Sentence parts include: Exploring Sentence Structure Art Lightstone Mastering the use of one‟s own language, both written and verbal, is probably the single most effective thing one can do to ensure their academic, professional, and personal success. Sentence Types • subject • predicate • clause (main, subordinate, relative, noun) • phrase • object Sentence structures include: • simple • compound • complex • compound-complex Sentence types include: • declarative • interrogative • imperative • exclamatory Declarative Sentences • A declarative sentence is used to make a statement. • It's lunch time. • An interrogative sentence is used to pose a question. • We are going to the game on Friday. • An imperative sentence is used to give a command or to implore or entreat. • My car is out of gasoline. • An exclamatory sentence is used to express astonishment or extreme emotion. Most of the sentences we speak or write are declarative sentences. Interrogative sentences • What time does the movie start? • How many people from your graduating class went to college? • Is there a reason why these dirty clothes are in the middle of the floor? • What are they serving in the cafeteria today? • My parents keep telling me that I should make good grades so I can get a job or go to college. • We frequently ask questions, perhaps not as frequently as we should. Imperative sentences People who have authority use imperative sentences. Sometimes, people who don't have authority use imperative sentences. The results may differ. • Wash the car. • Clean up your room. • Martin, report to the counsellor. • Please donate to the community charity fund. We say that sentences must have a subject and a verb. Note that some of the above sentences do not seem to have a subject. The subject is implied, and the implied subject is you. You wash the car. You clean up your room. “You” is a second person pronoun. It isn't possible to make a command statement in first person or third person. 1 Exclamatory Sentences Exclamatory sentences are rarely used in expository writing. Spoken exclamations are often a single word or an incomplete sentence. Grammarians indicate that formal exclamatory sentences begin with the word what or with the word how. Most of the exclamations we encounter are informal. • What a beautiful night! • How happy we were when the dawn came and our flag was still there! • What did you do to your hair?! (exclamation formed as a question) Before we continue, it is important to distinguish between the “parts of speech” and the “parts of a sentence.” In examining parts of speech we focus on words and phrases and their relationships to each other. In examining parts of a sentence we focus on words and phrases and their relationships to the thought, or thoughts, being expressed in the sentence. Parts of a sentence include the subject, predicate, object, clause, and phrase. A sentence can be defined as a group of words containing a subject and a predicate and expressing a complete thought. • I just won 500 dollars! (exclamation formed as a declarative sentence) Parts of a Sentence Independent Clause Subject: The subject or of a sentence is the noun, pronoun or noun phrase that precedes and governs the main verb. The subject is what (or whom) the sentence is about. (The party who performs the action, or being described.) Predicate: Tells something about the subject. It is the verb and any complement of the verb, which can include the object, adverbial, etc. (The action or description.) Object: Part of the predicate, the object is the person or thing that is created, affected or altered by the action of a verb, or appreciated or sensed by the subject of the verb. (The party that is acted upon.) Clause: A group of words containing a subject and verb. If the clause completes a thought, then it is an independent clause (aka main or principle). If a clause does not complete a thought, then it is a dependent clause (aka subordinate). An independent clause includes a subject and a verb. An independent clause is a clause that is not introduced by a subordinating term. An independent clause is the main idea of the sentence and is not dependent on another clause for meaning and context. It does not modify anything, and it can stand alone as a complete sentence. Independent clauses are sometimes called principal or main clauses. Example: The hungry boy whispered to his sister because his throat hurt. The underlined portion of the above sentence is an independent clause. Phrase: A phrase is a group of words acting together as a single part of speech. A phrase does not contain both a subject and a verb. Subordinate Clause The Relative Clause A subordinate clause is usually introduced by a subordinating element such as a subordinating conjunction or relative pronoun. It depends on the rest of the sentence for its meaning. It does not express a complete thought, so it does not stand alone. It must always be attached to a main clause that completes the meaning. Subordinate clauses normally act as single part of speech. They can be either noun clauses, adjective clauses, or adverb clauses. They are sometimes called dependent clauses because they "depend" on a main clause to give them meaning. The italicised clauses above are subordinate clauses. The first one is an adjective clause because it describes a noun (the word clause). The second one is an adverb clause which describes a verb (the word called). Example: The hungry boy whispered to his sister because his throat hurt. A relative clause (aka adjective or adjectival clause) is a type of subordinate clause that has three characteristics: 1. It will contain a subject and verb. 2. It will begin with a relative pronoun [who, whom, whose, that, or which] or a relative adverb [when, where, or why]. 