Meaning of the baby name THEODORE.
and French (Théodore). From Latin Theodorus
(q.v.), meaning "divine gift."
French probably got it from a church in Rome dedicated to Saint Teodoro.

Wales, Greece, and Venice. By Greece is also meant all those
Greco-Slavonic countries that received their nomenclature from
Constantinople, in especial Russia, where the th is exchanged for ph, so
as to produce the word Feodor;
and the Germans, receiving it again, spell it Pheodor.
