Here's a breakdown:
* Do: This verb typically refers to performing an action. For example: "Do your homework," "Do the dishes," "Do a dance."
* Have: This verb typically refers to possession or state of being. For example: "Have a car," "Have a headache," "Have a good time."
Where they seem opposite:
* In response to questions: If someone asks "Do you have a car?" you might answer "Yes, I do." Here, "do" is replacing "have" but refers to the same action (possession).
* In expressions: "Do your best" and "Have a good day" are both common phrases. While they express different desires, they can be seen as opposites because one encourages action and the other a state of being.
Key Takeaway: "Do" and "have" are not true opposites, but their meanings can overlap and create a sense of opposition in certain situations.
