Etymology: English has long attached "over-" to verbs and participles to mean "too much" or "excessively," as in "overcook" or "overwork." "Overretained" follows that pattern: the prefix sits on "retained," the past participle of "retain." "Retain" comes through Old French "retenir" from Latin "retinere," built from "re-," meaning "back," and "tenere," meaning "to hold." The core idea is holding something back rather than letting it go, and the prefix adds the sense of holding on past the proper limit.

Synonyms: kept excessively, held longer than needed

Antonyms: underretained, released, discarded
