Hi @shawn Jones ,

Welcome to Atlassian community.

In addition to what explaines by @Trudy Claspill , for the standard issue link type there is an usual meaning. You can find an explanation in a Deviniti article: https://deviniti.com/blog/enterprise-software/jira-linked-issues-templates/#:~:text=1.,them%20needs%20to%20be%20addressed. 

Kind regards

Hello @shawn Jones 

Your company (or the users/administrators of your Jira instance) get to define what those represent.

Some link types are provided by default by Jira out of the box, like Relates, Blocks, and Clones.

Others may be added by the Jira Admins or third party apps to help identify the relationship between items.
