The prefix EX- denotes which meaning?

The prefix EX- denotes which meaning?

• A. Without
• B. With
• C. Inside
• D. Across

Answer: (A)

EX- in medical terms signals movement outward, away from a location, which carries the sense of removal or absence. That outward sense lines up with interpreting the meaning as “without” in the sense of taking something away or being lacking inside. For example, exhale means to breathe out, and excretion is the act of removing waste from the body. Among the options, “without” best captures that idea of something being outward or lacking from within. The other directions don’t fit as well: “with” implies inclusion, “inside” is the opposite, and “across” doesn’t convey the idea of moving out or removing.
