Which two prefixes have a similar meaning in medical terminology?

The prefixes "poly-" and "multi-" both indicate a quantity greater than one, referring to multiple elements or instances. In medical terminology, "poly-" often describes conditions or parameters that involve several parts or excessive amounts, such as "polyuria" (excessive urination) or "polydipsia" (excessive thirst). Similarly, "multi-" refers to many or several, as seen in terms like "multisystem" or "multipara," which denotes a woman who has given birth multiple times.

This shared connotation of indicating multiplicity makes "poly-" and "multi-" comparable in meaning. Other prefixes listed do not share this specific characteristic; for instance, "mono-" and "uni-" mean one, while "hemo-" and "sanguin-" refer to blood, and "hyper-" and "hypo-" refer to excessive and below normal levels, respectively. Hence, "poly-" and "multi-" are the correct pair of prefixes with similar meanings in the context of medical terminology.
