Appreciable amounts, by definition, refers to a significant or noticeable quantity. In contrast, antonyms for appreciable amounts include insignificant, minute, negligible or trivial. These words suggest an amount that is too small to be accounted for or have any substantial impact. While appreciable amounts imply a considerable amount of money, time, or effort, the antonyms indicate a minuscule measurement that is of no real value or consequence. One could say that an appreciable amount of income may be required to purchase a house while an insignificant amount would barely cover the cost of a cup of coffee. It is essential to understand the antonyms of appreciable amounts to comprehend the degree of importance or value that is attached to a given situation.
