Re^2: Concatenating strings with different length

[choroba]

Or even:

#!/usr/bin/perl
use warnings;
use strict;

#use Data::Dumper;

my %fragments;

while ( my $line = <DATA> ) {
    chomp $line;
        my @words = split / /, $line;
        for my $i (0 .. $#words - 1) {
            push @{ $fragments{$words[$i]} },
                 join ' ', @words[0 .. $i-1, $i+1 .. $#words];
        }
}

for my $term ( keys %fragments ) {
    print "There are $term " . ( join ' and ', @{ $fragments{$term} } 
+) . ".\n";
}

__DATA__
big businesses
fast red cars
big smart companies
fast light planes
fast animals
big bad wolves
small bad girls
bad growling bears

Output:

There are small bad girls.
There are light fast planes.
There are growling bad bears.
There are bad big wolves and small girls and growling bears.
There are big businesses and smart companies and bad wolves.
There are smart big companies.

Excellent, choroba!

Building on your and GrandFather's suggestions, there's the following:

#!/usr/bin/perl
use warnings;
use strict;
use Lingua::EN::Tagger;

my %fragments;
my $p          = new Lingua::EN::Tagger;
my @adjectives = qw/nervous nutty obnoxious outrageous
  panicky repulsive scary selfish sore
  tense terrible testy thoughtless tired
  troubled upset uptight weary wicked worried/;
my @stems = (
    "It's been said that there were many",
    'Goldfish spoke with',
    'There were three',
    'People used to see 42',
    'There were quietly-roaming groups of'
);

while ( my $line = <DATA> ) {
    chomp $line;
    my $adjective = $adjectives[ int rand $#adjectives + 1 ];
    $line = $p->add_tags($line) =~ s/<nns>/$adjective /gr =~ s/<.+?>//
+gr;
    my @words = split / /, $line;
    for my $i ( 0 .. $#words - 1 ) {
        push @{ $fragments{ $words[$i] } },
          join ' ', @words[ 0 .. $i - 1, $i + 1 .. $#words ];
    }
}

print "Once upon a time...\n\n";

my @sentences;

for my $term ( keys %fragments ) {
    my $stem = $stems[ int rand $#stems + 1 ];
    push @sentences, "$stem $term "
      . ( join ' and ', @{ $fragments{$term} } ) . '.';
}

print join ' ', @sentences;

print "\n\nThe times have certainly changed.\n\nThe end.";

__DATA__
big businesses
fast red cars
big smart companies
fast light planes
fast animals
big bad wolves
small bad girls
bad growling bears

Sample output:

The end.

Well this works if you know the common word is the first word. IF not, then this never works. In the cases such as "modern game" and "classic game" it will not work.
