The name Enid is a girl's name of Welsh origin meaning "life, spirit". Enid and is often added to lists like Mythological Baby Names for Girls and discussed in our forums with posts like "Spelling Bee Name Game".
From the experts:
This Celtic goddess and Arthurian name may sound terminally old-ladyish to many ears--but so did names like Ella and Etta not so long ago. So Enid is yet another forgotten four-letter E-possibility: she's has been M.I.A since 1954.
You might not know it to look at her, but Enid is Welsh, from the word meaning 'life' or 'soul.' Back in the Age of Chivalry, to call a woman 'a second Enid' was the greatest of compliments, as she was a legendary romantic figure, revived in Tennyson's Idyll of the Kings. In more modern times, Enid is the title of a Bare Naked Ladies song and a quirky character in the quirky film Ghost World.
