authenticity
UK: ˌɔːθenˈtɪsəti | US: ˌɔːθenˈtɪsəti
n. the quality of being genuine, real, or true
n. the quality of being trustworthy or reliable
The word "authenticity" derives from the Late Latin "authenticus," meaning "original, genuine," which itself comes from the Greek "authentikos" (αὐθεντικός), meaning "principal, authoritative." The Greek root "auto-" (self) and "-hentes" (doer, achiever) combine to imply something "done by one's own hand" or "original." Over time, the term evolved to emphasize truthfulness and reliability. The suffix "-ity" (from Latin "-itas") transforms the adjective "authentic" into a noun denoting the state or quality of being genuine.
