Here's a breakdown:
* Noun: A word that names a person, place, thing, or idea. (Example: *cat*, *house*, *love*)
* Pronoun: A word that stands in for a noun, avoiding repetition. (Example: *it*, *he*, *she*, *they*, *we*, *you*, *I*).
Example:
* "The cat sat on the mat." (The noun "cat" is the subject of the sentence.)
* "It sat on the mat." (The pronoun "it" replaces the noun "cat".)
Pronouns help to make our writing smoother and more concise by avoiding unnecessary repetition of nouns.
