倾斜 (qīngxié) is a verb meaning 'to tilt, to lean, to slant' — it describes an object or surface that is not level or upright, or an attitude that leans in a direction. It is more formal and often used for physical inclines (e.g., a floor, a building) than 斜 (xié), which is a common adjective for 'slanted' in everyday speech. Unlike 偏 (piān), which can imply deviation or bias, 倾斜 focuses on the physical or metaphorical angle itself.
