Adisyn is a modern American feminine name reimagined from the Old English surname Addison, meaning “son of Adam,” and refreshed with the trendy “-syn” ending to create a distinctive identity. Pronounced AD-ih-sin (/ˈædɪsɪn/), it first appeared in US birth records in the late 1990s and rose steadily, peaking in the mid-2010s before settling near rank 940 in 2024 with nine recorded births. Its formation echoes Latin nomenclature traditions while embracing contemporary spelling trends, reflecting a broader shift toward creative adaptations of classic names. Associated with ingenuity and individuality, Adisyn offers parents a concise yet richly rooted option that bridges heritage and modern style.
