靠近 (kào jìn) is a separable verb meaning 'to approach' or 'to get close to'—physically, spatially, or sometimes metaphorically. The first character 靠 means 'to lean on' or 'to rely on', suggesting contact or proximity; the second character 近 means 'near' or 'close', reinforcing the idea of reduced distance. Together, they form a compound verb emphasizing movement toward something until nearness is achieved. It’s commonly used in everyday speech and writing when describing movement in space—such as approaching a building, person, or landmark—and often appears with directional complements (e.g., 靠近了, 靠近我) or time phrases (e.g., 越来越靠近).

This verb is neutral in register and appropriate in both spoken and written contexts. It typically takes a noun phrase as its object (e.g., 靠近车站), and unlike some verbs, it does not require aspect particles like 了 or 过 to be grammatical—but adding them clarifies completion or experience. While it can occasionally appear in abstract contexts (e.g., 靠近真相), its primary use remains concrete and spatial.
