   4. pl. Breeches; shortclothes. [Slang] --Dickens.

   5. (Phonetics) A short sound, syllable, or vowel.

            If we compare the nearest conventional shorts and
            longs in English, as in ``bit'' and ``beat,''
            ``not'' and ``naught,'' we find that the short
            vowels are generally wide, the long narrow, besides
            being generally diphthongic as well. Hence,
            originally short vowels can be lengthened and yet
            kept quite distinct from the original longs. --H.
                                                  Sweet.

   {In short}, in few words; in brief; briefly.

   {The long and the short}, the whole; a brief summing up.

   {The shorts} (Stock Exchange), those who are unsupplied with
      stocks which they contracted to deliver.
