What is the meaning of the name Lyllibet ?

Lyllibet is in Origin.

Lyllibet is a modern respelling of Lilibet, an English pet form of Elizabeth that arose from a child’s pronunciation of her own name - most famously Queen Elizabeth II, called "Lilibet" by her family. It functions as a diminutive built on the -bet/-beth ending of Elizabeth, ultimately from Hebrew Elisheva, meaning "my God is an oath" or "God is my oath." The Lyllibet spelling adds visual flair and hints at the lily-like Lili- sound, sometimes evoking the flower’s associations with purity, though its roots lie in Elizabeth rather than Lily.

Usage has been rare and intimate, seen in 20th-century Britain within family circles, and returned to public view after the 2021 birth of Lilibet Diana Mountbatten-Windsor. As a given name, Lyllibet remains uncommon and whimsical, aligning with trends for vintage nicknames as stand-alone names. Related forms and variants include Lilibet, Lillibet, Lilibeth/Lillibeth, Lilibette, Lilabet, and wider Elizabeth diminutives such as Libby, Lizzie, Elsie, Eliza, Beth, and Bette.
