Answer:
To change a toponym of one place is not so easy to do. This process is usually connected to political changes in different parts of the world.
The toponym change is a sensitive topic, as the name of a place represents the symbol of that place, its identity, and ethnicity. One toponym is related to that place and to people from that place.
Explanation:
Also, when changing the toponym, people should take care of the new name, if it will be in a context of nationalism or internationalism. People connect te name of the place with the location of the place, so it is not easy to adopt a new name, as part of identity is fading.
If the toponym is changing, it has to fit the society, what is the meaning of that new toponym, is it related to the nation, the historical background of the toponym, etc. Those are elements that are influencing the acceptance of a new toponym.
