Meaning and origin of Teagan
Teagan is an Irish name that is usually said to mean “little poet (from Tadhg)”.
Teagan comes from the Irish surname Ó Tadhgáin, derived from the personal name Tadhg, which is traditionally translated as poet or philosopher. The -án ending is a diminutive, so the name is often explained as little poet. Teagan became popular as a girls' name in the late twentieth century, though it is also used for boys. It feels spirited and fresh, with a crisp Irish sound. Spellings vary, including Tegan, Teigan and Tiegan.
