Tilje

Short form of Otilie, one of several Norwegian spellings of a female given name going back to Latin Otilia, originally Odilia, a Latinised form of Old High German Odila and Otila, pet forms of names such as Oda. The Old High German names are formed from the Germanic name element reflected in *audaz (“wealth, riches”), with a pet-name or diminutive ending. Compare Danish Tilje, Swedish Tilje and English Tilly (“female given name”).
