before的反义词英语怎么写？

"Before" refers to something that happens or exists earlier in time or in a certain sequence. On the other hand, "after" indicates an event or occurrence that takes place later or follows another event. It is the opposite of "before". For example, if I say, "I will have lunch before the meeting," it means that I will eat my lunch earlier in time compared to the meeting. However, if I say, "I will have lunch after the meeting," it means that the meeting will end before I have my lunch."
