For example: Jane drove to work. "Jane" is the subject; "drove" is the verb.
A sentence fragment is a group of words that does not make sense alone, because it lacks a subject and a predicate. A sentence fragment can result, because it contains a word or phrase that makes it a dependent clause (needing additional words to make sense).
For example: Because the one I have now does not work.
Possible revision: I need to purchase a new drill, because the one I have now does not work.
Compound sentences are necessary in order to avoid choppy writing by combing sentences with a comma followed by a conjunction. Conjunctions are words used to connect clauses or sentences to coordinate words in the same claus. Conjunction examples are: and, but, for, nor, or, so, yet.
For example: Katniss can survive in the forest, and she is a capable archer.
Complex sentences combine independent clauses with dependent clauses.
Dependent claus is introduced by a preposition, prepositional phrase, or adverbial phrase.
For example: When equipped with her bow and arrows, Katniss can survive in the forest.
Run-on sentences are two sentences incorrectly combined.
For example: I love chocolate mile I would drink it everyday if I could.
Comma splices are two sentences incorrectly combined using a comma.
Hint: A comma cannot serve as a connector between two sentences.
Comma Splice: The results of the study were inconclusive, therefore more testing must be done on the topic.
Correct revision: The results of the study were inconclusive; therefore, more testing must be done on the topic.
