| .SH DESCRIPTION |
| .I Spell |
| looks up words from the named |
| .I files |
| (standard input default) |
| in a spelling list and places |
| possible misspellings\(emwords |
| not sanctioned there\(emon the standard output. |
| .PP |
| .I Spell |
| ignores constructs of |
| .IR troff (1) |
| and its standard preprocessors. |
| It understands these options: |
| .TP |
| .B -b |
| Check British spelling. |
| .TP |
| .B -v |
| Print all words not literally in the spelling list, with |
| derivations. |
| .TP |
| .B -x |
| Print, marked with |
| .LR = , |
| every stem as it is looked up in the spelling list, |
| along with its affix classes. |
| .PP |
| As a matter of policy, |
| .I spell |
| does not admit multiple spellings 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, `modelled', `sizeable', and `judgment' are |
| rejected in favor of `modeled', `sizable', and `judgement'. |
| Agglutinated variants are shunned: `crewmember' and `backyard' |
| cede to `crew member' and `back yard' (noun) or `back-yard' |
| (adjective). |

| .SH BUGS |
| The heuristics of |
| .IR deroff (1) |
| used to excise formatting information are imperfect. |
| .PP |
| The spelling list's coverage is uneven; |
| in particular biology, medicine, and chemistry, and |
| perforce proper names, |
| not to mention languages other than English, |
| are covered very lightly. |
