Did you know?

Cleave is part of an exclusive lexical club whose members are known as [contronyms](https://www.merriam-webster.com/dictionary/contronym): words that have two meanings that contradict one another. In the case of cleave the two meanings belong to two etymologically distinct words. One [cleave](https://www.merriam-webster.com/dictionary/cleave#h1) means “to adhere firmly and closely or loyally and unwaveringly,” as in “a family that cleaves to tradition”; it comes from the Old English verb clifian, meaning “to adhere.” The [cleave](https://www.merriam-webster.com/dictionary/cleave#h2) with meanings relating to splitting and dividing comes from a different Old English word, clēofan, meaning “to split.” So although one might assume the two were once cleaved to one another only to become cloven over time, such is not the case!
