Liz
Meaning
short form of Elizabeth, ultimately Hebrew 'God is my oath'
The story
Liz is Elizabeth with almost everything formal taken away. Elizabeth comes from the Hebrew Elisheva, traditionally read as God is my oath, and English speakers have spent centuries making short forms from it: Eliza, Beth, Betsy, Libby, and Liz among them. Liz became especially visible as a name in its own right through Elizabeth Taylor, whom newspapers and audiences routinely called Liz. The US curve shows a compact midcentury story rather than a lasting replacement for Elizabeth. Liz appears in the 1930s, rises modestly through the 1950s and 1960s, and then settles into a low, steady line. That pattern fits a nickname that parents sometimes put directly on the birth certificate while many more families kept Elizabeth as the official name. Liz is therefore both complete and connected, one brisk syllable carrying the history of a much longer classic.
