Have you ever heard of a perpetual motion machine? It’s a hypothetical device that would continue to function indefinitely without any external energy source.
While such a machine is impossible according to the laws of physics, the concept introduces us to our GRE vocabulary word of the day: perpetual.
Word type: Perpetual is an adjective.
Meaning: Perpetual means continuing forever or for a very long time without interruption.
It describes something that is endless, constant, or permanent.
Word history: The word perpetual comes from the Latin word perpetualis, which means continuous or universal.
It entered the English language in the 14th century and has been used to describe ongoing or never-ending phenomena ever since.
Antonyms: Some antonyms for perpetual include temporary, finite, intermittent, and transient.
Synonyms:
Synonyms for perpetual include eternal, everlasting, endless, ceaseless, and continuous.
Examples use in sentences:
The perpetual snow on the mountain peaks never melts, even in the hottest summers. The couple made a perpetual vow to love and support each other through all of life’s challenges.
Scientists are searching for perpetual energy sources to combat climate change and reduce reliance on fossil fuels.
Common errors in use: One common error when using the word perpetual is confusing it with frequent or recurring.
While perpetual implies something that is constant and uninterrupted, frequent or recurring events happen often but with breaks in between.
For example, it would be incorrect to say The restaurant offers perpetual discounts. Instead, you could say The restaurant offers frequent discounts or The restaurant has a perpetual discount policy.
Another mistake is using perpetual to describe something that lasts for a long time but eventually ends.
For instance, saying Her perpetual cold lasted for two weeks is incorrect because a cold, no matter how long it lasts, is not endless.
Understanding the nuances of words like perpetual is crucial for success on the GRE. This word not only helps you describe continuous or never-ending phenomena but also demonstrates a sophisticated vocabulary.
Remember, in the context of the GRE, perpetual knowledge and practice are key to achieving a top score.
