Supplanter
Deigo is a rare variant of Diego, which is the Spanish form of James. It ultimately derives from the Hebrew name Jacob, meaning 'supplanter' or 'one who follows'. While often mistaken for a misspelling, it occasionally appears as a distinct phonetic variation in Spanish-speaking communities.
