The word "大闹" is formed by combining the character "大", meaning "big" or "great", with the character "闹", meaning "to make noise" or "to cause a disturbance". Together, they create a compound verb where "大" intensifies "闹", resulting in a meaning that conveys creating a major commotion or making a big fuss, such as in "大闹天宫" (raising havoc in the Heavenly Palace). This formation directly uses the literal meanings of the individual characters to express an amplified action.
