Etymology: The verb in question is a common misspelling of a standard English word that means to take away one quantity from another. The correct form is "subtract," derived from Latin roots rather than "substract," which is not recognized as a proper English word. "Subtract" entered English in the 17th century, borrowed from the Latin "subtrahere," itself composed of "sub-" meaning "from below" or "under," and "trahere," meaning "to draw" or "pull." The Latin verb conveyed the idea of "drawing away" or "taking away," which neatly captures the mathematical operation we know today. This root is also the source of related words like "attract" and "detract," each involving the idea of pulling or drawing. The formation of "subtract" follows a clear morphological path: the prefix "sub-" plus the verb stem "tract," from "trahere." The mistaken variant "substract" likely emerges from a blend of "subtract" and "extract," the latter sharing the "tract" root but with the prefix "ex-" meaning "out of." This confusion is understandable given that both words involve removal or taking away, but "substract" has never been standard. In summary, the correct verb comes from Latin "subtrahere," passed into English as "subtract," meaning to take away. The spelling "substract" is an error influenced by the similar-sounding "extract," but it has no legitimate etymological basis.
