Addisyn

Addisyn is a spelling of Addison, an English patronymic surname meaning “son of Adam.” The first part comes through Addie, a familiar form of Adam, while the ending expresses descent. The surname’s original wording does not dictate who can use it as a first name today.

The y in Addisyn makes a visible distinction from Addison while usually leaving the spoken name unchanged. Addie can be used as a short form, although it also belongs to other name families and is not exclusive to this one. Addisyn’s history is best understood through the older surname, rather than assigning a new meaning to the altered final vowel or treating the name as a combination of unrelated syllables.
