Which suffix indicates a significant and persistent fear or aversion to something?

-scope
-itis
-phobia
-oma

The correct answer is: -phobia

The suffix that indicates a significant and persistent fear or aversion to something is indeed -phobia. This term derives from the Greek word "phobos," meaning fear or aversion. It is commonly used in psychology and medicine to describe conditions where individuals experience intense and irrational fear towards specific objects, situations, or activities. For example, acrophobia refers to the fear of heights, and claustrophobia refers to the fear of enclosed spaces. The use of this suffix effectively communicates the nature of the fear, characterizing it as not just a simple dislike but a profound and often debilitating response. The other suffixes mentioned have different meanings; -scope pertains to an instrument used for viewing or examining, -itis indicates inflammation, and -oma refers to a tumor or an abnormal growth.
