Etymology

Origin of slush

1635–45; apparently cognate with Norwegian slusk slops, Swedish slask mud, slops

Explanation

Slush is messy melted snow, a mixture of ice and water. If you forget to wear your waterproof boots, you'll want to watch out for the slush as you walk through the city in February. Slush forms when snow melts slightly, leaving behind a substance that's similar to snow, but wetter. A sweet, icy drink is also a slush or a slushy, while a "slush pile" is a heap of manuscripts and letters that are sent, unsolicited, to a publisher. And a "slush fund" is either an extra, backup bank account, or a secret one full of illegally obtained money. One thing is for sure: slush is messy.
