It is obvious that shut and close are very similar in meaning. However, while learning English as non-native (a long time ago) the teacher underlined that the two words are not identical in meaning.
I was unable to find a "clear" explanation about this difference yet - so I am still confused.
- the definitions of the words;
- how the words are similar;
I did not find: how are these words different.
Edit: Based on the answers and on the comments, is it safe to assume that there is no "general" rule about when to use "shut" and "close"? And that one must learn the "correct" verb for each situation separately?
