What does the prefix '-phil' indicate?

The prefix '-phil' is derived from the Greek word "philos," which means "loving" or "fond of." Therefore, when this prefix is used in medical terminology, it indicates attraction or affinity toward a particular substance or condition. For example, in terms like "hydrophilic," it refers to a substance that is attracted to water. This shows that the presence of the prefix involves a positive relationship or affinity rather than a neutral or negative one.

In contrast, the other options suggest a lack of attraction or a negative response to something. Repulsion, indifference, or aversion would imply a distance or absence of connection, which is contrary to what '-phil' represents. Thus, the correct answer highlights the concept of attraction or a favorable inclination toward something, aligning perfectly with the meaning of the prefix.
