The word "insertion" originates from Latin insertio, derived from inserere ("to insert"), combining in- (into) and serere (to join, attach). The root sert evolved from serere, reflecting the idea of joining or placing something into another. Over time, insertion expanded from literal physical placement (e.g., inserting an object) to abstract uses (e.g., genetic insertion). The suffix -ion standardizes it as a noun denoting action or result.
