what is the purpose of (.) you added in front of every line ?

That's the string concatenation operator, see perlop. '<td><a href="' . $href_to_what{$word} . '">' . $word . '</a></td>' concatenates those five strings together into a single string. In this case it's the same as writing "<td><a href=\"$href_to_what{$word}\">$word</a></td>".
