Commas are widely used form of punctuation. While it’s true that a comma signals a reader to pause, there are many other reasons to use a comma. In this lesson, we will look at 5 common ways that commas should be used. One place you would use a comma is between a day and a year. In this example, place a comma between March 26 and 2020. Commas should also be placed between the day of the week and the date. The comma in this sentence would need to be placed between Friday and April 18th. A comma should also be placed between the name of a city and state. This example would require a comma to be placed between Austin and Texas. You should also use commas after an expression that begins a sentence. This sentence starts out with an introductory word, well, so you would need to place a comma right after well. Some other introductory words you may come across are yes, no, however, suddenly, and meanwhile. Commas should also be used to separate items that are listed in a series of 3 or more. Place a comma after each item except for the final item. For this example, commas need to be placed after the words sausage, pepperoni, and cheese.
