Yeah... I have noticed that... those words are easy!
I think a lot of those words may have come from German or French though.. but they happen to be something similar in English (there is a LOT of English words that are almost the same as a French word).
I don't think either Russian or English are the hardest languages to learn. Apparently Korean is harder to learn than both Japanese and Chinese.
In Europe, Finnish is an incredibly hard language; the grammar is as hard as Russian and it constantly makes up one word to say something that other languages would use two or three words from. Also the words are not similar to the words in any other European language apart from Estonian. Even though I went to uni there for almost a year, and it's my neighbouring country and I know tons of Finns, I can only understand a few words here and there. Luckily they also speak Swedish there.
