Origins
The English noun "integrity" traces its origins to the Latin term "integritΔs," which is the nominatβββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββive form of a noun derived from the adjective "integer." The Latin "integritΔs" denotes wholeness, completeness, soundness, purity, and blameless conduct. The word entered English usage around the mid-15th century, likely through Middle French "intΓ©gritΓ©," which itself was borrowed from Latin. The earliest attestations in English appear circa 1450, a period when many Latin-derived terms entered the language via French, particularly in the realms of philosophy, law, and morality.
At the core of "integrity" lies the Latin adjective "integer," meaning whole, complete, untouched, uninjured, sound, or upright. This adjective is a compound formed from the negative prefix "in-" meaning "not," combined with a root related to the verb "tangere," which means "to touch" or "to handle." The verb "tangere" descends from the Proto-Indo-European root *tehβg-, which carries the sense of touching, handling, or grasping lightly. This root is well-attested in Latin and has yielded a family of words associated with contact or touch, including "tangent" (touching at a point), "tangible" (able to be touched), "contact" (touching together), "contagious" (touching throughout), "contaminate" (to touch throughout, often with a negative connotation), and "tact" (originally the sense of touch, later extended metaphorically to skillful handling of social situations).
The adjective "integer," therefore, literally means "not touched," or more figuratively, "untouched" in the sense of being uncorrupted or unbroken by external interference. This notion of being whole and unimpaired is central to the semantic development of "integrity." The Latin "integritΔs" abstracted this quality into a noun expressing the state or condition of being whole, sound, and morally blameless.
Latin Roots
From this Latin root, several related English words have emerged, sharing the semantic field of wholeness and completeness. "Integrate," meaning to make whole or bring parts together, and "integral," meaning forming a necessary or essential part of a whole, both derive from the same Latin stem. The philosophical and mathematical senses of "integral" developed later, particularly in the calculus of Leibniz and Newton, where "integral" refers to a quantity representing the whole or the sum of parts. These specialized senses, while more technical, still rest on the fundamental idea of wholeness inherent in "integer."
The transition from Latin "integritΔs" to English "integrity" involved the mediation of Middle French "intΓ©gritΓ©," which preserved the meaning of moral soundness and wholeness. The English adoption retained these senses, emphasizing not only physical or structural completeness but also moral uprightness and honesty. Thus, a person described as having "integrity" is etymologically understood as someone who remains "unbroken" or "untouched" by dishonesty or corruptionβtheir moral character is whole and unimpaired.
It is important to distinguish this inherited Latin root from later borrowings or semantic shifts. The core components "in-" and "tangere" are inherited Latin elements, not borrowed from other languages, and the formation of "integer" and "integritΔs" is a native Latin derivation. The English word "integrity" is a direct borrowing from Latin via French, rather than an inherited Germanic term or a later neologism.
Modern Legacy
"integrity" is a word rooted in Latin morphology and semantics, combining the negative prefix "in-" with a root related to touching, to convey the idea of being untouched, whole, and unimpaired. Its journey into English reflects the transmission of moral and philosophical concepts from Latin through French into English, preserving a rich semantic field that encompasses both physical wholeness and ethical soundness. The etymology of "integrity" thus illuminates the conceptual link between physical completeness and moral uprightness that the word continues to express in modern English.
