Etymology
the word 'insure' entered english in the late middle english period, originally meaning 'to assure' or 'to make sure'. it is derived from the anglo-norman french 'enseurer', which itself is based on the latin elements 'in-' (into, upon) and 'securus' (secure). the core semantic logic involves placing someone or something into a state of security or certainty, particularly against financial loss. this concept of providing a formal guarantee of security against risk evolved into the modern commercial sense of arranging financial compensation in case of specified misfortunes.
