Punctuation is the use of marks like commas, periods, question marks, and exclamation marks in a sentence to help it make sense and sound right. It's important to use punctuation in your writing and speaking so that people can understand you better. For example, if you don't use any punctuation, your sentence might be hard to read or comprehend. Punctuation can also change the meaning of a sentence or add emphasis to certain words. So, it's a good idea to practice using punctuation when you write or speak English.
