What is a Slug?
A slug within web terms can be defined as the editable part of the URL. The slug is located at the end of the url after the base domain prefix and often contains relevant keywords with hyphen separators. Permalink structures can also influence the slug by including date, time, author, post id, etc. which can be changed via Settings. By default the slug takes the title of the page or post, however this can be changed. Think about the slug as a customizable address of the page and that users can edit the hyperlink/location of the page.
