This toponym also appears comparably late (like Kūolka and Kuoštrõg) and it is difficult to determine in which language it originated . V. Kiparsky has suggested that its earlier name might have been the Baltic Sareyken mentioned in 16th century documents as a populated place between Ģipka and Kolka.[1]
Morphologically from mustā (“black”) + num (“pine forest”).
