The writing has been simplified somewhat, with most accent marks being omitted. For example árþúsund in Old Norse (millennium) became arþusund in Skræligen.
Grammar is much closer to English, given the last few centuries of English's presence on the island. (Author's note: this requires more research and development.)
Where words are similar to their English counterparts, the Skræligen words have morphed slightly towards their English counterparts. (Author's note: this requires more research and development.)
To a lesser extent, the dialect of English spoken on Skrælige has picked up on the vocabulary of Skræligen.
