What is the meaning of the name Lillybet ?

Lillybet is English in Origin.

Blending vintage charm with a floral lilt, Lillybet is a modern English diminutive ultimately rooted in Elizabeth, from Hebrew Elisheva, “God is my oath.” The spelling with double l and y likely reflects influence from Lily plus the familiar -bet/-beth ending, aligning it with cognate pet forms such as Lilibet and Lillibet. Meaning therefore circles back to Elizabeth’s devotional promise while carrying a light, botanical feel.

As a given name, Lillybet is rare and contemporary, while its near-twin Lilibet has deep royal resonance: it was Queen Elizabeth II’s childhood nickname and reentered headlines when the Duke and Duchess of Sussex chose it for their daughter in 2021. Variant spellings and related forms include Lilibet, Lillibet, Lilybet, Lilibeth, Lilybeth, and Libbet; short forms range from Lily/Lili to Beth, Bet, Libby, Bess, and Betty.
