IELTS Vocabulary: Understanding and Using ‘Corollary’
Learn the meaning, usage, and importance of the word ‘corollary’ for IELTS success. This video covers its definition, word type, history, synonyms, and common usage errors to help you effectively incorporate it into your English expression for higher band scores.
Mastering advanced vocabulary is crucial for achieving a high band score in IELTS, and today we’re focusing on a word that will elevate your academic and professional English: corollary.
Word type: Corollary is primarily used as a noun, though it can occasionally function as an adjective.
Meaning: A corollary is a proposition that follows from and is often appended to one already proved. In simpler terms, it’s a natural consequence or result of a fact or principle.
In mathematics, it refers to a statement that readily follows from a previous theorem.
Word history: The term corollary comes from the Latin word corollarium, which originally meant a garland or small gift of money.
It later evolved to signify a deduction or an additional inference in logic.
Antonyms: While corollary doesn’t have direct antonyms, some words that convey opposite ideas include cause, origin, source, and premise.
Synonyms: Some synonyms for corollary include consequence, result, effect, outcome, upshot, and inference.
Examples use in sentences: The rise in ocean temperatures is a direct corollary of global warming. As a corollary to the company’s new work-from-home policy, employees reported higher job satisfaction.
The theorem about the angles of a triangle has several important corollaries in geometry. Common errors in use:
One common mistake is confusing corollary with correlation. While a corollary is a natural consequence, a correlation merely implies a relationship between two things, not necessarily a cause-and-effect link.
Another error is using corollary too loosely for any result or outcome. Remember, a true corollary should follow logically and directly from an established fact or principle.
To effectively use corollary in your IELTS speaking and writing tasks, ensure you’re applying it to situations where there’s a clear, logical consequence.
This demonstrates a nuanced understanding of cause and effect, which is highly valued at band score 8.0 and above.
By incorporating corollary into your vocabulary, you’re not just learning a new word; you’re gaining a powerful tool for expressing complex relationships and logical outcomes.
Practice using it in your own sentences, and soon it will become a natural part of your high-level English expression.
