LV4 Commas.ppt Using Commas Correctly Using commas correctly is an important skill in writing clear sentences. This presentation explains nine common uses of the comma. Each explanation is followed by one or more examples. Using Commas Correctly (PPT) has been prepared for IELI Level 4 Writing students by Carol Ogden. It is available at
1. Items in a series* A.Willis Library has a reference desk and coffee shop on the first floor. B.Willis Library has a reference desk, a computer lab, and coffee shop on the first floor. Why are commas used in sentence B, but not sentence A? (B.) When there are three or more items in a series, use a comma between each item, including the last two. Follow this pattern: 1, 2, and 3. * “Series” refers to a list of three or more items. The items must be grammatically equal structures (e.g., noun, noun, and noun).
2. Independent clauses The Science Library has cookbooks, and Willis Library has current periodicals. Pattern: S +V, and S + V. for and nor but or yet so Connect independent clauses with FANBOYS:
3. Dependent and independent clauses 1.After the librarian demonstrated Boolean logic, she searched the database for articles. Note the position of the dependent clause: Dependent clause, independent clause. (comma) 2. The librarian searched the database for articles after she demonstrated Boolean logic. Independent clause dependent clause. (no comma)
4. Introductory phrases: short A.In 1977, IELI began to offer English classes to international students. B.Tomorrow morning I have a doctor’s appointment. (A.) In 1977 is an introductory phrase. Use a comma to separate the introductory phrase from the main clause. Why is no comma used in sentence B? (B.) Sometimes short introductory phrases (1-3 words) do not need commas. Why is a comma used in sentence A?
Introductory phrases: long A. In order to pass, a student must have at least a 70 final average. (A.) Use commas after long introductory phrases (4 or more words) Why is a comma used in sentence A?
5. Parenthetical* information The president of the university, Dr. Pohl, will be speaking in the Student Union at 3:00 p.m. today. Use commas because it is clear from the context that there is only one president of the university. His name is “extra information.” * “Parenthetical” means added or extra information
6. Coordinate Adjectives A.The short old man is a judge. B.The young, distinguished-looking man is the lawyer. Why is a comma used in sentence B, but not in sentence A? (A.) When adjectives appear in order, do not use a comma. (B.) When adjectives do not appear in order, use a comma. General order for adjectives: number + quality + size + age + color + origin + content
7. Quoted Speech “Be sure to visit the rare book collection on the third floor,” said the librarian. This is an example of a quoted sentence followed by the reporting verb and speaker. A comma is used instead of a period at the end of the quotation.
Quoted speech (cont’d) “The library,” said the librarian, “has a rare book collection on the third floor.” This is an example of a quoted sentence in which the reporting verb and speaker are placed in the middle of a sentence. Commas are used after the first part of the sentence and after the reporting verb and speaker. Note: has is lower case. Do not capitalize the word in the second part of the quotation. A period is used at the end of the quotation.
Quoted speech (cont’d.) “The library has a rare book collection on the third floor,” said the librarian. “Be sure to see the famous miniature apple- shaped book.” This is an example of two quoted sentences. The first sentence is followed by the reporting verb and speaker. A period is used after the speaker because the sentence is complete. The second sentence begins with open quotations and a capital letter. It ends with a period and closed quotations.
8. City and State A.IELI is located in Denton, Texas. B.Denton, Texas, is a small town. (A.)The city and state are at the end of the sentence. Use a comma between the city and the state. Why is a comma used in sentence B? (B.) The city and state are at the beginning (or middle) of the sentence. The state is parenthetical information. Therefore, commas are used before and after the state. Why is a comma used in sentence A?
9. Month, Day, and Year A.The first day of class was March 20, B.The first day of class was March 20. C.The first day of class was March (A.) With month, day, and year, use a comma before the year. (B.) With month and day, do not use a comma. (C.) With month and year, do not use a comma. Why is a comma used in sentence A, but not in B or C?
