Period Placement: 3 Easy Rules

When it comes to writing, one of the simplest yet most debated topics is the placement of periods. This seemingly insignificant punctuation mark can spark intense discussions among grammar enthusiasts and writers alike. So, let’s dive into three straightforward rules that will help clarify the confusion surrounding period placement.
The first rule is quite straightforward: Place the period at the end of a complete sentence. This rule might seem obvious, but it’s worth emphasizing because it forms the foundation of period usage. A sentence, as you may know, is a group of words that expresses a complete thought. So, when you have a subject and a verb that agree and convey a meaningful idea, you’ve got yourself a sentence. And at the end of that sentence, you place a period. Simple as that.
However, things can get a bit tricky when we consider the second rule: Periods belong inside quotation marks. This rule might seem counterintuitive to some, but it’s a fundamental principle of punctuation. When you’re directly quoting someone or something, the period goes inside the closing quotation mark. For example, consider the sentence, “I love the way the morning sun shines through the trees,” said the artist. Here, the period follows the quotation mark, even though it might seem like it’s interrupting the flow of the quote. This rule holds true for both single and double quotation marks, ensuring consistency in your writing.
The third rule is a bit more nuanced and pertains to abbreviations and acronyms. Generally, periods are used with abbreviations, such as Mr., Dr., or etc. However, with the rise of acronyms and text-speak, the use of periods has become a bit more flexible. For instance, when writing acronyms like NASA or ASAP, it’s not necessary to include periods. These acronyms have become widely recognized and are considered stand-alone words in their own right. On the other hand, when dealing with initialisms (abbreviations formed from the first letter of each word, like FBI or U.N.), periods are still often used, although some style guides advocate for omitting them for a cleaner, more modern look.
Now, a word of caution: while these rules provide a solid framework, language is ever-evolving, and style guides may differ in their recommendations. It’s always a good idea to refer to a trusted style guide, such as the Chicago Manual of Style or the Associated Press Stylebook, for more specific guidance. Additionally, keep in mind that writing is an art, and sometimes breaking the rules can lead to creative and effective communication.
In conclusion, the placement of periods might seem like a minor detail, but it plays a crucial role in conveying your message clearly and effectively. By following these three simple rules, you can ensure that your writing is not only grammatically correct but also polished and professional. Remember, attention to detail, even in the smallest aspects of writing, can make a significant impact on the overall quality of your work.
