What Teagan means
Teagan means little poet, from the Irish Tadhg, a poet or philosopher, with a diminutive ending. The beautiful reading widely repeated online cannot be traced to any Irish word and should be treated as unfounded.
Where Teagan comes from
Teagan anglicizes Tadhgán, a diminutive of Tadhg, an Old Irish name meaning a poet and by extension a philosopher — poets held formal legal standing in early Irish society, which is why the name carried weight. Tadhg was so common in Ireland that it became a generic term for an Irishman, in the way Paddy later did. The surname Ó Tadhgáin gives Teagan and Tegan. The attractive or beautiful meaning repeated across name sites has no source in Irish and appears to have been introduced by twentieth-century baby-name books. First-name use is modern and roughly even between girls and boys.
