Disqualify → It is formed from "dis-" (meaning apart or away) and "qualis" (meaning of what kind or quality). The word "disqualify" means to take away someone's qualification or to declare them unfit for a certain role or task.
Think of being 'taken away' ('dis-') from a certain 'quality' ('qualis') — that's why disqualify means to remove someone's eligibility.
