In Defence of the Serial Comma

October 26, 2012

So Much Controversy Over a Tiny Punctuation Mark!

Also known as the series comma, the Oxford comma, and the Harvard comma, the serial comma has been cause for debate for many years. When I became the editor for ESL Library, I was thrilled to learn that their house style included the serial comma, because I prefer to use it myself. I’ve worked for other clients who’ve shunned its use, and it’s been hard to remember to leave it out. Even the style guides can’t seem to agree. The Chicago Manual of Style recommends its use, but the AP Stylebook does not. What do you do? Let’s have a look at some of the reasons to love the serial comma, and some of the reasons to dump it.

To Use

The first reason that comes to mind is clarity. Sometimes a serial comma is necessary to make the meaning of the sentence clear. One famous example that made the rounds on the internet was the sentence “We invited the strippers, JFK, and Stalin.” In this case, the meaning is clear—both JFK and Stalin were invited, as well as two or more strippers. Good times! However, if you don’t use the serial comma, as in “We invited the strippers, JFK and Stalin” you could assume that JFK and Stalin were the strippers. No thanks! Another reason for the serial comma is that its use reflects how we speak. In essence, commas are representations of pauses we make when we speak. To me, not using the serial comma means we shouldn’t pause at that part of the sentence when we speak. For example, think of the following sentence: I like apples, oranges, and pears. Which sounds better:

  • I like apples, oranges, and pears. = I-like-apples (pause) oranges (pause) and-pears.

  • I like apples, oranges and pears. = I-like-apples (pause) oranges-and-pears.

To me, using the serial comma (and therefore pausing) sounds better, both in my head and out loud. Maybe I should just stop talking to myself so much! ;)

Not to Use

I think the best argument not to use the serial comma is length. Your sentence is one character shorter without it, and since the meaning is generally the same with or without it, why bother making the sentence longer? I also think that not using it seems to be getting more common. Because of the AP and CP style guides, we don’t usually see the serial comma in newspapers or magazines. And with the advent of texting, making everything shorter is the popular choice! No matter what you decide to do, the important thing is to be consistent. Whether you have a strong opinion about it, or you were just taught to write a certain way, keep it consistent and you can't go wrong. So make a choice, stick to it(,) and have no regrets!

Hi Tanya,

Keep up the good work.

I am in China at the moment and have used many of your interesting lessons over the last year. Last night I recommended your site to a businessman friend, who is starting some part-time teaching this coming week.

Perhaps you should have a recommend a friend button? Anyway, I sent him the site link from my iPhone and this morning I was able to forward your latest newsletter to him, which is packed full of interesting new material.

Thanks for a great site and brilliant ideas!

Kind regards,

Whilst it can be confusing for people learning English, it is neccessary, as you say Tanya we pause in speaking so why not pause in written communications.
