Category is one of the pre-defined taxonomies in WordPress. It is used to sort and group content into different sections. A website publishing content on a variety of topics can divide their website into sections using categories.
Example: A news website can have categories for articles filed under News, Opinion, Weather, Sports, etc.
(Think of Categories as your “Chapters” on your blog)
