Meaning & origin
Betsi, a spelling variant of Betsy, first appeared in U.S. records in 1944, making it a relatively recent addition to the pool of Elizabeth-related nicknames turned given names. Though it has never ranked in national top-1000 lists, it experienced its highest usage in 2006, when more girls were named Betsi than in any other year. Despite its low overall frequency, the name has enjoyed a stable trajectory in recent decades, with a slight uptick during the 2000s. Betsi remains a rare choice, a modern respelling of a classic diminutive that maintains the familiar sound of Betsy while offering a distinctive spelling.
Betsi is a variant spelling of Betsy, which itself originated as a diminutive of Elizabeth. Elizabeth comes from the Hebrew name Elisheva, meaning 'God is my oath'. Betsy became an independent given name in the 18th century, and Betsi is a modern respelling that emerged in the mid-20th century, first recorded in the United States in 1944.
