Here are some basic rules to keep in mind when using commas:
Use a comma to separate items in a list: This is like separating different items in your shopping cart. For example, “I need to buy apples, bananas, and cheese” – the commas help to keep the items separate so you don’t end up with apple-banana-cheese salad.
Use a comma before coordinating conjunction: This is like using a stop sign to separate two different thoughts. For example, “I love pizza, but I don’t love anchovies” – the comma helps to separate the two independent clauses and make the meaning clear.
Use a comma to set off nonessential information: This is like putting a hat on something to make it stand out. For example, “My friend, who is a great cook, made us dinner” – the commas help to set off the information about your friend being a great cook.
Do not use a comma to separate a subject and its verb: This is like not putting a traffic light in the middle of an intersection. For example, “My cat sleeps on my bed” – the subject “my cat” and the verb “sleeps” should not be separated by a comma.
Here are the most common coordinating conjunctions:
adds information, connects ideas. Example: “I like pizza and ice cream.”
shows a contrast, introduces an unexpected idea. Example: “I love dogs, but I’m allergic to them.”
presents a choice between two or more options. Example: “Do you want to watch a movie or play a game?”
shows a contrast, introduces a surprising idea. Example: “I studied really hard, yet I still failed the test.”
An Oxford comma (also called a serial comma) is a comma used before the conjunction “and” in a list of three or more items. For example, “I bought apples, oranges, and bananas.” Some style guides recommend using the Oxford comma, while others do not. It ultimately depends on your personal preference and the style guide you are following.
No, a comma should not be used to join two independent clauses. This is known as a comma splice and is considered a grammatical error. Instead, you should use a conjunction (such as “and,” “but,” or “or”) or a semicolon to connect the two independent clauses.
A comma should be used before “which” in a sentence when the clause that follows is nonrestrictive (meaning it provides additional, nonessential information). For example, “The book, which was written by my favorite author, is on the shelf.” A comma should not be used before “that” in a sentence, as “that” is used for restrictive clauses (meaning the information is essential to the meaning of the sentence).
Yes, the placement of a comma can change the meaning of a sentence. For example, “Let’s eat, Grandma!” is very different from “Let’s eat Grandma!” The first sentence is a friendly invitation to eat with Grandma, while the second sentence is a disturbing suggestion to eat Grandma herself. It is important to use commas correctly to avoid confusion and convey the intended meaning of your message.
