Which prefix means Half?

Which prefix means Half?

• A. Exo
• B. Iso
• C. Inter
• D. Epi

Answer: (A)

Prefixes in medical terms tell you about location or relation. When you think of half, the terms you’d expect are semi- or hemi-. They convey a division into two equal parts. In the given options, exo- means outside or external, as in exoskeleton. Iso- means equal or the same, as in isometric. Inter- means between or among, as in intercellular. Epi- means upon, on, or above, as in epidermis. None of these means half, so half is not represented among the choices.
