The word TITLE derives from the Latin word titulus, which is related to the Greek word τίτλος (titlos ; title) from the verb τίω (to honor).
From the same root: titled, titling, entitle, titular
In modern Greek:
α) τίτλος: title, label [titlos]
β) τιτλο?χος: titled [titluhos]
γ) τιτλοφο?ώ: entitle, confer a title on sb [titloforo]
δ) τιτουλά?ιος: titular, assistant bishop [titularios]
τίω (tio) - τίτλος (titlos) - titulus → title
