Theadore
Masculine · “gift of God”
Theadore puts Thea inside Theodore, which the standard spelling does not. That is a real gain, since Thea is a name in its own right, but the two names underneath are worth knowing about for a different reason: Theodore and Dorothy are built from exactly the same two Greek words, in the opposite order. God and gift; gift and God.

From Theodoros to Theadore
The story of Theadore
Theodore was a common Greek name and became a Christian one through several martyrs and a run of Byzantine figures, including a soldier-saint whose cult spread west. It reached English in the Middle Ages, went quiet, and was revived hard in the nineteenth century — America put it in the White House twice. The a-spelling belongs to the ordinary American habit of writing an unstressed vowel the way it is heard rather than the way it is spelled; the middle syllable of this name is reduced to almost nothing in speech, so it can be written o or a without changing the sound.
Meaning
gift of God
From the Greek theos, god, and doron, a gift. Reverse the elements and the result is Dorotheos, which English made Dorothy — so a brother and sister named Theodore and Dorothy are carrying the same two words in different arrangements, which almost nobody notices.

Three syllables, stress on the first. The middle vowel is reduced to a schwa in every American saying, which is exactly why the spelling can vary without anyone hearing a difference.
