| Citazioni | The 'substratum theory' attributes sound-change to transference of language: a community which adopts a new language will speak it imperfectly and with the phonetics of its mother-tongue [...] the substratum theory can account for changes only during the time when the language is spoken by persons who have acquired it as a second language. |
