Is it correct to say "I had a chat to my brother"? I normally use the word 'with' my brother.

We chat with other people. We don't chat to them.

Yes, you are correct. The more common and grammatically correct way to express the action of communicating with someone is by using the preposition "with." So, it would be more appropriate to say "I had a chat with my brother."

To determine the correct usage, it is helpful to understand the difference between "to" and "with" in this context. When we say "chat with someone," it implies direct communication and interaction between two or more people. On the other hand, using "to" suggests that you are directing your conversation or thoughts towards someone, but not necessarily engaging in a two-way conversation.

To improve your grammar skills and usage of prepositions, it is recommended to consult reliable grammar resources, such as grammar books, online grammar websites, or even grammar-focused language courses. These resources can provide you with detailed explanations and examples to help you understand when and how to use prepositions correctly in different contexts. Additionally, practicing and exposing yourself to more English conversations and texts will also help reinforce proper usage. Overall, it is essential to continually learn and reinforce language skills to improve your overall fluency and accuracy.
