安装 (ān zhuāng) is a verb meaning 'to install' — typically referring to setting up software, hardware, appliances, or equipment so it functions correctly. The character 安 (ān) means 'peace', 'safety', or 'to place securely', while 装 (zhuāng) means 'to equip', 'to fit', or 'to dress'. Together, they convey the idea of 'placing something in position for proper use', emphasizing both physical placement and functional readiness. It’s commonly used with computers, apps, home fixtures, air conditioners, and security systems.

This word is neutral in register and appears frequently in technical manuals, IT support conversations, DIY guides, and customer service contexts. It can be used transitively (e.g., 安装软件) or in passive constructions (e.g., 已经安装好了). Unlike some English uses of 'install', 安装 rarely applies to abstract concepts like ideas or policies — it almost always involves tangible or digital systems requiring setup.
