What is "rekkem"

Rekkem is a section of the Belgian city of Menen, in the province of West Flanders. Until 1977, it was an independent municipality. It was called Retchème in Picard. In 1173, the village was still called Rekkem, similar to Reclinghem in Artois and to Rijkegem ( Tienen), which were founded by the Viking Rikiwulf in 876 .
