Plain answer
Enabling usually starts as love, fear, guilt, or crisis management. It becomes harmful when the family repeatedly softens reality, covers consequences, provides money or housing without accountability, or keeps the addiction system comfortable enough to continue. If you are asking what enabling means because the pattern is happening at home, the next step is not a bigger lecture. Name the rescue behavior, stop the help that is feeding active addiction, and get support for a boundary the family can actually hold.
