Meaning & origin

Betti is a feminine given name that emerged as a respelling of Betty, itself a classic diminutive of Elizabeth. First recorded in the United States in 1916, the name reached its peak popularity in 1946, when it was most commonly used. Despite never appearing in the national top 1000 rankings, Betti maintained a stable presence throughout the mid-20th century, particularly during the 1940s. Its usage reflects a broader trend of simplifying or personalizing traditional names. The name's trajectory suggests it has remained consistently used at low levels, without dramatic rises or declines. While no specific states recorded significant use, Betti fits within the style of mid-century American naming conventions, alongside other soft-sounding, nickname-derived girl names. The name's etymology ties it to the enduring legacy of Elizabeth, one of the most historically significant female names in the English-speaking world.

Betti is a diminutive or variant spelling of Betty, itself a pet form of Elizabeth. Elizabeth derives from the Hebrew name Elisheva, meaning 'God is my oath.' The spelling Betti emerged in the early 20th century, likely as a respelling to create a distinctive form. It saw peak usage in the 1940s.
