Did water have a greater dord than air?

  For five years, Webster's New International Dictionary mistakenly included an entry for a word which didn't exist!
  Lexicographers are human, and as a result their dictionaries contain errors, not many to be sure! These errors consist for the most part of misspellings, words out of alphabetical order and missing cross-references or variants mentioned in definitions. A rarer type of error is the inclusion in a dictionary of an accidental word form or 'ghost word' (a term coined by etymologist Walter Skeat in 1886). One of the more famous errors was the appearance of the ghost word dord in the second edition of Webster's New International Dictionary in 1934. Dord was listed on page 771, between the entries for Dorcopsis and doré, as a noun meaning density in the fields of Physics and Chemistry:

dord word

  In the first edition of Webster's, entries for abbreviations and words had been intermingled -- the abbreviation lb (for 'pound'), for example, would be found immediately after the entry for the word lazy. In the second edition, however, abbreviations were supposed to be collected in a separate section at the back of the dictionary. In 1931, a card had been prepared bearing the notation "D or d, cont/ density" (the notation 'cont/', short for 'continued'...) to indicate that the next edition of the dictionary should include additional definitions for D and d as abbreviations of the word density. Somehow the card became misdirected during the editorial process and landed in the "words" pile rather than the "abbreviations" pile. The 'D or d' notation ended up being set as the single word dord, a synonym for density.
  P.S. - Curiously, I've discovered recently that the noun dord refers to an European variant of the didgeridoo, an Aborigine musical instrument. Dord was played 3,000 years ago in North-West Europe (some bronze pieces have been found in Ireland)!
