What is the meaning of "dys-" when used as a prefix?

1. Normal

2. Bad

3. Above

4. Separation

The correct answer is: Bad

The prefix "dys-" is derived from Greek, and it signifies something that is difficult, bad, or abnormal. When attached to a word, it indicates a negative or undesirable condition related to that word's meaning. For example, in medical terminology, "dysfunction" refers to the abnormal or impaired functioning of a particular body part or system. In contrast, the other choices represent meanings that do not align with the definition of "dys-." The prefix indicating something normal or healthy would be "eu-," while "above" would typically relate to prefixes like "hyper-." The concept of separation is encompassed by prefixes such as "dis-." Therefore, when considering the meaning of "dys-" as related to negative conditions or abnormalities, "bad" is the accurate interpretation.
