Comments are a feature of blogs which allow readers to respond to Posts. Typically, readers simply provide their own thoughts regarding the content of the post, but they may also provide links to other resources, generate discussion, or simply compliment the author for a well-written post. Comments allow you to interact more with your site visitors as well as generate feedback and discussion on your Posts.
Comments can be controlled and regulated through the use of filters for language and content, and if you prefer, can also be queued for approval before they are visible on the web site. This is useful in dealing with comment spam (https://codex.wordpress.org/Comment_Spam).
When you click on the Comments menu option, you’ll be shown a list of all the comments on your site.
