CONTRANYMS
Sanction. Cleave. Oversight. Outstanding.
Each of these words is a contranym, which means that it has two meanings that are almost opposite. Sanction can mean to authorize, and also to penalize. Cleave can mean to cling to or remain faithful to, and also to split apart. Oversight can mean to supervise, and also to omit or err. Outstanding can mean excellent, and also not yet paid or submitted.
I believe that cleave is actually two different verbs that happen to be spelled the same in the infinitive and present tense. In the meaning “remain faithful,” the past tense is “cleaved”:
Through all adversity their hearts cleaved more strongly together.
In the meaning “split,” the past tense is “cleft”:
The cleft logs were further split into firewood.
