Contronyms (also called autoantonyms and Janus words) are words with two meanings that contradict each other. Think of them as a combination of a homonym (words with similar spelling or pronunciation) and an antonym (words with opposite meaning).
A contronym is usually formed through two ways: different words with different origins being merged into one word, or one word acquiring different meanings over time.

The Confusion of Contronyms
English is a funny language. Even native English speakers regularly get befuddled by its many grammar rules and multiple word meanings. Here are a few sample sentences to illustrate how confusing contronyms can get:
- Before the police can bolt his cell, the thief bolted. He was bound for freedom until the police finally caught up and bound him again.
- After her daughter dusted her school project with glitter, the mom needed to dust both the table and the floor.
- A landlord rents a room to a tenant and a tenant rents a room from a landlord.
- The stars come out at night but it’s hard to see them until a few more lights are out.
- He buckled his backpack to his body but it was so heavy that his knees buckled for a moment.
If you only know one meaning of these words, the context of these sentences will not make sense. So it’s always good to be aware of the different (and sometimes contrasting) meanings of words.
Context Matters
So the next time a word trips you up, remember that even seemingly simple words can have multiple or contradictory significance.
Don’t always base a word’s meaning in its dictionary definition, but also in the context it was used.
