What does the prefix "dys-" imply when used in a word?

The prefix "dys-" is derived from Greek, where it signifies something that is bad, impaired, abnormal, or difficult. This prefix is commonly found in various terms related to health and function, such as "dysfunction," which refers to an abnormal or impaired functioning. When "dys-" is attached to a root word, it usually conveys the notion of something that is not working properly or is problematic.

For example, in medical terminology, "dyslexia" refers to a learning disorder characterized by difficulties in reading, indicating an abnormality in reading skills. Therefore, the meaning of "dys-" aligns perfectly with the idea of something being negative or challenging, making this choice the most accurate representation of the prefix's meaning. Conversely, the other options suggest positive or neutral implications, which do not align with the established definition of "dys-."
