Elizabeth comes from Hebrew and is traditionally rendered "God is my oath," a meaning it shares with several related names across languages. The name has long carried associations with steadfastness and quiet devotion rather than public piety, and its many nicknames have let it carry very different tones depending on the bearer.
Give not judgment before thou knowest the intention of the querent; for many ask they know not what, nor can they express what they intend. - William Lilly (1602.-1681.)
