English church and West Frisian tsjerke, but Dutch kerk, Low German Kerk, Kark, and German Kirche
The early Anglo-Frisian and Old Saxon were spoken by intercommunicating populations, which led to shared linguistic traits through assimilation. English and Frisian have a proximal ancestral form in common before their divergence. Geography isolated the settlers of Great Britain from Continental Europe, except from contact with communities capable of open water navigation. This resulted in Old Norse and Norman language influences on Modern English, whereas Modern Frisian was subject to contact with the southernly Germanic populations, restricted to the continent.
