Etymology Origin:
The word excision originates from Latin excisio, derived from excidere ("to cut out"), combining ex- (out) and caedere (to cut). It entered English in the 16th century, initially referring to surgical removal. The root cis appears in related words like incision (cutting into) and precise (cut short, exact). The term reflects a literal "cutting out," later extending to biological contexts (e.g., DNA excision repair).
