Can language be delinked from culture? Maybe. But can a language survive without a culture to encompass it? If you strip culture from a language, wouldn't the language would become toneless and meaningless? Yes, you can call something a 'net' or a 'fish' at a basic level. However in one culture one might say, "You must cast your net to catch the fish" it's plain what it means and it is meaningful, but for someone without the cultural context, it's a head scratcher and may wonder what fish are you talking about?

I'm too, my native language isn't the one I am writing here. I have lived in quite a few different places. Culture is not something I could make up for myself as I go along, I don't think anyone could do so in isolation. I took in the different bits of cultures that i have experienced through, sometimes to the dismay of those around me. I appreciate the perspective that cultures create languages, and without the cultural reference the language would cease its importance and would die.
