Antonyms of the word ‘trivial’ include ‘important’, ‘significant’, ‘essential’, and ‘crucial’.
To understand why these words are considered antonyms, it helps to look at the meaning of ‘trivial’. The term refers to something that is not important or has little value. Therefore, its antonyms denote a sense of high significance or value.
For instance, something that is essential is necessary for the existence or functioning of something else, making it the opposite of trivial, which indicates irrelevance. Similarly, ‘important’ and ‘crucial’ imply a high degree of significance that trivial things lack.
In summary, when discussing concepts or items, using these antonyms helps convey their importance or relevance in a given context.
