I could actually get almost all of the last third correctly by choosing the option that's the longest, has a semicolon, or a coma.
Aside from that, I didn't like that most of the words only had one or at most two definitions that sounded viable.
A lot of these words have either Latin or Greek origins, for most questions you can deduce the correct answer by asking the question: "Which of these would make sense to develop into a separate word through the mostly non-modern history of the language?".
I would enjoy it way more if all four options sounded equally viable, and I couldn't deduce the correct answer without actually being sure about the meaning of the word. I understand that coming up with choices like that for each question is way harder if you actually validate all of them manually.
I got a score of 76000 best estimate with 85 being correct, even though English is not my native language and I'm not that good at it.
