Anything is a word used to describe any event, act, fact, or object that has the potential of becoming or being something. People use the word “anything” for something that is present or has the potential of becoming a reality.
At times, it can be used as an indefinite pronoun to replace a noun. “Anything” can be used to describe something important. On the other hand, the word “nothing” means an absence of anything or a lack of anything. For instance, it has the connotations of darkness, a vacuum, and empty space.
At times, people use it to describe events or things that are unimportant. You can use ‘nothing’ to describe things that do not exist. Like “anything,” the word “nothing” can also be used as an indefinite pronoun. Some people argued that the word “nothing” must not be used to function as a noun since it describes the absence of anything.
