cmdr_flashheart: I wasn't picking on OP for starting the thread, but giving reasons for why words which seem unnecessarily complicated to us might have good reasons for existing the way that they do; the OP said, "there are words out there that are really complicated for no obvious reason", hence my post.
The more we read, the more we might understand why certain words exist. That's all, really :]
I do understand, as such - but I do also think that enjoyable words exist to allow to write in-between the lines, as in French of Rousseau, but also simply to inquire.
What is a word you like? Pick your language even, and just post it! :-)
"Die Finsternis" or darkness in German - I have always wondered about this word. Someone can tell?
