What does the prefix "hypo" indicate?

The prefix "hypo" originates from Greek, where it means "under" or "below." In a variety of contexts, particularly in medical terminology, it indicates a condition of deficiency or a lower level of something. For example, in the term "hypoglycemia," it describes a state where there is a deficiency of glucose in the blood. This understanding makes it clear why "below" or "deficient" accurately represents the meaning of "hypo."

The other options suggest different meanings that do not align with the original Greek intent. "Above" refers to the opposite notion, while "scanty" or "little" suggests something about quantity, which may not necessarily convey the idea of being below or deficient. The term "between" also does not accurately capture the essence of deficiency or a lower state, instead suggesting a position rather than a deficiency or lack. Thus, "hypo" effectively indicates a below-normal or deficient condition.
