The Chinese word **合唱** is a compound word formed through semantic combination, where the first character **合** (hé) means "together" or "to combine," and the second character **唱** (chàng) means "to sing." When combined, the two morphemes create a new meaning that is the sum of its parts, literally "to sing together," which specifically refers to a **chorus** or **group singing** as a coordinated musical performance. This formation follows the common Chinese word-construction pattern of modifier (how) + action (what), resulting in a precise and intuitive term for the activity.
