What does worse mean?
Worse is the comparative form of bad and means lower in quality, less favorable, or more harmful. As an adjective, it describes a person, thing, or situation: a worse result, a worse alternative, or a worse condition. As an adverb, it compares two actions, conditions, or degrees: "He drives worse than he used to." The word is common across formal and informal English, although it is often more natural with than or a clear comparison such as "now" or "than before." Worse does not merely describe poor quality; it can also refer to increased danger, difficulty, failure, pain, or deterioration. The related verb worsen means to make or become worse, while the phrase "the worse for wear" describes something damaged or diminished through use. Together, these uses make worse essential for expressing comparisons involving bad conditions and for describing processes of decline.
