The class intimations of these images are plain enough, though Polidori in his exhaustive effort of preservation did not scruple to include upper-end or highland stretches — Canal Street, say, with its two-storied, sometimes stuccoed domiciles set back on lawns, including a pert example of old-fashioned flat-roofed, parallelepiped-pure modernism, with Art Deco stripes and a little penthouse.

mollusque commented on the word parallelepiped
I saw Laiane's comment on parallelopiped and thought, isn't it spelled parallelipiped? Turns out it's "parallelepiped": the derivation is parallelus + epipedum. In technical writing, parallelepiped is used more than 95% of the time (in Google Scholar), but in more general writing (Google Books), only 60% of the time, with parallelopiped getting 27%, parallelipiped 12%, and parallelapiped 1%. Perhaps parallelogram and parallelism are influencing the spelling of parallelepiped? Interesting that Weirdnet lists both parallelepiped and parallelopiped.

sionnach commented on the word parallelepiped
clearly, this is the word which would get me eliminated from the spelling bee, because if you had asked me, I would have chosen parallelapiped. Though, apparently, at the time I entered it into Wordie, parallelopiped seemed like the correct choice. Probably, as mollusque surmises, by analogy with parallelogram.

rolig commented on the word parallelepiped
According to Dictionary.com, this word is derived from Greek as follows: parállél(os) parallel + epíped(on) plane, nominal use of the neuter form of epípedos flat, equiv. to epi- upon + pédon ground. So the -epi- element is constituent to the word; -piped alone makes no sense in etymological terms. I would guess that this word is properly pronounced parallel-EH-pee-ped.
