An archaic term for a winning look, an amorous glance, or a flattering smile intended to charm or seduce someone.
From French 'bel regard' meaning 'beautiful look,' combining 'bel' (beautiful) and 'regard' (look/glance). Used in English during the Renaissance and early modern period when French courtly manners heavily influenced English nobility.
In Shakespeare's time, people actually had a word for a seductive glance—'belgard' was the romantic art of looking at someone in just the right way to win their affections!
