Hello B1 Learners! 👋
Commas (,) are small but very important punctuation marks. Using them correctly helps make your writing clear, easy to read, and sound natural.
Today, we will review and learn more about using commas accurately in three common situations.
In this lesson, you will learn to use commas:
- In lists of three or more items.
- Before conjunctions (like "and", "but", "so") that join two complete sentences.
- After introductory words, phrases, or clauses.
Rule 1: Commas in Lists
When you list three or more items, use a comma to separate each item. It's also good practice to use a comma before "and" with the last item (this is called the Oxford or serial comma).
Structure: item 1, item 2, and item 3.
Examples:
- I need to buy milk, bread, and eggs.
- Her favorite colors are red, blue, yellow, and green.
- We visited Paris, Rome, and Barcelona on our trip.
Remember: If there are only two items, just use "and" (no comma). Example: I like tea and coffee.
Practice: Commas in Lists
Rewrite the sentence, adding commas where needed.
Rule 2: Commas Before Conjunctions in Compound Sentences
A compound sentence has two or more independent clauses (parts that could be a sentence on their own) joined by a coordinating conjunction.
Common coordinating conjunctions are: for, and, nor, but, or, yet, so (you can remember them with FANBOYS).
Rule: Use a comma , before the conjunction when it joins two independent clauses.
Examples:
- I wanted to go to the beach, but it started to rain.
- She studied very hard, so she passed the exam easily.
- We can go to the cinema, or we can stay home and watch a movie.
- He likes playing football, and he is very good at it.
Note: If you are joining two very short and closely related independent clauses with "and", the comma is sometimes optional, but it's usually safer to include it.
Practice: Commas with Conjunctions
Choose the sentence that is punctuated correctly, or rewrite the sentence adding a comma if needed.
Rule 3: Commas After Introductory Elements
When a sentence begins with an introductory word, phrase, or clause, use a comma , to separate it from the main part of the sentence (the independent clause).
Examples:
- Introductory Word: However, he decided to stay.
- Introductory Phrase (Prepositional): In the morning, I usually drink coffee.
- Introductory Phrase (Participial): Running quickly, she caught the bus.
- Introductory Clause (Dependent): When I finish this work, I will call you.
- Although it was raining, they went for a walk.
If the introductory element is very short (e.g., "Today," "Now,"), the comma is sometimes optional but often still helpful.
Practice: Commas After Introductory Elements
Rewrite the sentence, adding a comma in the correct place after the introductory element.
Mixed Comma Practice
Let's practice all three rules! Rewrite each sentence, adding commas where they are needed. Some sentences might need more than one comma, or none at all!
✨ Tips for Using Commas Accurately ✨
- Read Aloud: Often, a comma represents a natural pause in a sentence. If you pause when reading, you might need a comma. (But don't rely only on this!)
- Check for Lists: If you see three or more items being listed, you'll likely need commas.
- Look for Joining Words (Conjunctions): If "and, but, so, or, for, nor, yet" are joining two full sentences, put a comma before them.
- Identify Sentence Starters: If a word, phrase, or clause starts the sentence before the main idea, it probably needs a comma after it.
- When in Doubt, Simplify: If a sentence is very long and confusing with commas, try breaking it into shorter sentences.
- Review Examples: Look at well-written English to see how commas are used.
