I'm still getting the same problem after I begun using a different variable instead of $line, why does it still refuse to ignore my words? 
my @words;
my %search;
my $first;
my $second;
my $line;
my @ignore = qq(a and the this i me us our ok abc);

my $file = "abc.txt";
my $count = "0";

open (FILE, $file) or die "Error $!";
@words = <FILE>;
chomp(@words);
close FILE;

my @search= @words;

  foreach my $line (@words) {
    $line =~ tr/A-Z/a-z/;
    foreach my $ignore (@ignore) {
      $ignore =~ s/\b$ignore\b//;
    }
  }

foreach my $line (@words) {
# splitting words on a white space but allowing contractions and hyphe
+ns
    while ($line =~ /([[:alpha:]]+(?:'[[:alpha:]]+)?)/g) {
        if (exists ($search{$1})) {    
            $search{$1}++;    
        } else {
            $search{$1}="";
            $search{$1}++;
        }
    }
}

while (($first,$second)=each(%search)) {
    print "$first -- $second\n";
}
