I apologize in advance. I know this question has been posed many times but I cannot quite understand the difference as I am only a beginner in French.
Consider the following phrases:
1) Le musée du Bronze. I understand that 'du' is used here since we are talking about a specific museum. Or is my understanding wrong?
2) La porte de la véranda (balcony door). The explanation that I read was this: A veranda is kind of a room made of glass, and the door "belongs" to this room as it is a part of its walls.
3) la maison de poupée. This can be interpreted as: The house "belongs" to the doll.
In the second and third sentences, both define the same relation of "belonging". Then why are different prepositions used?
