What word describes an amount that is very great?

The term "overwhelming" is used to describe an amount that is very great, often implying that it exceeds normal expectations or capacities. This word conveys a sense of something being so large or intense that it can dominate a situation or experience, leading to feelings of being overpowered or flooded by that magnitude. In various contexts, such as emotional experiences or quantities, an "overwhelming" amount indicates something far beyond the ordinary or manageable limits, highlighting its significant impact.

In contrast, "considerable" suggests a size or extent that is noteworthy but does not inherently convey the extremity or intensity associated with "overwhelming." "Moderate" indicates a balanced or average size, which does not align with the idea of being very great. Lastly, "insignificant" suggests a minimal or trivial amount, which is the opposite of what is being sought in the description of a large or impactful quantity.