3. It will function as an adjective, answering the questions What kind? How many? or Which one? The relative clause will follow one of these two patterns: relative pronoun or adverb + subject + verb relative pronoun as subject + verb (Some grammarians argue that this structure produces an incomplete thought.) The underlined portion of the above sentence is a dependent clause. 2 Examples of Relative Clauses … which Francine did not accept. which = relative pronoun; Francine = subject; did not accept = verb [not, an adverb, is not officially part of the verb]. …where George found Amazing Spider-Man #96 in fair condition. where = relative adverb; George = subject; found = verb. …that dangled from the one clean bathroom towel. that = relative pronoun functioning as subject; dangled = verb. …who continued to play video games until his eyes were blurry with fatigue Avoid Creating a Sentence Fragment. A relative clause does not express a complete thought, so it cannot stand alone as a sentence. To avoid writing a fragment, you must connect each relative clause to a main clause. Read the examples below. Notice that the relative clause follows the word that it describes. To calm his angry girlfriend, Joey offered an apology which Francine did not accept. We tried our luck at the same flea market where George found Amazing Spider-Man #96 in fair condition. Michelle screamed when she saw the spider that dangled from the one clean bathroom towel. who = relative pronoun functioning as subject; played = verb. Brian said goodnight to his roommate Justin, who continued to play video games until his eyes were blurry with fatigue. Punctuating Relative Clauses: Restrictive or Non-Restrictive? Punctuating relative clauses can be tricky. For each sentence, you will have to decide if the relative clause is essential or nonessential and then use commas accordingly. Noun Clauses Any clause (grouping of subject and verb) that functions as a noun in the larger sentence becomes a noun clause. Restrictive (aka essential) clauses do not require commas. A relative clause is restrictive when you need the information it provides. Consider this example: Consider this example: You really do not want to know the ingredients in Aunt Nancy's stew. The children who skateboard in the street are especially noisy in the early evening. “ingredients” = noun. Children is non-specific. To know which ones we are talking about, we must have the information in the relative clause. Thus, the relative clause is restrictive and requires no commas. If we replace the noun ingredients with a clause, we have a noun clause: If, however, we eliminate children and choose more specific nouns instead, the relative clause becomes nonessential and does require commas to separate it from the rest of the sentence. Read this revision: You really do not want to know what Aunt Nancy adds to her stew. “what Aunt Nancy adds to her stew” = noun clause. Matthew and his sister Loretta, who skateboard in the street, are especially noisy in the early evening. Differentiating Subjects from Objects Sidebar Beginning a Sentence with Because The notion that one should not begin a sentence with because retains a mysterious grip on people's sense of writing proprieties. This might come about because a sentence that begins with because could well end up a fragment if one is not careful to follow up the subordinate clause with an independent clause. Because is a subordinating conjunction - used to introduce a subordinating clause. A subordinating conjunction can begin a sentence by introducing a subordinate clause. As long as the thought is then completed by an independent clause, the sentence will be grammatically correct. A subject acts, and an object is acted upon. Subject and Object Pronouns: In English, we have different pronouns to signify the distinction between those grammatical categories. In other words, "I" is a subject while "me" is an object while "my" shows possession; "we" is a subject while "us" is an object and "our" shows possession. Because the students studied grammar. Because the students studied grammar, their writing improved. Although it is true that beginning a sentence with because might produce a dependent clause fragment, similar taboos have never been associated with other subordinating conjunctions such as Although, If, When, While, and Since. It is unclear why the word because has been singled out for this dubious distinction. 