English as a language isnt bound by right and wrong. the language, the meanings. words evolve English absorbs and adapts from other languages., even within English speakers there are differences in meaning, uses and spellings.
The other issue is one that will never be perfect for all case that is in the translation between languages that is because the structures of languages differ, the way in which words are built differ. We have about 300 active language projects not every language has a direct translation for "mania" or even a single word that would describe the intent of "mania" in its current context which is a gathering, a conference, a
corroboree in the end its not what the parts of the word mean its how we as a community chose to define what the whole of Wikimania means.
