Cách sử dụng
The expression "have it in for somebody" means to have a strong dislike or ill will towards someone and to act in a negative or malicious way towards that person. It is usually used in a context where someone is being treated unfairly or is being targeted for no apparent reason. For instance, imagine someone who is consistently being blamed for things they didn't do or being given a hard time by a group of people. In this case, you could say "it seems like those people have it in for him/her." Essentially, this expression means that the person in question is experiencing hostility from others, but for no good reason.
