24 .I Spell
25 looks up words from the named
26 .I files
27 (standard input default)
28 in a spelling list and places
29 possible misspellings\(emwords 
30 not sanctioned there\(emon the standard output.

32 .I Spell
33 ignores constructs of
34 .MR troff (1)
35 and its standard preprocessors.
36 It understands these options:
37 .TP
38 .B -b
39 Check British spelling.
40 .TP
41 .B -v
42 Print all words not literally in the spelling list, with
43 derivations.
44 .TP
45 .B -x
46 Print, marked with
47 .LR = ,
48 every stem as it is looked up in the spelling list,
49 along with its affix classes.
50 .PP
51 As a matter of policy, 
52 .I spell
53 does not admit multiple spellings of the same word.
54 Variants that follow general rules are preferred
55 over those that don't, even when the unruly spelling is
56 more common.
57 Thus, in American usage, `modelled', `sizeable', and `judgment' are
58 rejected in favor of `modeled', `sizable', and `judgement'.
59 Agglutinated variants are shunned: `crewmember' and `backyard'
60 cede to `crew member' and  `back yard' (noun) or `back-yard' 
61 (adjective).

86 .SH BUGS
87 The heuristics of

89 used to excise formatting information are imperfect.
90 .PP
91 The spelling list's coverage is uneven;
92 in particular biology, medicine, and chemistry, and
93 perforce proper names,
94 not to mention languages other than English,
95 are covered very lightly.
