True Confession Time:
I have always loved the Amelia Bedelia stories. That is not what I need to confess, though. Everyone who loves words should love those books.
What I have to confess is I didn’t know that words that mean the opposite of each other are called contronyms.
Dust is a contronym.
So are
buckle
cleave
overlook
peruse
ravel
rent
sanction
screen
For when I am teaching linguistics or my ESL bridge class.
