"Everything" implies absolute completeness. It refers to every single thing that exists, without exception. It encompasses all things, ideas, concepts, and even non-physical entities.
* Example: "Everything in the universe is made of atoms."
"All" is more inclusive, but it doesn't always mean absolute completeness. It can refer to a specific group or category, and it can be used with qualifications.
* Example: "All cats are mammals." (Here, "all" refers to the specific category of cats.)
* Example: "All the books on the shelf are fiction." (Here, "all" refers to a specific group of books, those on the shelf.)
In summary:
* Everything is a universal and absolute term.
* All is more specific and can be used with qualifications.
Here are some additional examples to illustrate the difference:
* Everything is made of matter and energy.
* All my friends live in the same city.
* Everything that happens has a cause.
* All the students passed the test.
In most cases, "everything" and "all" can be used interchangeably. However, when you want to emphasize absolute completeness, "everything" is the more appropriate choice.
