Never use abortion.
Don't use abort in content or user experiences for a general audience. If abort appears in a UI that you can't edit, use an alternative term to describe the customer action.
Use abort for a technical audience only if it's part of the application programming interface (API). Use an alternative term in comments and descriptions.
