相差

相差 means 'difference' or 'gap' between two things. It often refers to a measurable or noticeable distinction, such as in age, size, quality, or time.

The character 相 (xiāng) means 'mutual' or 'each other,' and 差 (chà) means 'difference' or 'disparity.' Together, they form a term that emphasizes the contrast or gap between two entities.

相差 is commonly used in everyday conversations to describe differences in age, height, or performance. For example, people might say 他和我相差两岁 (He and I are two years apart in age). It is also used in more formal contexts, such as comparing data or results.
