慢慢 (màn màn) is an adverb meaning 'slowly' or 'gradually', emphasizing a gentle, unhurried pace or a process that unfolds over time. Though both characters mean 'slow' individually, together they form a reduplicated adverb that softens the tone and conveys patience, care, or natural progression — not just physical slowness but also emotional or developmental change.

This word is commonly used in daily routines, instructions, advice, and descriptions of growth or healing. It often appears before verbs (e.g., 慢慢走, 慢慢吃) or in predicate positions (e.g., 他慢慢好了). Unlike single-character adverbs, the reduplication adds warmth and encouragement, making it frequent in parenting, teaching, and wellness contexts — for instance, urging someone to take their time learning or recovering.
