Kalmar
The Old Swedish place name Kalmarnir or Kalmarnar contains the joint kalm, 'stone cairn' and the plural form arnar of arin, 'gravel island'. The name may have referred at the earliest to the area of Stensö (Stone Island) just south of the town. Kalmar had a large German population in the Middle Ages and possibly influenced by the name of the German town Wismar (from the high german wisa and mara, both meaning 'swamp') a reduction of the suffix may have taken place.
