I forgot to add an explanation about the Slovak language. For us Poles, Slovak and Czech languages are as understandable as Portuguese and "Brazilian" for you. For us, the Slovak language is understandable in 90% without the need to consult any dictionaries. All our languages have a common origin in Old Slavonic. Due to less contacts with other nations, the Slovak and Skull languages seem a bit archaic to Poles, and sometimes a bit funny. This archaic character is deepening, because the governments of these countries, in fear of the disappearance of the language, introduced legal regulations regarding the naming of new inventions. They try to come up with new names at all costs so as not to use English or German names. For example: computer = počítač; printer = tlačiareň. We Poles understand these neologisms, but they are a bit funny to us, because this is what small children say when they are just starting to learn to speak.
Kind regards
