Streets can have multiple names because of multilingualism. Streets in Brussels often have a Dutch name and a French name, both languages being official: for example "" (Dutch) and "" (French), both meaning "Mountain Street". While the older streets were originally named in Dutch, some more recent ones, conceived in French, have been retranslated. For instance "Boulevard Charlemagne" was retranslated from "Karlemagnelaan" to "Karel de Grotelaan", and Rue du Beau Site in Ixelles from the literal "Schoonzichtstraat" to the more idiomatic "Welgelegenstraat". Occasionally there is confusion over which is the best translation, as is the case with the "Chaussée de Waterloo" in St-Gilles, Brussels, which is variously rendered as "Waterlosesteenweg" and "Waterloosesteenweg". Similarly, the name may change when the street lies on or across a border between areas with different languages: (Kerkrade, Netherlands) / (Herzogenrath, Germany), both names meaning "New Street".
