You have a lot of duplication in your code so I cleaned it up a bit and removed some redundant code.

    TSO => 'TSONGA',
    TSW => 'TSWANA',
    VEN => 'VENDA',
    XHO => 'XHOSA',
    ZUL => 'ZULU',
    );

my %words;

for my $file ( <korpus*.txt> ) {
    $file =~ /\Akorpus([A-Z]{3})\.txt\z/ or next;
    my $type = $1;
    exists $file_types{ $type } or next;
    local $/;
    open my $FH, '<', $file or die "Cannot open '$file' because: $!";
    @{ $words{ $type } }{ grep length, split /\n/, <$FH> } = ();
    }
