I do not know the difference between the following words: •"um" and "über"<--- I don't know the difference between their use as "about". •"als" and "denn" <--- I don't know the difference between their uses as "because", and "than". And also, I am quite unsure if the notes I have taken from the following webpage are true, so if you are someone who knows enough to tell me wether these things are correct or incorrect, please do so! http://germanforenglishspeakers.com/other/conjunctions/ I DO have questions about wether or not specific things on this page are correct, so if you want me to specify them, please let me know.
