Lutje (also lutke) is a prefix used in the toponym.
Lutje originates from the Germanic word lutikon or luttikon (dativus: lutika), which meant 'small'. Also luttilon and luttila were small.
Several places have the word slug in the place name. Sometimes the dialect name of a place contains lutje, especially in Gronings, such as Lutje Ulsda. Also the prefixes Luz, Lutz and Lux can be derived from lutikon or luttilon. In the nearby Friesland is the word for small lyts.
