Imagine you’re in an IELTS speaking test, discussing a complex global issue. Your examiner nods approvingly as you present a plausible solution to the problem.
But what exactly does plausible mean, and why is it such a powerful word to use in your IELTS exam? Today, we’re exploring this sophisticated vocabulary item that can elevate your language skills to band score 8.0 and beyond.
Word type: Plausible is an adjective. It’s used to describe ideas, arguments, or explanations.
Meaning:
Plausible means seeming reasonable, probable, or believable. It refers to something that appears to be true, valid, or acceptable, especially in the absence of proof.
In the context of IELTS, using this word demonstrates your ability to evaluate and present ideas critically.
Word history: The word plausible has Latin roots. It comes from the Latin plausibilis, meaning worthy of applause or approval.
This origin gives us insight into its current meaning of being seemingly worthy of belief or acceptance.
Antonyms: To better understand plausible, let’s look at its opposites. Antonyms include implausible, unlikely, improbable, unreasonable, and far-fetched.
These words describe ideas or explanations that are hard to believe or accept.
Synonyms: Synonyms for plausible include credible, believable, likely, feasible, reasonable, and conceivable.
These words all convey a sense of something being possible or believable, but plausible often implies a degree of skepticism or the need for further proof.
Examples use in sentences: Let’s explore how to use plausible in various contexts relevant to IELTS tasks.
In an IELTS essay, you might write: The researcher presented a plausible explanation for the decline in bee populations, citing the increased use of pesticides and habitat loss.
For the speaking test, you could say: While time travel remains a fantasy, scientists have proposed plausible theories about bending space-time to achieve faster-than-light travel.
In a reading comprehension context, you might encounter: The detective considered several plausible motives for the crime before identifying the true culprit.
And in a listening test, you might hear: The economist offered a plausible forecast for economic growth, based on current market trends and historical data.
Common errors in use: Be cautious when using plausible. Some common mistakes include confusing it with possible or probable.
While these words are related, they have distinct meanings. Possible simply means something could happen, probable means it’s likely to happen, but plausible suggests it seems reasonable or believable.
Another error is using plausible for definite facts. Remember, plausible implies that something seems true but isn’t necessarily proven.
For instance, it would be incorrect to say: It’s plausible that the Earth orbits the Sun. This is a proven fact, not just a plausible idea.
Mastering the word plausible and using it accurately in your IELTS exam can significantly enhance your vocabulary score.
It shows your ability to discuss ideas with nuance, evaluate arguments critically, and express sophisticated concepts.
Remember, plausible ideas are those that seem reasonable or believable, even if they’re not yet proven.
By incorporating this word into your active vocabulary, you’re one step closer to achieving that band score 8.0.
