A situation in which quantity supplied is greater than quantity demanded.

Explanation:

A surplus refers to a situation in which we have more of an asset or resource than is being used. In other words, the quantity we need (demand) is less than the quantity that is being produced (supply). While a surplus might not necessarily be damaging, it can be very negative in some cases, such as in situations that deal with perishable items, as the items might be spoiled before they can be used, leading to permanent losses.
