What does "excess" commonly refer to in everyday use?

The term "excess" is commonly understood to signify an amount that surpasses what is adequate, necessary, or typical. In everyday use, when something is described as being in excess, it implies that there is an abundance or surplus of it, often to the point where it may be unwelcome or problematic. For instance, if one were to talk about "excess sugar," it would indicate a quantity of sugar that goes beyond healthy or recommended levels.

This understanding captures the notion of abundance associated with the word "excess," whereas the other options present concepts that are related to sufficiency, accuracy, or balance, which do not align with the implications of surpassing a normal or required level.
