Sara f. Hebrew שָׂרָה 'princess'.
The name of the Biblical wife of Abraham. Septuagint: Σαρρα; Vulgate: Sara; Wycliffite Bible (1395): Sara.
Her original name was Sarai (in the Vulgate and the Wycliffite Bible; Σαρα in the Septuagint), and in some cases, it is hard to differentiate forms of Sara from forms of Sarai). The usual English spelling of the name was Sara; forms with the intrusive h were always less common. The name was used by both Christians and Jews in the Middle Ages, but was rare outside of Britain and France.
