A person or thing that is kept or remains in a particular situation or place for a longer time than expected.
The holdover from last year's team helped the new players adjust more quickly.
Holdover → It is formed from "hold" (from Old English "haldan", meaning to keep or maintain) and "over" (meaning above or beyond). The word "holdover" refers to something that is kept or maintained beyond a certain time or period.
Think of something that is 'kept' ('hold') 'beyond' a certain time ('over') — that's what a holdover means.
