Identifying and Correcting Sentence Errors Fragments and Run-Ons Identifying and Correcting Sentence Errors  Les Hanson 2002

Introduction This presentation explains the following grammatical concepts: Clauses (dependent and independent) Sentences Fragments Run-Ons Coordinating Conjuntions Subordinating Conjunctions Conjunctive Adverbs Semicolons

Clauses A clause is a group of words with a subject and a verb You stink. Sally is talking. Most clauses have further information after the verb Subject Verb You smell like wormy compost. Sally is talking loudly to her friends.

Two Types of Clauses Independent clause (Main clause) Can stand alone as a sentence Can be joined to another clause Fred filled a cardboard tube with gunpowder. Dependent clause (Subordinate clause) Cannot stand alone as a sentence Must be joined to an independent clause Because he wanted to make his own firecrackers. A word that joins clauses is a conjunction

Joining Clauses A dependent clause can be joined to an independent clause to make a sentence. Fred filled a cardboard tube with gunpowder because he wanted to make his own firecrackers. …or… Because he wanted to make his own firecrackers, Fred filled a cardboard tube with gunpowder. When the sentence starts with the dependent clause, it must have a comma before the independent clause

Fragments Fragments look like sentences but are missing a subject or a verb, or they are put together incorrectly. Fragment Error Told everyone to get out of the way. No subject Disposable lighter in his hand. No verb Before he lit the fuse. A dependent clause by itself

Correcting Fragments Subjects or verbs can be added… Fragments can be joined together… Phrases and clauses can be moved around… With his disposable lighter in his hand, he told everyone to get out of the way. Then he lit the fuse. Pulling out his disposable lighter, Fred told everyone to get out of the way before he lit the fuse. He pulled out his disposable lighter. Fred told everyone to get out of the way, and then he lit the fuse.

Run-ons Run-ons (fused sentences) occur when clauses are joined incorrectly. Run-on The fuse burned too quickly before he could throw it the explosive blew up between his legs. He didn’t throw the firecracker, he placed it between his legs, he wanted to put the lighter away first. Comma splice

Four Ways to Correct Run-ons Join the clauses with a comma and a coordinating conjunction (FANBOYS) for, and, nor, but, or, yet, so He wanted to put the lighter away first, so Fred placed the firecracker between his legs, and he didn’t throw it right away. Join the clauses with a subordinating conjunction (AWUBIST) because, although, if, when, since, after… Because the fuse burned too quickly before he could throw it, the explosive blew up between his legs.

Four Ways to Correct Run-ons Make the clauses into separate sentences Fred fell down screaming when the smoke cleared we all expected to see a bloody mess. Fred fell down screaming. The smoke cleared. We all expected to see a bloody mess. Fred fell down screaming! We all expected to see a bloody mess when the smoke cleared.

Four Ways to Correct Run-ons Join two independent clauses with a semicolon (;)if they are closely related. You may include a conjunctive adverb along with the semicolon: however, for example, therefore, moreover, indeed Fred hadn’t taped the tube properly and most of the force was released out the ends of the tube the explosion did direct some pressure against his groin. Fred hadn’t taped the tube well, and most of the force was released out the ends of the tube; however, the explosion did direct some pressure against his groin. Notice how the sentence is punctuated
