They’re not recognised words. You have to beat the crap out of autocorrect in order to type them. I heard someone pronounce “aswell” as “azwull” the other day. It’s two separate words!
I know “albeit” and “nevertheless” exist and language evolves, but how has this come about? People my age (41) know that it is incorrect but have adopted it. What makes a person take up a spelling error? Fashion or insecurity that they have been getting it “wrong” all this time?
It’s fascinating and infuriating.
