| Prompt: | As you have noticed in the prior two exercises, some adjective clauses are marked off from the sentence with commas while other adjective clauses are not. Writers should mark off an adjective clause with commas if the adjective clause is just added information and is not really needed in the sentence. |
| Example: | Consider the following: 1) "Students who are receiving 'F' grades shall fail." The underlined adjective clause is not marked off with commas because the sentence would not make sense without it. The clause tells us which students "shall fail." 2) "Students at our school, which is the best school, are going to graduate." The underlined adjective clause is marked off with commas because the clause is just added information and is not necessary to the meaning of the sentence. Thus the independent clause, "Students at our school ... are going to graduate," has full meaning without the clause. |
