SPELL(1)                                                 SPELL(1)

     NAME
          spell, sprog - find spelling errors

     SYNOPSIS
          spell [ options ] ...  [ file ] ...

          sprog [ options ] [ -f file ]

     DESCRIPTION
          Spell looks up words from the named files (standard input
          default) in a spelling list and places possible
          misspellings-words not sanctioned there-on the standard out-
          put.

          Spell ignores constructs of troff(1) and its standard pre-
          processors.  It understands these options:

          -b   Check British spelling.

          -v   Print all words not literally in the spelling list,
               with derivations.

          -x   Print, marked with `=', every stem as it is looked up
               in the spelling list, along with its affix classes.

          As a matter of policy, spell does not admit multiple spel-
          lings of the same word.  Variants that follow general rules
          are preferred over those that don't, even when the unruly
          spelling is more common.  Thus, in American usage, `mod-
          elled', `sizeable', and `judgment' are rejected in favor of
          `modeled', `sizable', and `judgement'.  Agglutinated vari-
          ants are shunned: `crewmember' and `backyard' cede to `crew
          member' and  `back yard' (noun) or `back-yard' (adjective).

     FILES
          /lib/amspell
               American spelling list

          /lib/brspell
               British spelling list

          /bin/sprog
               The actual spelling checker.  It expects one word per
               line on standard input, and takes the same arguments as
               spell.

     BUGS
          The heuristics of deroff(1) used to excise formatting infor-
          mation are imperfect.

          The spelling list's coverage is uneven; in particular biol-
          ogy, medicine, and chemistry, and perforce proper names, not
          to mention languages other than English, are covered very
          lightly.
