What is a parameter?

If you’re averse to learning new terms, you can think of the term parameter as a synonym of attribute. When you’re writing markup, the general syntax used for a parameter will look just like the syntax used for an attribute.

That being said, in the L&L documentation and in advanced WordPress development in general, you’ll find that when we refer to the attributes of a query (such as the attributes of the <Loop> tag), we call those query parameters because that’s a common term used to refer to the internal working of WordPress’s loop query. In contrast, other dynamic tags that don’t create queries (such as the <Field /> tag) simply use the term attribute just like normal HTML syntax.
