"Experience has been instructive to Moulder, who has learned that churches have been particularly felicitous spaces. Granted, the general public may associate the music with nightclubs and sensuality, but jazz has deep roots in the church that flowered in the form of works such as John Coltrane's 'A Love Supreme'…." — Howard Reich, The Chicago Tribune, 3 Mar. 2016
Did You Know?
The adjective felicitous has been a part of our language since the late 18th century, but felicity, the noun meaning "great happiness," and later, "aptness," was around even in Middle English (as felicite, a borrowing from Anglo-French). Both words ultimately derive from the Latin adjective felix, meaning "fruitful" or "happy." The connection between happy and felicitous continues today in that both words can mean "notably fitting, effective, or well adapted." Happy typically suggests what is effectively or successfully appropriate (as in "a happy choice of words"), and felicitous often implies an aptness that is opportune, telling, or graceful (as in "a felicitous phrase").
