Which prefix means 'Half'?

Which prefix means 'Half'?

• A. Intra
• B. Epi
• C. Exo
• D. Iso

Answer: (C)

Half is expressed with hemi- or semi-. Hemisphere, hemiparesis, semicircle, and semipermeable are all examples where half is the idea being conveyed. The prefixes shown here have different meanings: intra- means within, epi- means upon or on, exo- means outside, and iso- means equal or same. So none of these indicate half; when you need to show half, use hemi- or semi- to modify the root.
