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

This is probably the best explanation that a certain spelling should be accepted I have seen on here, because it's so damn true.

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.
