WordPress Templates fit together like the pieces of a puzzle to generate the web pages on your WordPress site. Some templates (the header and footer template files for example) are used on all the web pages, while others are used only under specific conditions.
WordPress can hold and display many different types of content. A single item of such a content is generally called a post, although post is also a specific post type. Internally, all the post types are stored in the same place, in the wp_posts database table, but are differentiated by a column called post_typ
Taxonomy is one of those words that most people never hear or use. Basically, a taxonomy is a way to group things together. For example, I might have a bunch of different types of animals. I can group them together according to various characteristics and then assign those groups names. This is something most people encounter in biology classes, and it is known as the Linnaean Taxonomy. In WordPress, a “taxonomy” is a grouping mechanism for some posts (or links or custom post types). The names for the different groupings in a taxonomy are called terms. Using groupings of animals as an example, we might call one group “birds”, and another group “fish”. “Fish” and “birds” are terms in our taxonomy. As an example from WordPress, a category or tag (see next section) is a term.
