Meaning & Origin
A female given name transferred from the surname.
Addyson is a girl's and boy's baby name of Old English origin, a creative feminine spelling of Addison, from the English surname meaning 'son of Adam' or 'son of Addy,' where Adam derives from Hebrew adam (earth, mankind).
The -yson ending feminizes this popular surname name, following the pattern of Madysyn, Emersyn, and Allyson. Addison has been a leading girls' name since its adoption as the female protagonist of Grey's Anatomy's spinoff, and Addyson offers an alternate spelling with the same warm, confident sound.
