Someone characterized by habitual drunkenness—a drunkard. Paul lists this vice twice in 1 Corinthians 5-6, alongside sexually immoral, greedy, and verbally abusive people. Like 'reviler,' this describes a pattern, not a single incident. Such people aren't to be tolerated in church fellowship and won't inherit God's kingdom. The classical Greek form was originally feminine ('drunken Amazon'), later extending to males. The emphasis is on intemperance as a lifestyle, not occasional overindulgence.
