Mistakes DupliChecker’s Punctuation Checker Can Correct

Duplichecker’s punctuation checker won’t leave any punctuation mistakes undetected in your text. The common punctuation mistakes you can correct with this tool include the following:



A comma is widely used in writing, representing a small break between different parts of a sentence. It also works as a separator when listing down items in a sentence. However, it’s commonly misused in writing, such as placing it before that in a clause, using it before a verb, etc. Whether you have mistakenly used a comma at the wrong place or missed using it in a sentence, the comma checker will catch the mistake and help you resolve it.


Colon and Semicolon

People often need clarification on the usage of colon and semicolon. Most commonly, people need to learn to use them in place of one another. In writing, a semicolon is used between two closely related sentences. On the other hand, a colon is used to introduce a list or define the meaning of a previous sentence or clause. Being a non-native writer, the usage of these two punctuation marks may need to be clarified for you. But there is no need to worry, as this tool also works as a semicolon checker that will help you detect and correct punctuation mistakes smartly.



An apostrophe is used to show the possession of someone or something in a sentence. This punctuation mark is often confused with contractions, i.e., shortening and combining two words; it also involves a mark similar to an apostrophe, which leads writers to face confusion. If you also need clarification with the usage of apostrophes in your writing, this punctuation checker will thoroughly check your content and let you know if any mistake needs to be corrected.


Dashes & Hyphens

The dashes and hyphens are also confused because of their similar appearance. However, they serve different purposes in writing. When you are required to join two or more words, a hyphen must be used. On the other hand, if you need to indicate a range or pause in a sentence, then you must use a dash. The online punctuation corrector is capable of detecting such minor mistakes in your text. So, you can take its assistance to make your writing flawless.
