The prefix pseud(o) means which of the following?

• A. False
• B. True
• C. Mind
• D. Pus

Answer: (A)

The main idea is that pseud(o) signals something false or deceptive. It’s used to show that what follows imitates or pretends to be something it isn’t. For example, a pseudonym is a false name, and a pseudopod is a “false foot” of a cell. That makes the prefix a marker of falsehood or mimicry.

The other options don’t fit because they would require entirely different roots: mind would come from a prefix like psycho-; true would be conveyed by roots such as veri- or eu- in other contexts; and pus isn’t used as a prefix to mean a concept in medical terminology.
