Ailanny is a modern American coinage, a variant of Ailany, which is most often explained as a blend of names like Aileen and Leilani or as a Spanish-flavored respelling of the Hawaiian Leilani, "heavenly flowers". It is especially popular in Spanish-speaking families in the United States. Ailanny has shot up from number 3477 in 2023 to number 932 in 2025, its first year in the top 1000.
