What does surplus mean?
Surplus means an amount that is left over after something has been used or supplied, or more generally, a state of having more than is needed. It appears frequently in practical and economic contexts: a business may have surplus stock, a government may report a budget surplus, and a market may experience a surplus of a particular product. The word often suggests resources that have not been needed at the present time, but it can also imply valuable potential that might be put to better use. As an adjective, surplus describes goods, labor, capacity, or funds that exceed requirements. As a verb, to surplus someone is to dismiss them because their job or position is no longer necessary. The word is standard in both British and American English and is more formal than casual alternatives such as extra, although its precise economic and administrative senses are especially useful for discussing resources, demand, and budgets.
An amount or quantity remaining after use, need, or requirements have been met; an excess of resources or supply.
"The hospital reported a surplus of donated medical supplies."
The term is common in business, government, and economic contexts.
Excess or available in greater quantity than is needed.
"The farm sold its surplus grain to local markets."

To dismiss someone from employment because their position is no longer required.

From the Latin for “above,” surplus has always pointed to what lies beyond what is needed.

Etymology of surplus
The word entered English through French, from Latin surplus, the neuter past participle of superare, meaning “to go beyond” or “to exceed.” Latin superare was built on super, meaning “above” or “over,” the same broad root found in superior, supreme, and superlative. The English word developed in the sense of an excess or remainder and later acquired the adjectival and employment-related uses.
