Antithesis is a figure of speech that involves juxtaposing ideas, words, or phrases with opposite or contradictory meanings within the same grammatical structure, creating a striking contrast and emphasizing the difference between the two elements.
This figure is used to highlight the opposition between concepts and make an impact on the reader or audience.
For example, the famous phrase by Charles Dickens, “It was the best of times, it was the worst of times,” is an example of antithesis, as it contrasts the ideas of the best and the worst in the same sentence.
