Abstract
According to one influential view, something which we might have reason to think is a language, is not proven to be such until it has been translated. I will try to show, to the contrary, that it is necessary to appeal to factors which are independent of translation in order to establish that it is indeed a language which has been translated in the first place. If this is right, it follows that proof of languagehood, so far from depending on translation, is in fact logically prior to translation.
