expedition. Objects: When the subject(s) is/are acting upon two or more things in parallel, the objects can be combined. • President Jefferson believed that the headwaters of the Missouri reached all the way to the Canadian border. • He also believed that meant he could claim all that land for the United States. • President Jefferson believed that the headwaters of the Missouri might reach all the way to the Canadian border and that he could claim all that land for the United States. Notice that the objects must be parallel in construction: Jefferson believed that this was true and that was true. If the objects are not parallel (Jefferson was convinced of two things: that the Missouri reached all the way to the Canadian border and wanted to begin the expedition during his term in office.) the sentence can go awry.

Verbs and verbals: When the subject(s) is/are doing two things at once, ideas can sometimes be combined by compounding verbs and verb forms. • He studied the biological and natural sciences. • He learned how to categorize and draw animals accurately. • He studied the biological and natural sciences and learned how to categorize and draw animals accurately. Notice that there is no comma preceding the "and learned" connecting the compounded elements above. • In Philadelphia, Lewis learned to chart the movement of the stars. • He also learned to analyze their movements with mathematical precision. • In Philadelphia, Lewis learned to chart and analyze the movement of the stars with mathematical precision. • OR — In Philadelphia, Lewis learned to chart the stars and analyze their movements with mathematical precision. (Notice in this second version that we don't have to repeat the "to" of the infinitive to maintain parallel form.) Modifiers: Whenever it is appropriate, modifiers such as prepositional phrases can be compounded. • Lewis and Clark recruited some of their adventurers from river-town bars. • They also used recruits from various military outposts. • Lewis and Clark recruited their adventurers from river-town bars and various military outposts. Notice that we do not need to repeat the preposition from to make the ideas successfully parallel in form. Subordinating One Clause to Another The act of coordinating clauses simply links ideas; subordinating one clause to another establishes a more complex relationship between ideas, showing that one idea depends on another in some way: a chronological development, a cause-and-effect relationship, a conditional relationship, etc. • William Clark was not officially granted the rank of captain prior to the expedition's departure. • Captain Lewis more or less ignored this technicality and treated Clark as his equal in authority and rank. • Although William Clark was not officially granted the rank of captain prior to the expedition's departure, Captain Lewis more or less ignored this technicality and treated Clark as his equal in authority and rank. • The explorers approached the headwaters of the Missouri. • They discovered, to their horror, that the Rocky Mountain range stood between them and their goal, a passage to the Pacific. • As the explorers approached the headwaters of the Missouri, they discovered, to their horror, that the Rocky Mountain range stood between them and their goal, a passage to the Pacific. When we use subordination of clauses to combine ideas, the rules of punctuation are very important. It might be a good idea to review the definition of clauses at this point and the uses of the comma in setting off introductory and parenthetical elements. Using Appositives to Connect Ideas The appositive is probably the most efficient technique we have for combining ideas. An appositive or appositive phrase is a renaming, a re-identification, of something earlier in the text. You can think of an appositive as a modifying clause from which the clausal machinery (usually a relative pronoun and a linking verb) has been removed. An appositive is often, but not always, a parenthetical element which requires a pair of commas to set it off from the rest of the sentence. • Sacagawea, who was one of the Indian wives of Charbonneau, who was a French fur-trader, accompanied the expedition as a translator. • A pregnant, fifteen-year-old Indian woman, Sacagawea, one of the wives of the French fur-trader Charbonneau, accompanied the expedition as a translator. Notice that in the second sentence, above, Sacagawea's name is a parenthetical element (structurally, the sentence adequately identifies her as "a pregnant, fifteen-year-old Indian woman"), and thus her name is set off by commas; Charbonneau's name, however, is essential to the meaning of the sentence (otherwise, which fur-trader are we talking about?) and is not set off by a pair of commas.

Using Participial Phrases to Connect Ideas A writer can integrate the idea of one sentence into a larger structure by turning that idea into a modifying phrase. • Captain Lewis allowed his men to make important decisions in a democratic manner. • This democratic attitude fostered a spirit of togetherness and commitment on the part of Lewis's fellow explorers. • Allowing his men to make important decisions in a democratic manner, Lewis fostered a spirit of togetherness and commitment among his fellow explorers. In the sentence above, the participial phrase modifies the subject of the sentence, Lewis. Phrases like this are usually set off from the rest of the sentence with a comma. • The expeditionary force was completely out of touch with their families for over two years. • They put their faith entirely in Lewis and Clark's leadership. • They never once rebelled against their authority. • Completely out of touch with their families for over two years, the men of the expedition put their faith in Lewis and Clark's leadership and never once rebelled against their authority. Using Absolute Phrases to Connect Ideas Perhaps the most elegant — and most misunderstood — method of combining ideas is the absolute phrase. This phrase, which is often found at the beginning of sentence, is made up of a noun (the phrase's "subject") followed, more often than not, by a participle. Other modifiers might also be part of the phrase. There is no true verb in an absolute phrase, however, and it is always treated as a parenthetical element, an introductory modifier, which is set off by a comma. The absolute phrase might be confused with a participial phrase, and the difference between them is structurally slight but significant. The participial phrase does not contain the subject-participle relationship of the absolute phrase; it modifies the subject of the the independent clause that follows. The absolute phrase, on the other hand, is said to modify the entire clause that follows. In the first combined sentence below, for instance, the absolute phrase modifies the subject Lewis, but it also modifies the verb, telling us "under what conditions" or "in what way" or "how" he disappointed the world. The absolute phrase thus modifies the entire subsequent clause and should not be confused with a dangling participle, which must modify the subject which immediately follows. • Lewis's fame and fortune was virtually guaranteed by his exploits. • Lewis disappointed the entire world by inexplicably failing to publish his journals. • His fame and fortune virtually guaranteed by his exploits, Lewis disappointed the entire world by inexplicably failing to publish his journals. • Lewis's long journey was finally completed. • His men in the Corps of Discovery were dispersed. • Lewis died a few years later on his way back to Washington, D.C., completely alone. • His long journey completed and his men in the Corps of Discovery dispersed, Lewis died a few years later on his way back to Washington, D.C., completely alone.
