‘Sael’ makes it sounds more expensive and silly
They surely meant to spell ‘sale’, but unfortunately, the magic didn’t happen.
‘Uitverkoop’ is still a really long word, and everywhere you look, you’ll see ‘sale’.
My inside joke about ‘sael’ is cheap though: in old Dutch, many words were spelled with ‘ae’ and eventually ‘shortened’ to just an ‘a’, like with some streets names in Amsterdam were ironically richer people live.
