Libby

Libby is a diminutive of Elizabeth, ultimately from the Hebrew Elisheba meaning my God is an oath or my God is abundance. It has also been used as a pet form of Isabel and Isabella. As a standalone name it has a bright, lively quality — more energetic than Liz, less formal than Elizabeth, with its own distinct personality.

Libby is a name that practically bounces. It has a double-b that gives it a playful rhythm, and the overall sound is cheerful and light. It suits smaller female dogs and cats who have big personalities relative to their size — the Cavalier King Charles Spaniel who thinks she's a Rottweiler, the tabby cat who demands center stage. Libby is also genuinely easy to call and remember, which matters in daily life more than people realize. It's a name that comes with a built-in smile.
