Introduction to Commas
Welcome! In this chapter, we are going to look at one of the most useful tools in your punctuation toolkit: the comma. Commas might be small, but they have a big job. They act like little signposts or breathing marks, helping your reader know when to take a tiny pause and how to group ideas together. We will focus on three specific ways to use them: in lists, after fronted adverbials, and to clarify meaning.
1. Commas in Lists
When you have a list of three or more things in a sentence, you need to use commas to keep them separate. If we didn't use them, the words would all jumble together, and it would be very hard to read!
The Golden Rule for Lists
Put a comma after every item in your list, except for the very last one. Instead of a comma before the final item, we usually use the word and or or.
Example: For my birthday, I would like a bike, a helmet, a bell and some new lights.
Notice how there is a comma after bike and helmet, but we use and before some new lights.
Common Mistake to Avoid
Don't put a comma after the very last item in the list before you finish the sentence.
Wrong: I need eggs, milk, and bread, for my cake.
Right: I need eggs, milk and bread for my cake.
Quick Tip: If you only have two items (like fish and chips), you don't need a comma at all!
2. Commas After Fronted Adverbials
Before we talk about the comma, let's remember what a fronted adverbial is. An adverbial is a word or phrase that tells us more about a verb (like when, where, or how something happened). When we move that phrase to the front of the sentence, it becomes a fronted adverbial.
Why use a comma here?
We use a comma after a fronted adverbial to separate it from the main part of the sentence. This helps the reader see the "setting" of the sentence before the main action starts.
Examples:
• Time (When): Early that morning, the birds began to sing.
• Place (Where): Under the old oak tree, the children hid from the rain.
• Manner (How): Slowly and carefully, the cat crept towards the mouse.
Don't worry if this seems tricky! Just try reading your sentence out loud. Usually, you will naturally take a tiny breath right after the fronted adverbial. That is exactly where your comma should go.
Key Takeaway
Whenever you start a sentence with a phrase telling us when, where, or how, follow it with a comma.
3. Commas to Clarify Meaning
Sometimes, leaving out a comma can completely change the meaning of a sentence! We use commas to clarify meaning (make it clear) and avoid ambiguity (avoid confusion).
The Difference a Comma Makes
Look at these two sentences and see how the comma changes the story:
Sentence A: After we finished eating the dog, was hungry.
Sentence B: After we finished eating, the dog was hungry.
In Sentence A, it sounds like we ate the dog! (Oh no!) In Sentence B, the comma tells us that the "eating" part is finished, and now we are talking about the dog. The comma keeps the ideas separate so the reader doesn't get confused.
Another Example:
The teacher said the student is a genius. (This means the teacher is speaking.)
The teacher, said the student, is a genius. (This means the student is saying the teacher is a genius!)
Did you know? Using commas correctly can help you move from "working towards" to "working at the expected standard" in your writing assessments!
Quick Review Quiz
Check if you have mastered these rules:
1. Lists: Do you have a comma between each item except the last one?
2. Fronted Adverbials: If you started with a 'when', 'where' or 'how' phrase, did you put a comma after it?
3. Clarity: If you read your sentence, is the meaning 100% clear, or could a comma help separate the ideas?
Summary: Commas help organize your thoughts. Use them for lists, after fronted adverbials, and whenever you need to make sure your reader doesn't get confused! For other types of punctuation like brackets or dashes, you can check the chapter on "Parenthesis".