3 Differentiating Clauses from Phrases Clause: “cows eat grass” This example is a clause because it contains the subject "cows" and the verb "eat grass." Phrase: “cows eating grass” This example is a phrase because it does not contain a subject and a verb. In this case, “eating grass” serves as an adjective phrase that is part of a larger noun phrase. The reader is left wondering, “What about the „cows eating grass‟?” While this noun phrase could be a subject, it has no verb attached to it. The adjective phrase "eating grass" show which cows the writer is referring to, but there is nothing here to show why the writer is mentioning cows in the first place. Restrictive versus Non-restrictive Clauses Restrictive clauses: A restrictive clause will limit the possible meaning of a preceding subject. Example: The suspect who has red hair committed the crime. Note how the subject "suspect" in this sentence is restricted, or clearly identified, by the restrictive clause. It is not just any suspect who committed the crime, it is the suspect with red hair. Parenthetical Clauses and Phrases A parenthetical clause or phrase provides additional information for the reader, but it is information that could be left out of the sentence without altering its basic message. Example: The practice of teaching grammar, originally pursued by only a few English teachers, has now become standard practice in all Grade 12 courses. Example: The teachers in the Bjork board, although understaffed and under funded, manage to maintain orderly and effective learning environments. In each of the above examples, the words between the commas could be left out without changing the core meaning of the sentence. Including a parenthetical clause allows the writer to add ancillary information without writing a separate sentence. After all, if separate but related concepts were always separated out into their own sentences, one‟s writing would become extremely choppy and mechanical. More Examples of Restrictive Clauses • Students who cheat only harm themselves. • The baby wearing a yellow jumpsuit is my niece. • The candidate who had the least money lost the election. More Examples of Non-restrictive Clauses Non-Restrictive Clauses: While non-restrictive clauses will tell us additional information about a preceding subject, they do not limit or specifically identify that subject. • Fred, who often cheats, is just harming himself. Example: The suspect in the lineup, who owns a red car, committed the crime. • The Green party candidate, who had the least money, lost the election. • My niece, wearing a yellow jumpsuit, is playing in the living room. Note how the subject "suspect" in this sentence is not restricted or identified. Rather, we just learn additional information about the suspect: apparently, he owns a red car. Appositives Restrictive clauses are dependent clauses that begin with relative pronouns (who, whom, that, whoever, whomever, whichever) and are not surrounded by commas. Appositives are punctuated in a similar manner to parenthetical phrases or clauses. However, an appositive serves specifically as a noun or pronoun – often with modifiers. Appositives are placed beside another noun or pronoun in order to explain or identify it. Essentially, appositives serve to rename or restate another noun in the sentence. The elephant that trampled the village was drunk on fermented fruit. Example: The law teacher, a grammar enthusiast, emphasized the need to learn sentence structure and the parts of speech. Punctuating Restrictive versus Non-restrictive Clauses Non-restrictive clauses are dependent clauses that begin with relative pronouns (who, whom, which, whoever, whomever, whichever) and are surrounded by commas. Andy, who always admired John Lennon, was very sad to hear he was killed. Punctuation: If the sentence would be clear and complete without the appositive, then commas are necessary. In these cases, we would place one comma before and one comma after the appositive. In some cases, however, the noun being explained would be too general to be understood without the appositive. If the appositive is essential to the meaning of the sentence, then we do not place commas around the appositive. Example: The popular English prime minister Winston Churchill was well known for his eloquent and inspirational speeches. 4 Differentiating Sentence Types Simple: A simple sentence contains one independent clause. Example: We have only one week to study for the test. Compound: A compound sentence contains more than one independent clause. Example: We were frightened, but the mandatory English proficiency test was not nearly as hard as we imagined. Complex: A complex sentence contains one independent clause and at least one dependent clause. Example: Although he is a law teacher, Mr. Lightstone insists on teaching grammar. Compound-complex: A compound-complex sentence contains more than one independent clause and at least one dependent clause. Differentiating Sentence Types Hints on differentiating between sentence types: i) Focus on spotting subordinating conjunctions. They tell you right away whether a sentence is complex or not. They can, however, be hidden within the middle of a sentence. For example: “I didn't to go to work today because I was feeling sick.” There are actually two clauses within this sentence: "I didn't to go to work today" and "because I was feeling sick." Thus, this is a complex sentence. It would be much easier to spot if the subordinating clause came before the main clause. For example: “Because I was feeling sick, I didn't to go to work today.” ii) Remember that the smallest sentence possible consists of a noun and a verb. For example, “Jill fell,” “I ran,” “She hid,” etc. Why do I mention this? I point this out because we must always be aware that just two little words can at times produce a main clause within a larger compound or a compound-complex sentence. Example: If he is the nominee for the Democratic Party, Barack Obama will run against John McCain, but it won't be an easy contest to win. 5
