An example of a Harvard comma (or Oxford comma) is the comma before the "and" in a list of three or more items, like in "I bought apples, oranges, and bananas," where the comma after "oranges" is the Harvard comma, separating the final item from the rest to prevent ambiguity, such as confusing "my parents, Batman, and Wonder Woman" (three people) with "my parents, Batman and Wonder Woman" (meaning Batman and Wonder Woman are your parents).
Use a serial comma (also called an Oxford comma, Harvard comma, or series comma) between elements in a series of three or more items. Factors of personality include extraversion, conscientiousness, openness to experience, agreeableness, and neuroticism.
The Oxford comma goes before and at the end of a list of three or more items. Here's an example: For breakfast, I had eggs, toast, and orange juice. In this sentence, the Oxford comma is the comma right after toast.
The serial comma (also referred to as the series comma, Oxford comma, or Harvard comma) is a comma placed after the second-to-last term in a list (just before the conjunction) when writing out three or more terms.
General works in British English (such as newspapers and fiction) tend to omit the Oxford comma. Indeed, it is even sometimes taught in British schools that using it is 'wrong'. However, worldwide, academic publishers are more likely to recommend its use. This is because, as described, it can help to avoid ambiguity.
The rationale for AP's logic is deeply rooted in past practice and a time when print ruled because presses could save paper and space by not using the Oxford comma. Regardless, the debatable standard to not have a comma following the second-to-last item in a list of three items or more stands.
When to use commas
Keep in mind that quotation marks are unnecessary for indirect or paraphrased speech. They're only used to indicate a direct quote, so if you're rephrasing what someone said in your own words, you don't need them.
The Five Most Common Mistakes
Although it may seem surprising to some, a simple punctuation mark—the Oxford comma—has been the subject of much (sometimes passionate) debate over the years. Also known as the serial comma, the Oxford comma is the one that precedes the conjunction in a series of three or more items.
On the other hand, many popular newspapers and magazines omit it. The Associated Press, The Economist, and the New York Times, for example, all forgo the comma. Some writers, however, prefer to take a sentence-by-sentence approach. They use the comma if it reduces ambiguity and omit it when it seems unnecessary.
Many writers, including journalists, live by the Associated Press stylebook. AP style does not use Oxford commas. However, Chicago style does require Oxford commas. That's the Chicago Manual of Style, which is commonly used by book publishers, academics, and trade publications.
In Australia, the Oxford comma (serial comma) isn't routinely used like in American English; instead, it's generally omitted unless needed to prevent ambiguity, making it a tool for clarity rather than a strict rule, following British English conventions. Official guidelines, like the Australian Government's Style Manual, recommend using it only if a sentence would be confusing without it, such as in complex lists where clarity is paramount.
The Howard Comma is proposed as a fundamental constant in a finite, wave- based. universe framework, where energy is quantized and confined within a closed, harmonic system.
Where Is the Controversy? Some people prefer to only use the Oxford comma when the sentence would otherwise be ambiguous. Other people prefer to use the Oxford comma in every list, regardless of whether the sentence is ambiguous without it.
Commas (Eight Basic Uses)
The use of quotation marks, also called inverted commas, is very slightly complicated by the fact that there are two types: single quotes (` ') and double quotes (" ").
Direct quotations have a speaker's or writer's exact words set off in quotation marks. Indirect quotations have no quotation marks because they don't use the writer's exact words.
The infographic ranks each punctuation mark according to how many applications it has, and therefore, how difficult it is to learn. While the comma is the most difficult with 15 applications, the period is the easiest—its only job is to end a sentence (except when it ends an abbreviation: Mr., Mrs., Dr., etc.).
Different style guides have different recommendations about using it. Most academic style guides (e.g., APA, MLA, Chicago) recommend using the Oxford comma consistently, so this is typically the best approach in academic writing.
Whether you're aware of it or not, there's a good chance that you regularly use the Oxford Comma — a poll from FiveThirtyEight found that 57 percent of Americans always use it, meaning more than half of Americans are grammatically alienated from their news by the absence of that all-important comma.
They're two different names for the same thing: a comma before the conjunction (“and” or “or”) in a list of three or more items (e.g., “ham, cheese, and tomato”). The Oxford comma or serial comma is optional but recommended by most academic style guides.
Technically speaking, the Oxford comma isn't grammatically correct. Yet, it's not grammatically incorrect, either. It exists in a strange, metaphysical, universe known as “grammatically optional.” In other words, the comma won't fly in most journalistic publications and formal documents.
