You could also use ispell to find out what possible spellings of the word are available:

my @words = split(" ", "Hello, I live in a blue hoose.");
for (@words) {
        my @spell = `echo $_ | ispell -a -S`;
        if (grep /^\*/, @spell) {
                next;
        }else{
                @spell = grep /^\s*&/, @spell;
                chomp $spell[0];
                my @rest = split(/\ |\,\ /,$spell[0]);
                @rest = splice(@rest,4);
                if (scalar(@rest) != 0) {
                        print "Alternate spellings for $_: @rest\n";
                }
        }
}

Milage may vary, change as needed.

This did bring up something I would like to see in Perl (I need to check p5p). I think it would be useful to do:

my @rest = splice((my @tmp = split(/\ |\,\ /,$spell[0])),4);
or
my @rest = splice(split(/\ |\,\ /,$spell[0]),4);

But, splice() doesn't accept a split() or list assignment as it's first argument. I think it should. But, that is likely more of a discussion for elsewhere.
