Commas before and in a Series
In American English usage, a comma should precede and with three or more items in a series.
Example: I would like to order a salad, a sandwich, and dessert.
Newspapers and magazines do not generally use this rule as print space is too valuable to use on what might be considered extraneous punctuation. However, print publications will use the final comma before and if it is needed to avoid confusion.
Example: Her $10 million estate was split among her husband, daughter, son, and nephew.
Omitting the comma after son would have led the reader to believe that the son and nephew had to split one-third of the estate (each receiving one-sixth) rather than understanding that each relative received one-fourth of the estate.

I get the comma part, but why isn’t it Environmental, Health, and Safety Policies?
January 30th, 2007 at 8:41 pm
Thank you! In grade-school English, we were taught that the comma before “and” is optional. Over the years, I’ve concluded that this was taught nationally, because the vast majority of people I have dealt with exclude the comma. My husband, who is from a different region, has even argued with me about it.
January 30th, 2007 at 10:21 pm
Katie, it could be “policies.”
T.J., while many people have been taught to exclude the comma before “and” in a series, putting a comma in helps clarify. That’s the whole point of punctuation!
January 31st, 2007 at 1:06 am
I was taught during my teen years that “and” can already be used as a separator instead of comma. Will it not be repeative if we use comma wiht and at the same time? But if that is the latest innovation now, then i will apply it. Many thanks
January 31st, 2007 at 1:10 am
Using a comma before “and” isn’t repetitive; it is helpful in letting your readers know that you mean a separate item on your list.
January 31st, 2007 at 1:22 am
I bought your blue book and read each of your messages with interest.Thank you!
Best regards, Robert E. Browne
January 31st, 2007 at 12:44 pm
Thank you. I didn’t know that. English pontuation is very diferent of brazilian
January 31st, 2007 at 3:45 pm
comma before “and” looks like a new thing in Grammar world. If it is, I would like to be more enlightened, because, for a list of words that is three and above, comma would be used to separate list of the worlds until you get to the last two when you will use “and” to separate them. Thanks
January 31st, 2007 at 5:46 pm
It is a common myth (and practice) to use “and” to replace the comma; however, The Chicago Manual of Style, along with every other authority (American), strongly recommends using the comma to avoid ambiguity.
January 31st, 2007 at 6:22 pm
When I was in school we were still taugh that the comma should be before the “and” in a series, but style manuals do differ in opinion. Most say it is not necessary but does help clairify things. I as a rule do not use it, and was taught that either way is correct but to pick one and be consistant in using it.
January 31st, 2007 at 6:28 pm
Hi, I thought the first one was correct, but that was because I thought the Health and Safety was one publication.
January 31st, 2007 at 6:58 pm
i agree with this rule. Leaving the comma out before “and” in a list of three or more items seems to join the last two items, at least to me. For example:
1) I have worked in the hardware, appliances, boys and girls departments.
2) I have worked in the hardware, appliances, boys, and girls departments.
Example 1 makes it unclear if there is a departement called “boys and girls” or if they are two separate departments. Example 2 makes it clear that they are separate.
February 1st, 2007 at 12:08 am
Maybe in the example given, a comma is necessary in order to separate
Health and Safety but normally, it is correct to write with or without a comma. The key is to be consistent.
February 1st, 2007 at 12:09 am
Dera, see my comment above about what the Chicago Manual of Style says. Thanks for writing.
February 1st, 2007 at 6:31 am
This is known as the Oxford comma. In U.K. English, it would be incorrect to use it while in U.S. English, it is mandatory.
February 1st, 2007 at 11:26 am
After all this year I always use there is no comma before “and”. I think, comma before “and” litle bit over writting. What I mean is, when we are not using comma before “and”, there is no confusion because “and” is explainning the changing of the words or object.
February 2nd, 2007 at 12:20 pm
Commenting on the reply by Phillip Dunn, I suggest the use of & instead of ‘and’ to clarify that two items make up one item of the list. For example:
I have worked in the hardware, appliances, and boys & girls departments.
I have been using this technique while writing user manuals.
February 2nd, 2007 at 3:08 pm
This is fine for manuals, perhaps, but not for formal writing.
February 2nd, 2007 at 4:47 pm
i am greatful to you for sending materials regularly. it is helping me a lot.
February 2nd, 2007 at 10:41 pm
This is a small discussion I have had with my English teacher in high school recently. She claimed that using a comma before “and” in a title is incorrect (in fact the title of the document was, “Explain, describe and narrate”). I have said that I will prove myself right, and the evidence in this blog is quite sufficient in my eyes.
Although, I do have a request. Please clarify whether the comma before “and” applies in ALL contexts or just body of a letter or such.
Thank you
February 4th, 2007 at 4:26 am
Jane, While Chicago insists on serial comma, AP specifically does NOT use it. I don’t think this is a cut-and-dry issue. I teach high school English, and the Elements of Writing series (very commonly used) specifies that either is correct.
February 4th, 2007 at 5:18 pm
Stephanie, perhaps this debate will never be resolved. I suggest using the comma before “and” in a series for clarity since there are many occasions when leaving it out causes confusion for readers.
Dmitry, I don’t know what other contexts you are referring to in your question. Please clarify.
February 6th, 2007 at 1:04 pm
Sorry to be a curmudgeon (well, not really) but I don’t agree with the use of the comma before the last “and.”
Many here report that this was taught in school, confirming to me that it is a recent affectation. I can tell you it wasn’t taught in any of the 6 different Catholic grade schools I attended as our family moved around in the 30s and 40s, nor was it taught in the Jesuit prep high school in any of the three languages that were required.
Having written professionally (as in “for pay) for hundreds of magazines, newspapers, websites, pamphlets, manuals and commercial publications, I have never had an editor insert that extra comma.
(BTW, did anyone here have a problem understanding that previous sentence because it lacks an extra comma?)
I do not recall, offhand, ever seeing it in the fiction or non-fiction of any published writers prior to recent times.
It remains a mystery for me as to how it got started and an even deeper one as to why it continues.
February 6th, 2007 at 8:30 pm
I disagree with our comma tip when it comes to listing things. In Associated Press style, you do not add a comma before AND. It might not be relevant to your audience, but I thought I would mention it.
February 6th, 2007 at 8:35 pm
Hasn’t that rule fluctuated? I remember the Comma in after the :”and” then for awhile, then it was out after the “and.”
I have a question re: the period after or before the second quotation mark. I can’t stand seeing “floating periods”! (or exclamation marks, for that matter) Ex: He was a “true, blue friend”.
February 7th, 2007 at 1:29 pm
I’ve always read, and taught my students, that the comma before and wasn’t necessary; actually, I believe it would be correct both ways—with or without the comma.
February 7th, 2007 at 9:37 pm
Dear Jane,
My four yr college degree was in English, and I was taught throughout grade school, junior high and high school that you do NOT need a comma before the word “and” as that is what the word “and” is for. However, if you are changing subject matter, then a comma would be warranted.
I am the Sr. Tech in our Publications Dept here in a large school district, and I receive masters with and without the comma before the word “and”. I think it’s 50-50 now, but mostly older teachers leave out the comma. I instruct my four children to NOT use the comma; it’s redundant.
Thanks for your informative and helpful weekly email newsletter,

