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.
Angļu valodā joprojām ir daži vārdi ar „sk”, piemēram, „<i>skirt</i>” un „<i>skull</i>”, bet tie ir tieši aizguvumi no senskandināvu valodas, kas parādījās pēc „sk” mijas uz „sh”.
