In the manner or style of a convent; following the customs or rules of monastic community life.
From conventual + -ly (Old English suffix forming adverbs). This adverb allows description of actions or behaviors performed according to convent traditions and regulations.
This rare adverb reminds us that medieval monasteries had such specific, detailed ways of doing everything—speaking, eating, working, praying—that writers needed a word to describe 'in the convent way.' It's precision for a vanished world.
