Theo

Theo is a short form of longer Germanic compound names beginning with the element theud, meaning people or nation, most commonly Theodore (meaning gift of God, from Greek) or Theobald (meaning bold people). It has been used as an independent given name in English, German, Dutch, and Scandinavian languages, gaining particular popularity in the nineteenth century and again in recent decades. The French form Théo follows the same pattern, serving as a familiar form of Théodore or Théophile. Related names include Theodore, Theodora, Theobald, and Theophilus.