If, for poetic reasons, one wanted to write “Athenians and Trojans and Spartans have long been…”, would you still insist on commas before each “and”?
February 26th, 2007 at 4:05 pm
Lance, I would not use commas to separate “Athenians and Trojans and Spartans have long been…”
Brian, how about sharing G.V. Carey’s response so that we know what he said?
Heather and everyone else who disagrees with using the comma before the last “and” in a series: I’m sticking with my recommendation to use the comma.
February 27th, 2007 at 4:55 am
Can I use a colon after using ‘For example’?
Example: The elements leading to the resulting disaster were many, for example: …….
February 27th, 2007 at 5:07 am
No, you can’t use a colon after “for example” in a sentence. Here are some possible ways you could handle the sentence:
The elements leading to the resulting disaster were many, for example, …
The elements leading to the resulting disaster were many; for example, …
The elements leading to the resulting disaster were many: [then don't use "for example"]
March 17th, 2007 at 9:16 pm
THANK YOU! This has always been confusing to me. I’m delighted to know the rule so I can finally punctuate accurately.
March 29th, 2007 at 12:29 pm
Philip Dunn has given explicit example of Girls’ and boys dept., and Girls’, and boys dept. It clarifies what Jane proposes.

“Always use a comma before and with three or more items in a series to avoid confusion.”
Except, of course, when it creates confusion.
to my parents, Brad, and Janet
to my parents, Brad and Janet
March 30th, 2007 at 8:00 pm
Good point!
April 20th, 2007 at 4:33 pm
Ref. last examples above.
” to my parents, Brad, and Janet”…meaning Brad and Janet other than the parents?
“to my parents, Brad and Janet”…meaning Brad and Janet are her parents.
Am I right?

Yes!

