There are still some English  words with "sk," like "skirt," and "skull," but they're direct borrowings  from Old Norse that came after the "sk" to "sh" shift.
W angielskim wciąż mamy wyrazy ze "sk", takie jak "skirt" czy "skull", ale to bezpośrednie zapożyczenia ze staronordyckiego, które weszły do angielskiego po przesunięciu "sk" w "sh".
