Even Greener Pastures

In Polish we have many loanwords coming to our language at various stages. Some are acquired recently, mainly due to the technological revolution, while the others are used for centuries.
Poland has been created in 10th century from several Slavic nations. During over the 1000 years it was divided several times and reunited. Some parts of it were incorporated into other countries for centuries. Some of these countries forced their language and culture trying to replace ours. The other thing is that Polish language has been used in literature and administration since 16th century. Until then Latin was the official language used for writing. And I can imagine the spoken Polish wasn't homogenous (I remember significant differences between regions even in the times I was a child). It's probably similar to Italy or Spain where everyone speaks the local language or dialect with his family and friends.
So the impact of other languages on Polish was enormous.
I read about various attempts to get rid of some loanwords, but inventing Polish neologisms in place of the well known loanwords, usually leads to an artificial weird language. I've read a text called "Siedząc w szlafroku" (sitting in a bathrobe / dressing gown) where the author starting from attempts done to replace German "Schlafrock" in Polish with "podomka", points to the fact it comes from Latin "domus", and further tries to reinvent the new words to those we use everyday. The conclusion was that we would have to recreate our language to do it.
