Human Readable is a term used in the context of Drupal CMS to describe a URL that is easy for a person to read and understand. It is also known as a "friendly URL" or "vanity URL". Human Readable URLs are typically shorter and more descriptive than the default URLs generated by Drupal. They are also easier to remember and share with others.

Human Readable URLs are created by using a combination of words and numbers that are meaningful to the user. For example, a URL for a blog post about Drupal might be "example.com/blog/drupal-cms". This URL is much easier to read and understand than the default URL generated by Drupal, which might look something like "example.com/node/12345".

Creating Human Readable URLs in Drupal is easy. All you need to do is enable the Pathauto module, which is part of the core Drupal installation. Once enabled, Pathauto will automatically generate Human Readable URLs for all content types. You can also customize the URLs to make them even more descriptive and easier to remember.

Human Readable URLs are an important part of any Drupal website. They make it easier for users to find and share content, and they also help with SEO by making it easier for search engines to index and rank your content.
