Common Mistakes in English Grammar

As English speakers, we often make mistakes in grammar without even realizing it. These mistakes can range from minor slip-ups to errors that completely change the meaning of a sentence. In this article, we will explore some of the most common grammar mistakes and how to avoid them.

dunno (don't know)

One common mistake in spoken English is using "dunno" instead of "don't know." While "dunno" is widely used in informal conversations and text messages, it is not considered proper English.


  • Incorrect: I dunno where he went.
  • Correct: I don't know where he went.

To avoid this mistake, it is important to remember to use the full phrase "don't know" in formal settings or when writing. Using proper grammar in your communication will help you sound more professional and ensure that your message is clear to the reader or listener.
