The word 重新 is formed by combining two independent characters, each contributing its core meaning to create a new, composite idea. The first character, 重 (chóng), primarily conveys the concept of repetition, meaning "again" or "once more". It is joined with 新 (xīn), which means "new" or "fresh". Their combination does not merely add the meanings but fuses them into a single, integrated concept: to do something again, but with the specific quality of starting anew or making it fresh, thus forming the idea of "re-doing" or "starting over" with a renewed state or approach.
