Definitions

Etymology: Sadie is a pet form of Sarah, and its history is mostly a story about naming habits rather than a change in meaning. Sarah comes from Hebrew "Sarah", a name that most often gets glossed as "princess" or "noblewoman", though the exact sense is debated among scholars. Diminutives like Sadie were built by adding a "-ie" or "-y" ending to a shortened form, a common way in English to turn a formal name into an affectionate one. The name took off in the English-speaking world largely as a standalone given name rather than only a nickname. Its use spread widely in the United States and Britain, and it is now often registered on birth certificates as a full first name in its own right, so many people named Sadie have never been called Sarah at all.
