‘剥落’ (bō luò) is a verb meaning 'to flake off' or 'to peel off', typically describing the gradual, often natural or weather-related detachment of outer layers—such as paint from a wall, bark from a tree, rust from metal, or dead skin from dry hands. The first character 剥 means 'to peel' or 'to strip', and the second character 落 means 'to fall' or 'to drop'; together, they vividly convey the action of something coming away in fragments or layers due to aging, exposure, or deterioration.

This word is commonly used in descriptive, observational, or slightly formal contexts—especially when discussing physical decay, restoration work, botany, or art conservation. It implies an incomplete, uneven, or partial detachment—not a clean, intentional removal like peeling fruit (which uses 剥皮). It’s often paired with nouns like 油漆 (paint), 树皮 (bark), 瓷器釉面 (glaze on porcelain), or 皮肤 (skin), and frequently appears in passive constructions or with degree adverbs like 已经, 逐渐, or 大片地.
