 | | It makes contact, and then interferes with language A. Language B is going to supplant language A: the speakers of language A abandon their own language in favour of that of population B, generally because they believe that it is in their best interests (economic, political, cultural, social). |
 | | To be a substratum (and not an adstratum or a superstratum), the influence on the receiving language needs to have been substantial, something considerably more than just some borrowings or the result of a common sprachbund (an adstratum), or not the result of the dominance another language generates (a superstratum). |
 | | When the influence of another language is too remote in the past for its influence on the surviving language to be adequately characterized, 'substrate' is used by default, though the situation might have really been that of an adstratum or even a superstratum. |
