A female given name from Ancient Greek.
"Margaret is a popular female given name derived from the Ancient Greek word for pearl."
From the name of a legendary third century saint, from Middle English Margaret, from Old French Margaret (French Marguerite), from Latin Margarita, from Ancient Greek μαργαρίτης (margarítēs, "pearl"), ultimately from an Indo-Iranian source. The same source, through folk etymology, has produced Old English meregrot ("pearl", literally "stone or pebble of the sea"), related to Old Saxon merigrita, merigriota ("pearl"), Old High German merigrioz, equivalent to mer- + groat.
