Olivia

Olivia is a Latinate name derived from the Latin word oliva, meaning olive or olive tree, a plant long associated in Mediterranean cultures with peace, wisdom, and prosperity. The name was notably popularized by William Shakespeare, who used it for the wealthy countess in his comedy Twelfth Night (1602), though records of its use as a given name predate the play. It spread widely across the English-speaking world and beyond, becoming one of the most common girls' names in many countries by the early twenty-first century. Related forms include Olive, the Spanish and Italian Olivia, and the masculine cognate Oliver.
