harmonious

Etymology

It is borrowed from Middle French harmonieux, also armonieux,^{[2][3][4][5][6]} from harmonie (“harmony”), also armonie,^[2][3][5] with its ending matched to -ous.^[3][5] The French adjective is recorded from the 14th century.^[3][4] The Shorter Oxford takes the English word as harmony with that suffix.^[7] The French noun goes back through Latin harmonia to Ancient Greek ἁρμονία (harmonía, “means of joining; agreement, concord of sounds”),^[4][5][1] which Wiktionary connects with ἁρμόζω (harmózō, “to fit together”), from Proto-Indo-European *h₂er- (“to join, fit together”).^[1]

Earliest recorded meaning

Of people, singing, playing or speaking tunefully: 1530, in Palsgrave's Lesclarcissement de la langue francoyse.^[3][2] Etymonline gives the 1520s for "sounding together tunefully",^[4] and Dictionary.com 1520–30.^[8]

Semantic evolution

The word began as a musical term: of sounds blending pleasantly together, it is recorded from about 1550, in the Complaynt of Scotland.^[3] The non-musical use, of parts that agree and form a consistent, pleasing whole, followed in 1638;^[3][4] it had been prepared by the noun harmony, used for agreement of feeling since the late 14th century.^[4] From 1724 the adjective also described people or groups free from disagreement.^[3] Johnson (1755) put the non-musical sense first, "adapted to each other; having the parts proportioned to each other", and the musical sense second.^[6]
