It estimated 74k words for me, but I feel this might be inflated; much of the time when I didn't know the answer - I could vibe guess it just as you did it. The distractor answers weren't convincing enough. For starters, when an answer was based on deconstructing the word into common English words, that ruled it out. After all, if it was, then it wouldn't have been obscure.

A tangent: writing distractors for multiple choice questions is hard. From the exams I know (excluding those whose nature precludes it, such as based on calculation or rote memorization) the only that does this brutally well is LEK (Polish medical graduate exam). It's nigh impossible to vibe guess it at more than random chance for someone outside the field.

In case of online quiz you can have a "competition" between distractors:

1. start by having much more distractors than needed and pick randomly

2. for each measure the probability of it getting clicked (clicks/times it's shown)

3. show the most frequently clicked distractors more often

Yeah, as I researched the topic of multiple choice exam design, seems the rule of thumb is to reject outright any distractors that are chosen by less than 5% of test takers.

Yeah I also got exactly 74k. Stuff like “xylologist” I guessed had to do with vegetation because of “xylem”, whereas xylophone player was too on the nose. Then again, maybe knowing xylem in the first place makes 74k reasonable.

66k for me, but I didn't get that word, instead I got ones like Hippopotomonstrosesquippedaliophobia, Flibbertigibbet, and Brobdingnagian... which the latter two interestingly do show up in my keyboard's word completion suggestions.

Yeah I guessed that one right because xylophone player sounded like a trap.

I don't understand how they rank words though, some extremely common words like xenophobia were ranked as high as much more obscure ones.

Haha. Yeah I figured Xylo- (wood) + sth. related to mono-poly so wood-seller made sense. Never have heard of this word before

[pclmulqdq]

I think the test was vibe coded, because a xylologist is someone who studies wood, not someone who sells wood. I am not sure if "xylolgist" was the exact word, though.

xylo- = wood; -logy = study

Indeed from M-W: "a branch of dendrology dealing with the gross and the minute structure of wood"

in casual use you might also be able to guess it from context, so i think it’s a wash

[onionisafruit]

It would have been nice to have an “i don’t know” button. Instead I decided to select the first option for words I didn’t know instead of trying to figure them out. Although when I got to the final group I couldn’t resist trying to figure them out. It estimated 61k for me.
