The English language is a mystery to many non-speakers. This is largely due to the contradictions within the language itself, such as English words that have opposite definitions despite being spelled the same way. If you’re an English speaker, you do not pay much attention to these things. But for English language learners, these types of words add to their confusion with the language.
Do you know what the words that are spelled similarly and have two different meanings are called? They are called contronyms. The simplest explanation is that they are words that have opposite meanings.
Several nyms comprise the English language. Words that mean the same thing are synonyms. Words that sound the same but have different spelling, such as pear and pair are homonyms. Antonyms are the opposite meaning of a word. Heteronyms are words spelled similarly but pronounced differently.
A contronym is one word that has opposite meanings, which depends on the context of its use. It seems illogical that one word can have two different meanings, which can be the exact opposite of the other at times. For example, the word cleave means to cling, to adhere or to stick to something or someone. But it can also mean to cut, to split or to separate.
A contronym has other names, too. Some people call it contronym while others refer to it as autoantonym. More descriptive terms include antilogy, self-antonym, enantiodrome and antagonym. There’s still another term that many people use to refer to contronyms – Janus words. It was derived from Janus, an Italian deity of old, said to be heaven’s doorkeeper whose head has two faces, one in front and one at the back.
The English language continues to evolve, including its parts. People, especially native speakers of English use contronyms in their daily conversation, but it may be tricky for learners of the language.
Contronyms develop over time as a result of constant use. For example, according to its etymology, the word blunt used to mean obtuse (person) or dull (weapons, tools) when it was used from the 12th century to the late 14th century. But around the 1580s, it became a word to mean sharp, referring to abrupt manner or speech, which takes on the context of making an unceremoniously made or direct comment. Another example is the word bolt, an Old English term whose original meaning (as a verb) is to fix or fasten something. Centuries later, bolt is also used to mean spring into sudden action, which could have been derived from bolt (noun) that refers to a missile or projectile such as an arrow.
One vital thing for English language learners to remember is to understand the context in using a word so that they will not make the mistake of saying something that is contradictory to the intended meaning.
This knowledge is essential in interpretation and translation as well. If a contronym is used in a different context, it can distort the whole meaning of the conversation or a sentence. If you need translation or interpreting services, ensure that you collaborate with a professional and native-speaking translator or interpreter, so as to avoid these types of mistakes.
The development of contronyms is also due to pronunciation changes through the years. Let’s look at the word cleave again. It means to join together and to split apart. It came from two Old English words, cleofan (split apart, separate) and cleofian (also clifian, cliofian) (adhere, stick together). Through years of use, the two words started to sound the same and later merged to become cleave.
Here’s another interesting one. Let is a word that used to mean stop, delay, obstruct, impede. It came from the Old English term lettan. Another Old English word, lætan means to leave undone, leave behind, bequeath or to allow. The original words later formed the contronym, let.
In some cases, the difference is the variant of English one uses creates the contronyms. In a parliamentary procedure, to table a bill means that the bill could be discussed, considered or reconsidered in British English. In American English however, it means to suspend or postpone the consideration.
If you love languages, you’ll have fun with contronyms. But for many people, it can be confusing. So instead of getting confused, here are some examples of contronyms, which could be words that you use every day or see often. You may not even realize that you are using them in two different contexts because you are so used to them.
Here are more contronyms for you to use:
Remember that when using contronyms, you have to be aware of the words’ context, to ensure that you are relaying the right message.
