How to choose a good namespace name? (Linguistically)

Question

English in not my native language, therefore it is a little more difficult to pick a good name for a namespace. One example to make you see my problem a bit better:

We have a set of classes that have to do with the way a company is organized (we can create organizational charts with it). Currently the namespace is CFW.CoreSystem.Organizational. Is this a good name?

What is linguistically the best way to name a namespace? (CFW.CoreSystem.Configuration is better than CFW.CoreSystem.Configurables).
