Etymology

insure = in<into> + sure<secure>

  • in: A Latin prefix meaning "into" or "upon," here implying action toward certainty.
  • sure: Derived from Latin securus (secure, free from care), evolving through Old French seur to mean "confident" or "guaranteed."

Etymology Origin:
The word "insure" emerged in late Middle English (15th century) from Anglo-French ensurer, combining en- (a variant of in-) and seur (secure). It originally meant "to assure" or "make certain," later specializing in financial protection against risk. The shift reflects the logic of "putting security into" an agreement—tying the morphemes' meanings to contractual safeguards.
