'Spray' refers to a fine mist of liquid particles dispersed into the air, typically produced by a device that forces liquid through a narrow nozzle. The character 喷 means 'to spurt' or 'to eject forcefully', while 雾 means 'mist' or 'fog'—together, they literally convey 'ejected mist'. This compound is commonly used for medical, household, and cosmetic products that deliver liquid in aerosolized form.

You’ll encounter 喷雾 most often in contexts like asthma inhalers (哮喘喷雾), insect repellent sprays (驱蚊喷雾), facial mists (保湿喷雾), or cleaning solutions (消毒喷雾). Unlike generic terms like 液体 (liquid) or 雾 (mist), 喷雾 specifically emphasizes the *delivery method*—the act of spraying—and usually implies a pressurized or pump-action container. It’s a neutral, widely understood term suitable for both formal and everyday speech.
