Nominull, your remarks about language here and above seem off (although my experience is narrower than cousin_it's, since I'm only bilingual, German is coming slowly, with little motivation). Each language has its sound, influencing the way you can use it for different tasks. Of course, you can accurately communicate a deeply understood concept in any language, by describing it redundantly, but that doesn't apply to the sum total of everyday use, in particular to viewing the language as a tool for refining your concepts.