Putting a comma before an “and” isn’t proper English! But this is America… where we never teach anyone to do things properly. Instead, we “dumb” things down to make them easier for everyone. No wonder this country is going down the tubes.
June 5th, 2008 at 1:32 am
Who says that putting a comma before “and” isn’t proper? If this country is indeed “going down the tubes,” in my mind, the comma before “and” doesn’t rank with media and government attempts at “dumbing” us “down.”
June 9th, 2008 at 4:55 pm
I usually use the “comma before the and.”
But in some situations, is it better to not use the comma?
I work with advertising, marketing, and signage materials and notice that many professional pieces deliberately drop the comma before the and; it seems to be done by design.
Is it possible that the “comma before the and” is not desired or needed in certain situations, like advertising or signage?
June 9th, 2008 at 4:58 pm
If a customer doesn’t desire the comma before “and,” then leave it out, of course. However, I find that people are not often aware of this rule and are happy to have the comma added for them.
June 10th, 2008 at 10:25 pm
I am an editor, and I believe that using a comma after “and” is most beneficial for a variety of reasons. As a background, I grew up being taught in elementary school through high school you use a comma in a series. For my editing classes in college, we followed the Chicago Manual of Style. The latest edition of Chicago (which is one of the most often used style guides) recommends using the oxford or serial comma. The use of the comma is most helpful to delineating what constitutes a separate entity in a list and also serves to avoid ambiguity. The AP Stylebook, most often used for newspapers and other media, does recommend the comma be omitted before the “and.” I believe this is because AP style focuses more on brevity. Newspapers and the like often have limited space for publication. An extra comma adds extra space to the typesetting. However, I still recommend that for most purposes a comma be used before “and” in a series to avoid ambiguity. That is one of the chief purposes of punctuation and one of the chief rules of writing. Strive for clarity and avoid ambiguity.
June 10th, 2008 at 10:29 pm
Bravo! Ditto to all your thoughts, Tracie.
June 11th, 2008 at 5:21 pm
Thanks for the info.
I also think that the brevity idea (from AP Stylebook) may be applied to commercial advertising, graphic design, and marketing work for commas before and. It seems like a lot of comma exclusions take place in those situations, for space saving and also possibly aesthetical reasons (from what I’ve seen). Anyone else work in those fields?
July 17th, 2008 at 6:29 pm
NK, who defines proper English? I would think Oxford University is a fairly authoritarian source on the matter and they say to use the comma - despite the fact that its use is less standard in Britain and the US.
There are cases where the Oxford comma is ambiguous and cases where its omission is ambiguous.
Molly, a painter and a musician…. Is that one person or three?
My dog, Ruffles, and a cat…. Is ruffles my dog or are there three seperate animals?
Many style guides say to use the Oxford Comma. I would not call following these style guides incorrect or lazy.
Most newspaper authorities (AP, New York Times, etc.) request to not use the comma for space reasons. This is not a good reason to set a grammar precedent.
As for the Oxford comma being a new invention, that is just plain false. The debate about whether to use it or not has been around for a long, long time. I learned to use it in the ’80s and I was being taught be 80 year old teachers who wanted things to be done the way they did it as a child. From my understanding the sentiment on this issue has changed several times over the years.

My main reason for searching this site was to determine if the comma before the and is needed in a list of names. I create birth announcements and at the bottom we list the names of the members of the family such as Victor, Melissa, Kevin, Jenna, Olivia, Gabrielle and Hunter. I have always left out the “oxford” comma, but many of my customers ask me about this when they view their proof. Always the comment is “I think there should be a comma before “and”, but I am not sure” I have always told them the “and” replaces that comma (and thought it did in every instance), but after reading all of the above wisdom, I am going to amend my stance and say that it is used when the last two words in the series could be inadvertently joined in the reader’s mind by the word “and” instead of separated as intended. Great examples above. I was taught not to use it, I graduated high school in 1981 and college in 1986. My son is in 5th grade and is taught to use it in every instance. For names, I think it is unnecessary, and feels redundant, but for a list of objects or elements that could be joined - boys and girls, health and safety, the dog, and parent examples, (vs. the dog and parent) I think we have to use it if indeed each is a separate element. Conversely if the last two in the list are joined, my parents, Bart and Jean, then of course we’d leave it out. Thanks everybody!
May 6th, 2009 at 4:15 pm
Every school text I ever used said to use a comma before every item in a series of 3 or more. I have my college writing book right here, and it says to use the comma before and. The exception to the rule is in newspapers and magazine because they like to save space. The comma helps with clarity.
The car lot purchased some new cars. The cars are red, blue, green, black, and white.
If you write-
The cars are red, blue, green, black and white. This looks like the last car is a 2 tone car that is both black and white. This is confusing.
USE the comma!
