The short answer
Adaline is a feminine English name that Behind the Name defines as a "variant of Adelina." Adelina in turn comes "from a Germanic name that was derived from the element adal meaning 'noble' (Proto-Germanic *aþalaz)", so Adaline means, at root, "noble". Behind the Name gives the English pronunciation /ˈæd.ə.laɪn/, that is AD-ə-lyne with a long final syllable, which distinguishes it from the -lyn spellings Adalyn and Adalynn. Its variants are Adalyn, Adalynn, Addilyn, Adeline, Adelyn and Adelynn, and its short forms Ada, Addie, Addy and Aline. In the United States Adaline ranked #208 for girls in 2025.
Meaning and etymology
Behind the Name's entry for Adaline reads "Variant of Adelina" and lists the root as aþalaz. The Adelina entry supplies the meaning: a Germanic name derived from the element adal, "noble", Proto-Germanic *aþalaz. Unlike Adalyn and Adalynn, which Behind the Name describes as Adeline plus a suffix, Adaline is labelled plain English rather than English (Modern), and its pronunciation keeps the long -line ending of Adeline. The related-name list is the broad Adeline family across Europe: Alina, Adelina, Adéla, Adèle, Adela, Ada, Lina and their kin.
