It is sometimes very hard to name things well.
The name either becomes so unspecific that it is just as useless, or it gets so long that nobody will use it.
This gets worse the "deeper" the math goes, but for me it never was a real problem, as you usually learn the definition together with the name.
For really simple compounds, names are more or less settled and consistent (with some exceptions).
But as soon as your compound starts to get more complex (think organic chemistry) all the sudden, it becomes nigh impossible to consistently name things. There are tons of compounds with the same chemical formula that are regionally named differently. Even worse, there are tons of compounds with the same chemical formula that are actually different things due to how the compound is arranged. (Good ole carbon chains).
