krecik89 3 | 60 22 Mar 2014 #1,321English on the one hand is morphologically "simple", yet orthographically complex.Yes even when I deal with advanced level English speakers their spelling is quite bad - sometimes they choose completely different words from the spellcheck. Even I can't say my spelling is great, sometimes I write words as they sound automatically when I'm typing fast and then need to go back to check.Anyway going back to the topic. This youtube was interesting on Poles' common mistakes in their language:Some mistakes I've noticed in speech - poszłem, umię. Also, I can hear Poles self-correct their use of cases especially then they're using relative pronouns which of course define the phrase following it. I've heard six year olds make mistakes with declining the numbers when an English six year old can spend time learning new words instead of 17 ways to decline two. But on the whole I'd say the complexity of Polish makes Poles work hard on it and in general they're probably more correct in speaking their own language when compared to the English even though the language is much easier to pick up.
