Hemi is a prefix that means what?

Hemi is a prefix that means what?

• A. Whole
• B. Below
• C. Above
• D. Half

Answer: (D)

Hemi- means half. In medical terms it shows one half of something, like a hemisphere (half of a sphere, such as the brain’s two halves) or hemiparesis (weakness on one side of the body). It comes from Greek and is used to indicate division into two equal parts. Other prefixes convey different ideas—whole is expressed with holo- or pan-, while below and above use hypo- or sub- and hyper- or supra-, respectively. So the correct meaning is half.
