Which word refers to an abundance or large quantity of something?

The word "profusion" specifically refers to an abundance or a large quantity of something, often conveying a sense of richness or extravagance. It denotes an overflowing supply or a lavish quantity, emphasizing not just the presence of a lot but also the idea that it is more than what is necessary or normal.

The choice "excess" conveys a sense of quantity that goes beyond what is considered normal or sufficient, but it can carry a negative connotation, suggesting that there may be waste or an undesirable overflow. "Ample" suggests a sufficient quantity but does not inherently imply abundance to the same degree as "profusion." Finally, "surplus" refers to an amount that is more than what is needed, often in a practical context, such as finances or resources, but it lacks the same visual richness or connotation of abundance found in "profusion." Thus, "profusion" best captures the essence of a large, impressive quantity.
