Meaning & origin

Adalei is a modern coinage that first appeared in U.S. birth records in 2005, reflecting the early-2000s trend of creating distinctive yet familiar-sounding names. It reached its peak popularity in 2012, when it ranked 11,932 and was given to approximately 1 in 229,610 girls. Since 2018, its usage has been in decline, aligning with a broader shift away from the -lei suffix trend. The name has not been concentrated in any particular state, suggesting its use is scattered across the country. Adalei exemplifies the inventiveness of contemporary American naming practices, where parents blend sounds from traditional names like Ada or Adeline with popular endings to craft a unique identity.

Adalei is a modern invented name, emerging in the United States in the early 2000s. It appears to be a blend of sounds from established names such as Ada or Adeline, combined with the popular -lei ending (also seen in names like Kaylei or Halei). Its rise reflects a broader trend of creating unique, melodic names from familiar components.
