The word **缓缓** (huǎnhuǎn) is formed through the morphological process of **reduplication**, where the single character **缓** (huǎn), meaning "slow" or "delay," is duplicated to create a new adverb. This repetition intensifies and softens the meaning, shifting it from the simple adjective "slow" to the more descriptive and gradual adverbial sense of "slowly," "leisurely," or "gently." Reduplication in Chinese often conveys a continuous, unhurried, or deliberate manner, and in this case, it creates a poetic and slightly formal tone commonly used in both written and spoken language to describe a gentle, steady motion or action.
