Difference between 推迟, 拖延, 延迟, and 推延 Hello, I was interested in knowing the differences in meaning between 推迟, 拖延, 延迟, and 推延. To me, they all mean "to postpone, to delay". I was wondering if someone can provide accurate definitions for each, explain differences between the four terms, and provide example sentences.

an or bei I am having trouble distinguishing which preposition to use for sentences with schools as the object, like, "I am studying at Stanford University." Would it be, Ich studiere bei Stanford University, or Ich studiere an der Stanford University. I know that for general professional institutions, bei i normally used. However, for schools like universities, I have seen "an der Universitaet". So I am not so sure. An explanation and translation of the below examples would help a lot. Based on the correct grammar principle, how would you translate the following sentences: I am going now to Stanford University. We are studying German now at Stanford University. We are eating noodles at Stanford University. Are you studying French at Stanford University?
