That dictionary is the same dictionary used by Wordle. It was extracted from the Wordle app. I’m pretty sure all of them are valid English words, which ones do you think are not valid English words?
Abacs is an example. But since you posted this, I looked some of them up and see there are a whole lot of uncommon words, but not necessarily non-words. A lot of the words I was questioning are actually foreign words that transferred to English for when speaking about the foreign concepts. Eg: Abuna.
Except I didn't find a definition for abacs, but it's probably just not in every dictionary.
