Meaning & origin

Kailah is a modern feminine given name that first appeared in U.S. records in 1982, a product of the late 20th-century trend for names ending in -ah or -la. Its popularity peaked in 2002, when it reached its highest rank, but it has been declining since 2001. In 2025, the name ranked 5,410 with a one-in-69,881 frequency, placing it in the lower echelons of name usage. The spelling Kailah is most common in Florida, suggesting a regional pattern of use. As a variant of the more familiar Kayla, it shares the same phonetic appeal while offering a distinctive spelling. Parents drawn to Kailah often appreciate its soft, melodic sound and contemporary feel, though its meaning remains ambiguous due to its modern coinage. The name has not been associated with any notable historical figures, preserving its fresh, unburdened character.

Kailah is a modern variant of Kayla, which itself emerged in the late 20th century as a blend of names like Michaela or a feminine form of Kyle. Its popularity in the United States rose during the 1990s and 2000s, influenced by the trend of names ending in -lah. The spelling with an 'h' is a stylistic variation, not rooted in any traditional language.
