Using commas correctly is vital for proper punctuation and grammar.

You want your writing to be clear and engaging. Using commas correctly can help you do that.

You can quickly fix this issue by using a comma to lengthen the sentence while keeping your grammar in check.
If you are not confident in your writing yet, use a punctuation checker to help you.
Here is an example of using a comma to connect independent sentences.
She ran very quickly to catch the bus, but then she realized she forgot her phone.

Writing without commas can become a confusing read.
Adding commas in the right place can eliminate this problem.

In writing, you insert a comma after a word or phrase when it is grammatically correct punctuation.
The structure and the meaning of a sentence can depend on the usage of commas.
Let’s look at a very old, but useful classic example of how to eliminate confusion in your writing.

For my birthday, I invited Jen, Ben, and Sam to my party.
The message would still be the same without the last comma,
But in this example, there is a problem.
For dinner, we had pork stew, sweet potatoes, chili beans and ice cream.
For dinner, we had pork stew, sweet potatoes, chili beans, and ice cream.
Without the past comma, it reads as if the chili beans were served for dessert with the ice cream.
To be on the safe side, I would always add the last serial comma.

Most introductory adverbs need a comma before the main clause. Here’s a quick example.
Finally, I was able to go to the farm.
Suddenly, there was a raccoon on top of our roof.
However, I believed that he was speaking the truth.
The same rule applies to introductory adverbial clauses.
In the end, we decided to go to France.
In addition to that, we also booked a wine tour.
If you use an adverb or adverbial phrase to start a sentence, always use a comma after it.
When you are writing an address, there are usually many elements that make up that address.
You have the street name or building name, the suburb, and the name of the city you have to take into consideration.
If you are writing a letter, then the elements are separated by a line, but when you are writing it out in one line, you need to use commas to divide the information.
By using it correctly, you can easily eliminate any confusion by separating each element of the address.
Oxford Building Block 5 Tornado Street Birmingham 5000
Oxford Building, Block 5, Tornado Street, Birmingham, 5000
Each element stands alone, and the information is clear to the reader.
Just as with the address, writing out a full date needs to include commas in the right places.
There is the day of the week, the month, and the year you have to separate.
If you are only using the month and the year, it is acceptable to exclude any commas.
Monday September 12 2017 is going to include so much fun.
Monday, September 12, 2017, is going to include so much fun.
Commas make your writing precise and clear.
By separating these elements, you are being specific about the essential information in a sentence.
There are lots of comma rules, and some of them can be a little confusing.
But basic comma usage is essential in our everyday writing, as well as our professional writing.
