What is a contronym?
Also called antagonyms, autoantonyms or Janus words, contronyms are words with two definitions that contradict – or are the reverse of – each other. Put another way, “a contronym is a word with a homonym (another word with the same spelling but different meaning) that is also an antonym (a word with the opposite meaning),” according to Grammarly.
Most people would automatically define the word ‘strike’ as ‘to hit or deliver a blow.’ But in baseball, it can also mean ‘to miss while trying to hit.’
If you ‘seed the lawn,’ you are adding seeds to the grass. But ‘seeding a watermelon’ means that you are removing the seeds, instead.
