Synonym discussion
Sense: noun/1
Fog, mist, haze, and smog all describe reduced visibility in the air, but they differ in cause and density. Fog is the thickest — visibility below 1 km — and consists entirely of water droplets near the ground. Mist is thinner than fog, with visibility between 1 and 2 km, and feels lighter and cooler; it often appears in the morning and clears as the sun warms the ground. Haze is caused by dust, smoke, or dry particles rather than water vapour, giving the air a gray or brown tint; it tends to persist for longer periods. Smog is a blend of fog and pollutants, common in densely populated industrial cities. For example: 'A thick fog delayed flights at the airport.' 'The morning mist lifted as the sun came out.' 'A haze of smoke hung over the stadium after the fireworks.' 'The government restricted traffic to reduce smog levels.'

Etymology
Mist comes from Old English 'mist', meaning darkness or mist. It traces back to Proto-Germanic '*mihstaz' and further to the Proto-Indo-European root '*meigh-', meaning to blink or to be foggy. Related words appear across the Indo-European language family: ancient Greek 'omíkhlē' (fog, mist), Sanskrit 'megha' (cloud), Old Church Slavonic 'mĭgla' (mist), and Lithuanian 'miglà' (fog).
