    In that case:

    use strict; use warnings; my $term = 'Dit is het eerste het is niet het laatste Dit'; my @tlw = $term =~ /\b(\w{3})\b/g; # Now you have all the three-letter words, so count them my %seen = (); $seen{$_}++ for @tlw; for my $k (keys %seen) { print "$k occurs $seen{$k} times\n" if $seen{$k} > 1; }
