One of the reasons why grammar matters is because it is a vital part of communication. Good grammar allows you to communicate your thoughts and ideas clearly, and enables you to understand others when they communicate with you. poor grammar, on the other hand, can make it difficult to understand what someone is saying, and can even change the meaning of what they're trying to say.
In addition to being a vital part of communication, grammar also helps you to create a good impression of yourself. Using proper grammar shows that you are knowledgeable and well-educated, and can make a positive impression on potential employers, clients, or customers. Poor grammar, on the other hand, can give the impression that you are lazy, uneducated, and careless, which is likely to result in lost opportunities.
