From the Greek Θεόδωρος, joining theos, meaning god, with dōron, meaning gift. Dorothea is built from precisely the same two elements in the opposite order, which makes the pair one of the neatest mirror images in European naming.

Etymology

From the Greek Sebastos, meaning venerable or revered, which was the Greek rendering of the Latin title Augustus. Sebastianus therefore meant a man from Sebaste, a city named in the emperor's honour, so the name reaches its meaning through a place rather than directly.

#4Popularity (2025)#16

Theodore combines the Greek 'theos' (god) and 'doron' (gift). President Theodore Roosevelt established its rugged-yet-warm persona. After decades of dormancy, it has rocketed from #266 in 2009 to the top 10 — one of the greatest comeback names ever.

Cultural Note

Sebastian comes from the Latin 'sebastianus' meaning 'from Sebastia' (modern Sivas, Turkey), associated with the Greek 'sebastos' (revered). Saint Sebastian and Shakespeare's 'Twelfth Night' established its classical-literary pedigree.
