In some English-speaking terms, close and shut and which refer to the same phrase, are sometimes used interchangeably with these two phrases.

If one were to replace shut with close in the expression “Shut up I’ll stand up! “, it would no longer retain its meaning and would only serve to confuse, although someone may find the alteration amusing, lessening the rudeness of the saying.

Since the act of closing and shutting would require the same operation and the state of being closed is nearly always identical to it being shut, you can feel confident using these as near perfect synonyms.

In an effort to distinguish between them, I will say that a thing that is closed brings to mind the idea that its contents are enclosed or inside. It also refers to hours of operation or availability, such as in “That shop is closing”, in a way that closed cannot express on its agr. An older phrase that encompasses the concept is “That shop is shut up for the day” (closed up works here even) or “that shops looks like it’s shut down”.

Difference happens when you get into the other definitions these words have and their differences happen how do you get them to work together properly but in a very similar way? People call themselves lovers. They like English because they have many definitions. One side effect is that by using words with different meanings, one is able to choose a word that has another meaning that also applies to the situation (sometimes this is where a connotation can come out). How do you know what synonym to use for a word it was used in in another context?

This are cases where the words retain the close/shut meaning, but where the meaning of the phrases they’re in are not identical:

close, shut; close up (temporary closing, in drawing – to bring lines together/close space), shut up (for the night ) (temporary closing and shelter & protection); close down, shut down (permanent closing, with shut down sounding more permanent); close the windows
