What does Esther mean?
Widely glossed as 'star', most often derived from Old Persian 'stara' (compare modern Persian 'setareh', and Greek 'aster'). The exact root is debated: some scholars instead link it to the Babylonian goddess Ishtar (associated with Venus), and a Hebrew folk etymology ties it to the root s-t-r ('to hide'). Included with that caveat.
