The Scandinavian name Dette, pronounced "DEHT-tuh", is of uncertain origin but believed to have been coined as a pet form of the Old Norse female given name Theodhildr. Theodhildr, in turn, comes from the Old German elements 'theod' meaning people and 'hild' meaning battle. Therefore, Dette could be interpreted as "little fighter". It is extremely rare, with few recorded instances worldwide. The name is more commonly associated with Norway, where it has been documented since the late 19th century. Despite its scarcity, Dette has no known variants or related names, making it a unique choice for parents seeking an uncommon yet meaningful moniker for their daughter.
"The name Dette had a notable birth year of 1962 with 6 births, followed by another peak in 1965 with 7 births. However, it appears that the popularity of the name began to decline from 1967 onwards, with each subsequent year seeing either fewer or the same number of births as the previous one."
