Which prefix refers to 'half' or 'partial'?

The prefix that refers to 'half' or 'partial' is "Hemi." This prefix is derived from the Greek word "hēmi-" meaning half. It is often used in various contexts, such as in the term "hemisphere," which refers to half of a spherical object, typically the Earth. Understanding this prefix is important for recognizing its application in both medical and scientific terminology, where it can describe structures or conditions that are halved or partially represented.

The other prefixes do not convey the meaning of 'half' or 'partial.' For instance, "Hypo" generally means below or under, indicating a deficiency or lower state. "Ana" denotes upward movement or again indicates increase, while "Neo" refers to something new or recent. Thus, "Hemi" is the appropriate choice for denoting 'half' or 'partial.'
