This is probably for those whom English language is not native language. Is there a word that you find difficult to say? It doesn't have to be some scientific word, just regular word. For example, I know in my country words 'girl' 'world' are pronounced really weird. Like the letter 'r' is killing! :D

I find it difficult to say 'wardrobe' and 'irrevocably'. I don't even know why but I do.

What about you? :)
