Ah! Contronyms! Words that can mean a thing... and it's opposite (or nearly so).

Dust, cleave, overlook... many others. One of those enjoyable corners of the language.

For anyone else that was confused, apparently there is an alternate usage of the word 'Cleave' that means 'to adhere' (rather than 'to cut' or 'to separate').[0]

I hadn't heard of that one.

I almost feel like that specific usage should come with the 'archaic' tag, but it's reasonably common in slightly older novels, I think? Things like "He still cleaves to the imagined ideals of his forefathers".

It definitely tends to be used in a more philosophical sense than the very physical "cleave a block of wood in two", though.

"Biweekly" is a good one (half as often as weekly, but also twice as often as weekly).

The Amelia Bedelia series of children's books get tons of mileage from these types of words.

Weird quirks of language (English and others) usually have interesting histories too.
