The word everything functions as a pronoun.
To understand why, let’s break it down. A pronoun is a word that can replace a noun or noun phrase, often to avoid repetition or to generalize. In this case, everything refers to all things or all that exists, acting as a substitute for a more specific noun.
For example, in the sentence, ‘Everything is on the table,’ everything stands in for all items or objects, encapsulating them within a single term. Thus, it serves the role of a pronoun in this context. Understanding the part of speech for words can significantly help in constructing clear and effective sentences in our writing.
