Baugruppe is a German word that means "assembly group". It is used to describe a group of parts that are made up of individual components that are put together to make a whole. For example, a car has a baugruppe that includes the engine, transmission, brakes, and other parts that work together to make the car run. Imagine playing with Lego blocks; each Lego block is a smaller part, but when you put them together they make a bigger piece, like a car. Baugruppe means the same thing – different parts put together to make something bigger.
