UK[ˌɒnɪst tə ˈɡʊdnəs]US[ˌɑːnɪst tə ˈɡʊdnəs]
adj
genuine and sincere; not false or artificial
Etymology
The phrase "honest to goodness" emerged in the late 19th century as an emphatic, folksy oath or asseveration, invoking truthfulness before God ("goodness" being a euphemistic substitute for "God"). It follows a pattern common in English where a prepositional phrase solidifies into a compound modifier, similar to "down-to-earth" or "over-the-top." The literal sense of swearing to one's honesty evolved into its current function as a reinforcing adjective meaning "authentic" or "real." Its charm lies in its colloquial, earnest tone, transforming a solemn pledge into a descriptor of unpretentious genuineness.
