The Serial Comma:  Commas with a List of Objects

What is a serial comma?

To Use a Comma or Not? This is a question that every writer faces.

When you have a list of three or more objects in one sentence,  the American standard is to place a comma before the conjunction.  Such a comma is called "a serial comma". 

  • Manta City has bushes, flowers, and fruit trees such as mango, banana, papaya, watermelon, and apple.

Always? Are there exceptions to this?

As a writer, you can choose to omit the serial comma if leaving it in creates confusion as to the meaning of what you're writing.

Be consistent.

  • The skin is dark, the lips are plump, the hair is black and curly, the forehead is tall, and the face is round. Juan has kind, brown eyes with a concerned look. He seems intelligent, noble, curious, and proud.

If you are writing for school or writing a resume or employment cover letter, be conservative and put the comma in.
