Translation:The flag of Germany is black, yellow and red.

Why is it so different from Germany ? What is the origin of this word ? Because it's really different in French too : Allemagne
Actually, "tysk" is etymologically the same word as "deutsch". They both derive ultimately from proto-Germanic þiudiskaz.
