A combination of snow and rain. It's like slushy water(hydrogen oxide) falling out of the clouds in the sky. Not cold enough for snow but not warm enough for rain. The snain is in the soquid phase. Between a solid and a liquid. When the snain is falling out of the sky, it's snaining! H2O(l) ⇆ H2O(s) is basically liquid water and solid water at the same time, or H2O(sqd) which is soquid water, or soquid (sqd).
Wear your gloves and scarf and rain coat, it's snaining outside. Look at all that snain!
