English is notoriously hard to learn, but contronyms may be trickiest words of all
What do you mean the same exact word can have two completely opposite meanings?

Contronyms prove that the English language is all about wordplay.
The English language has so many words and grammar rules that make it unique. Growing up taking English classes, kids are taught the basics like synonyms (words with the same or similar meaning), antonyms (words with opposite meanings), and idioms (a phrase or expression whose meaning cannot be deduced from the literal meaning of its words).
But there is another grammar term to describe words and their meaning that you might have missed during your school years: contronyms. As defined by Merriam Webster, a contronym is "is a word that is its own opposite—like 'fast', which can describe both quick movement, and lack of movement."
Contronyms are referred to as 'Janus words' after the Roman God Janus who is depicted with a double faced head, notes Britannica—a fitting symbol for contronyms that have double and opposite meanings within one singular word.
@iamthatenglishteacher Have you ever heard of contronym? They’re words that contradict themselves depending on context or form! I introduced my students to this fascinating concept by listing words like ‘fine’ (meaning both ‘good’ and ‘a penalty’) and ‘backup’ (as one word vs. two words). My students guessed terms like #synonym, #antonym, and #homonym but were shocked to discover a new category: contradicts! Watch to learn more about this mind-blowing language quirk and see how I made this lesson fun and engaging for my class! #contranym #FunWithWords #GrammarLesson #grammar #LanguageLearning #Antonym #MiddleSchoolTeacher #ESLLesson #WordPlay #EnglishTeacher #CreativeTeaching #ViralLesson #WordOfTheDay #English #HomonymVsAntonym #GrammarFun #TeachersOfTikTok #EducationalContent
Contronyms are words that have "developed contradictory meanings," and continue to make English a complex and mind-blowing language to speak and learn. As one person noted in an Reddit subforum r/words,, "And this is what makes English as a second language so challenging. That, and idioms."
