Link the two clauses with the conjunction. What do they mean?
Weil am Rhein is the name of a town situated in the Südbaden area in southern Germany.
As its name suggests, the town lies on the banks of the River Rhine. The outer limits of the town border France to the west, and Switzerland to the south. When three countries border each other in this way, it is known as a 'tripoint' in English and called ein Dreiländereck (literally: a three country corner) in German.
In 1913, a marshalling yard, used to separate railway wagons on to different tracks, was built to link Weil am Rhein to the neighbouring Swiss city of Basel. The name Weil is believed to come from the Roman name Willa, and so does not mean 'because' in this instance.
But how apt that a town of this name should link two towns in two different countries, just as weil links two clauses.
