The word 'against' is used to show that you are doing something in opposition or resistance to something else. For example, you can be against a decision, a belief or an action. It can also be used to describe a physical contact or collision with an object or person. For instance, if you hit a ball against a wall or lean against a wall, you are using the word 'against'. Additionally, it is often used to show a comparison, like "the new phone is better than the old phone".
