Commas in English Grammar

Commas in English

Rule 1: Lists

• Use commas to separate items in a list
• Example: "I like eating oatmeal, berries, and cheese for breakfast"
• This rule applies to lists of nouns, adjectives, or adverbs

Rule 2: Coordinate Adjectives

• Use commas to separate coordinate adjectives (adjectives that describe the same thing and can be swapped in order)
• Example: "She is a fit, healthy woman"
• If you can swap the adjectives and the sentence still makes sense, use a comma
• Cumulative adjectives (adjectives that describe different things) do not need commas

Rule 3: Independent Clauses

• Use commas to separate two independent clauses (sentences that can stand alone)
• Example: "Success is their goal, yet happiness comes a close second"
• Use coordinating conjunctions (and, but, yet, for, nor) to connect the clauses

Rule 4: Introductory Clauses

• Use commas after introductory clauses (clauses that start with words like "while", "because", "although", etc.)
• Example: "While I was eating, my husband came home from work"
• If the introductory clause is at the end of the sentence, no comma is needed

Rule 5: Introductory Phrases

• Use commas after introductory phrases (phrases that introduce the sentence)
• Example: "To get a seat, you'd better come early"
• If the phrase has four or more words, use a comma

Rule 6: Non-Essential Information

• Use commas to separate non-essential information (information that adds value but can be omitted)
• Example: "Oranges, which are my favorite fruit, are the main ingredient in this recipe"
• If the information can be removed or rearranged without changing the sentence's meaning, use a comma

Rule 7: Introductory Words

• Use commas after introductory words (words like "no", "yes", "why", etc.)
• Example: "Why, I can't believe this!"
• Use commas to separate the introductory word from the rest of the sentence

Rule 8: Quotations

• Use commas to separate quotations from the rest of the sentence
• Example: "He said, 'I'll call you tomorrow'"

Rule 9: Dates

• Use commas to separate dates in the format "day, month, year"
• Example: "Thursday, September 12, 2013"
• If the date format is different, commas may not be needed

Rule 10: Addressing Someone

• Use commas to separate the person's name from the rest of the sentence
• Example: "Will you, Alice, come to my birthday party?"

Rule 11: Addresses

• Use commas to separate attributes in an address
• Example: "John Smith, 123 Palm Street, Miami, Florida 33004"

Rule 12: Additional Information

• Use commas to separate additional information (non-essential information that adds value)
• Example: "Alexander Pushkin, the Russian poet, is one of the world's most famous poets"

Rule 13: General Tips

• Use commas to clarify the meaning of the sentence
• Practice using commas to improve your writing and communication skills
