The difference between extreme and extreme lies in semantics and usage occasions.
Both "extreme" and "extreme" mean reaching the extreme or the limit. However, extreme is more used to describe the quality, realm, level, etc. of things, emphasizing that it has reached the highest point, which is a high degree of performance; while extreme is more used to describe the degree, depth, and level of things. In terms of breadth and other aspects, the emphasis is on reaching the maximum extent, which is a quantitative expression. Therefore, extreme is more used in literature, art, philosophy and other fields, while extreme is more used in science, technology, business and other fields.
