Our focus is on the word unknown, an essential vocabulary item for your IELTS preparation.
Word type: Unknown can function as both an adjective and a noun in English.
Meaning: As an adjective, unknown describes something that is not known, identified, or familiar. As a noun, it refers to a thing or person that is not known or identified.
Word history: The word unknown comes from Old English uncnawen, where un means not and cnawen means known.
This combination has been used for centuries to describe things that are not familiar or recognized.
Antonyms: Known, familiar, recognized, identified.
Synonyms: Unfamiliar, unidentified, mysterious, strange, uncharted.
Examples use in sentences: In your IELTS speaking test, you might say, The effects of climate change on small island nations are still largely unknown.
For the writing task, you could write, Many unknown factors contribute to the success of a business in a new market.
In a reading passage, you might encounter a sentence like, Scientists are exploring unknown regions of the ocean floor to discover new species.
Common errors in use: One common mistake is confusing unknown with undiscovered. While they are similar, unknown simply means not known, while undiscovered specifically implies something that exists but has not yet been found or recognized.
Another error is using unknown when unfamiliar would be more appropriate in personal contexts. For example, instead of saying This food is unknown to me, it is more natural to say This food is unfamiliar to me.
Understanding and correctly using the word unknown can help you express ideas about unfamiliar concepts, unexplored areas, or uncertain outcomes in your IELTS tasks.
