Sufix should be accepted for suffix, why? Because I can't spell it right and I'm mad.

the validity of that depends on what you define as XL, maybe they want to compliment the buyer

Maybe their XL size differs in each country, to compliment the buyer. That would be a very good marketing strategy

Only a theory, not proven.

Level 70
Jun 17, 2022
So is gravity, but the current theory works better than any other competing theory. The previous prevailing explanation of it being vestigial (and serving no function) is also ‘only a theory,’ but the common practice is to assume the correctness of the currently prevailing theory until if/when a more sound explanation arises. If we assume everything to be wrong until proven, we end up in a paradox in which the appendix does and doesn’t serve a purpose because each theory must be wrong, on account of neither being proven.

^^When used in a scientific context, the word "theory" should never be immediately preceeded by the words "only a"

^Paradox would be a good one to add

The appendix in most animals, called the caecum in anything that actually uses the thing, has a very big role in digestion. In humans it is a storage place for beneficial gut bacteria so I would argue it does have a function

Well, I think it's referring to "orthodox" with a lowercase "o", not "Orthodox" with a capital "o", as in "Eastern Orthodox" or "Greek Orthodox." (Not that those names didn't come from the little "o" meaning of orthodox, but you know what I mean...).

postfix is an acceptable answer. It is synonymous with Suffix. It is a less common word for suffix. Plus, it ends with x.

Here in Maryland, most duplexes aren't apartments (rentals); they're owned houses, complete with mortgages, etc. They're much like single-family houses, except they have a common dividing wall down the middle, usually built of heavy masonry to try to contain fires.

No. Crucifix is crucifix. If you took a long time to spell it, it's because you don't know how to spell it. What about sphynx? Isn't that an acceptable spelling?

A duplex is one apartment on two levels. Usually with the living room, dining room, kitchen and perhaps a powder room on the main floor

and the bedrooms and full baths on the upper floor.

I don't think that is the real estate definition of Duplex, I think the quiz question is correct.

I would assume the term could vary by city, county, state, country, etc. or whatever governing body defines it. Including down to the real estate contract that defines it to the satisfaction of the parties involved.

It's a method of making a white sauce like a bechamel or a cheese sauce. You start by melting the fat (usually butter) then mix in the flour to a paste. That's the roux. You can then slowly add the liquid (usually milk) a little at a time.

In my case, "Sphinx" doesn't readily occur as a valid spelling.

I tried "Sphynx" a couple of times, it didn't take, so I shrugged and figured I was on the wrong track (because the head was a woman's or something? I dunno). "Sphinx" didn't occur to me at all.

I finally did get it, in the dying seconds, after spending a couple of minutes wracking my brains for an answer to that one last question. Finally, with about 3 seconds to spare, I typed "sphinx" in, completely not expecting to get it right, but more out of desperation because I had no other ideas.

TL;DR "Sphynx" should absolutely be accepted as a type-in.

Yeah, it’s the other way round, a spiral staircase is not actually a spiral, it’s a helix. Because the English language is designed to mess with people.

The appendix is now believed to have a function relating to the gut microbiome: Source. The proposition that it has no function seems implausible given that it is often infected, causing serious disease. On the other hand, the coccyx has no known function aside from the common function of blood cell production shared by all bones.

The clue for "unisex" needs to be changed. It's well established that gender lies on a spectrum so "either gender" is grammatically incorrect.

When my forebears were fighting for gay liberation, thank God we didn’t ruin it by antagonising the rest of the population by scouring every piece of text for ‘unacceptable’ grammar, even in the most innocuous of places and in the most throwaway of lines. Because we wouldn’t have progressed to where we are, they’d have just added “irritating pedants” to their list of reasons why they already hated us.

And before I’m accused of being anti-trans, or one of those LGB trogs, that would be wrong. I’m as pro trans rights as I am ‘pro’ my own rights or anybody elses. But, as a strategy, this inflexible, pedantic and, frankly, annoying grammar/vocabulary policing is not the best, it’s bad PR at best. At worst, I’d say it’s actually offensive to trans people (yes, even if the agitator is trans themselves). Because the trans people I know have endured a lot worse, and to suggest everyone of them is so thin-skinned as to be offended by the grammar of a quiz clue trivialises their real struggle.
