Theo

Theo is a given name and a hypocorism.

Many names beginning with the root "Theo-" derive from the Greek word Theos, which means God, for example:

Feminine names

Many other names beginning with "Theo-" do not necessarily derive from Greek, but rather the old Germanic "theud", meaning "people" or "folk". As these names are uncommon today, and in the ancient times they were not spelled with the element "Theo", it is unlikely this nickname was ever applied to these individuals. These names include:
