implant comes from French implanter, from Late Latin implantare ('to engraft, plant in'), from in- ('in') + plantare ('to plant'), from planta ('sprout, plant'). Morphologically, the prefixed shape matters: the initial element belongs to the recorded formation and helps explain the modern form's surface analysis. In present English, the verb sense is "to insert or fix firmly, especially within the body or mind", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as plant, transplant, and supplant, and in derivatives such as implantation, implanter, and implantable. Its semantic neighborhood includes insert, embed, instill, and fix, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Latin implantare and Latin planta.
