Livvy is a diminutive form of the name Olivia, which is a feminine given name in the English language. The name Olivia is derived from the Latin word 'oliva', meaning 'olive'. Both Oliva and Olivia were Latinate forms used in English-speaking countries as early as the 13th century. The name gained popularity through its use in literature and popular culture, particularly through Shakespeare's character in 'Twelfth Night' and later by notable figures such as Olivia Newton-John and Olivia Kendall.
