convent: [13] Latin conventus meant ‘assembly’ (it was the past participle of convenire ‘come together’, source of English convenient), but as it passed via Anglo-Norman covent into English it acquired the specialized sense ‘religious community’ (in early use it was applied to communities of either sex, but since the end of the 18th century it has come to be used exclusively for a ‘house of nuns’).

Until the mid- 15th century the Anglo-Norman spelling covent was retained in English (it survives in Covent Garden, which was formerly a vegetable garden belonging to the monks of Westminster Abbey, and may also the the source of coven [16]).

convent (n.)youdaoicibaDictYouDict
c. 1200, covent, cuvent, from Anglo-French covent, from Old French convent, from Latin conventus "assembly," used in Medieval Latin for "religious house," originally past participle of convenire "come together" (see convene). Not exclusively feminine until 18c. The form with restored Latin -n- emerged early 15c. The Middle English form remains in London's Covent Garden district (notorious late 18c. for brothels), so called because it had been the garden of a defunct monastery.
