Teddie

Teddie is an English pet form of Edward or Theodore, both of which carry distinct origins — Edward derives from the Old English elements ead (wealth, fortune) and weard (guard), while Theodore comes from the Greek Theodoros, meaning gift of God. The nickname form Ted, from which Teddie developed, arose through the medieval English habit of rhyming substitution, similar to how Bill emerged from William. Teddie is used for both males and females, though it appears more frequently as a feminine diminutive in modern usage. Related forms include Ted, Teddy, Ed, Eddie, Thea, and Dora.
