Addison

Son of Adam, through an inherited surname.

Addison comes from an English and Scottish surname meaning “son of Adam”. The connection runs through Addie, a familiar form of Adam. As a given name, Addison is used for both girls and boys: the word “son” explains its surname history rather than limiting who can bear it. In English, Addison has three syllables, /ˈæd.ɪ.sən/, with the first syllable stressed. The opening vowel is the one in English “cat”, and the final vowel is unstressed. That firm opening followed by a softer ending gives the name a friendly, slightly tailored feel. Addie and Addy are established short forms. They offer a useful change of register: Addison keeps the fuller surname shape, while Addie feels more informal and affectionate. If you like a name with some weight on paper but a light everyday form, that contrast may be its strongest attraction.

Etymology: From an English and Scottish patronymic surname formed from Addie, a pet form of Adam, and the element meaning “son”.
