Tacit Enabler - Supports anothers bad habits by staying silent.

Overt Enabler - Supports anothers bad habits by providing assistance such as money, transportation, approval, etc...

A person who supports another persons bad or dangerous habits.
Enablers tend to fear calling others on their destructive habits because these others tend to be friends, family or others close to the enabler.
Thus, rather than risk losing the love, respect, friendship or contact with the person, the enabler chooses instead to play it safe and watch the other slowly destroy themselves or others through their own actions.
