Meggie is a diminutive form of Margaret, which derives from the Greek word "margarites" meaning "pearl." This affectionate nickname has a sweet, friendly quality that has made it endure through generations, though it's less common as a formal given name. Meggie gained some popularity in the English-speaking world during the 20th century, particularly after the publication of Colleen McCullough's novel "The Thorn Birds" (1977), which featured a protagonist named Meggie Cleary. The name has a youthful, energetic feel and is often associated with warmth and approachability. While not ranking high on most popularity charts as a standalone name, Meggie continues to be used as both a nickname and given name, especially in Scotland, Ireland, and other parts of the United Kingdom.
