So, have you ever heard of a word in English that has two opposite meanings? We call a single word that has two contradictory meanings (they're their own opposites) contronyms. As a result of this unique characteristic, they are quite rare. But, we have a full list of these words in English. Read below how you can use them in a sentence.

As a native English speaker, you probably know when to use contronyms in the right context. But, as a non-native English speaker, it might take a bit of time to use a contronym in the appropriate situation. If you do this, it can make you sound more natural in your speech. Also, it can show your understanding of English in a social context. Moreover, for your IELTS test, it helps you show you have a wide-ranging vocabulary.

For example, in this article, we'll look at why the word 'apology' is a contronym. Now, let's explore some tips on identifying them.

What is a contronym?

The dictionary meaning of the word contronym is "a word having two meanings that contradict one another." A contronym is also called a "Janus word" or auto-antonym. It's a word has contradictory (or reverse) meanings depending on the context. Specifically, a contronym is a word with a homonym (another word with the same spelling but different meaning) that is also an antonym (words with opposite meanings). For example, the word “transparent” can mean either something that is invisible or obvious.

From our full list of 75 contronyms, you can tell that there are many examples of contronyms in the English language that we use in everyday conversation. As a result, you may also come across these words in your IELTS Speaking test. When you do this, you have to make sure you understand the context in which you’re using the word. Otherwise, you could end up saying the opposite of what you mean. Sometimes depending, on how much the contronym is used as slang, the people you are speaking with who may not know the second meaning.

How do you use a contronym in a sentence?

When you’ve read our full list of English contronyms, you’re well on your way to understanding the intricacies of the English language. But, if you want to use these contronym words correctly, check out the following examples.


  • Definition 1: A statement of contrition for an action. For example, when you are sorry about something you have done. "I owe you an apology for running late to our meeting this morning."

  • Definition 2: As a defence to something you've done wrong. For example, when you find an excuse for something. "The worker's excuse that the elevator was busy was a weak apology for running late to a meeting."

To dust

  • Definition 1: To remove dust. For example, when you are cleaning the house. "As part of my weekly cleaning routine, I dust the cupboards in my bedroom."

  • Definition 2: To sprinkle with soil or dust. For instance, when you decorate a cake. "Before serving the cake, you should dust it with a layer of powdered sugar."


  • Definition 1: Moving quickly or at high speed. "The driver was fined by the police for driving too fast."

  • Definition 2: Stuck or to make stable. "The ship was held fast by the anchor chain."


  • Definition 1: A person of nobility. For example, a member of one of the five ranks (duke, marquess, earl, viscount, or baron) of the British peerage. "Peers attended the royal wedding in the church, while commoners waited outside to see the royal newlyweds."

  • Definition 2: One that is of equal standing with another. For example, a colleague or a classmate. "Students are encouraged to have their assignments proof-read by their peers."

To sanction
