Thanks Anonymous Monk pointing to Data::Dumper. I checked both arrays

The result show clearly, that the structure of the elements is different. An example:

print Dumper @allwords;

...

$VAR9 = 'hat

';

...

print Dumper @cleanwords;

...

$VAR6 = 'hat';

...

I selected the word which should match. In @allwords the single quotation mark appears in a new line. Maybe it's caused by newline? and I should chomp the elements?

I chomped it like this:

chomp (@allwords);

Result:

';AR9 = 'hat

The single quotation mark of the predecessing word appears in the sam line.
