  • rolig 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. Sep 26, 2008

  • sionnach 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. Dec 1, 2007

  • mollusque 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. Dec 1, 2007
