Which of the following prefixes means 'half'?

Rationale

Semi- means 'half'.

The prefix "semi-" is derived from Latin, directly translating to "half" and is commonly used in various terms to indicate a partial or half measure of something.

A (Anti-) YOUR ANSWER

The prefix "anti-" means "against" or "opposite." It is used to denote opposition or contrast to something, rather than indicating a fraction or division like "half." For example, "antibiotic" refers to a substance that works against bacteria, not implying any division.

B (Semi-) CORRECT

As previously stated, "semi-" means "half." It is used in words such as "semicircle," which refers to half of a circle, and "semiannual," indicating something occurring twice a year, or every half year. This prefix clearly conveys the concept of halving.

C (Inter-) YOUR ANSWER

The prefix "inter-" means "between" or "among." It is often used to describe interactions or connections between entities, such as in "international" (between nations) or "interstate" (between states). It does not signify a fraction or portion.

D (Non-) YOUR ANSWER

The prefix "non-" means "not" or "without." It is used to negate the meaning of the word it modifies, such as in "nonexistent" (not existing) or "nonprofit" (not aimed at profit). It does not relate to the concept of half in any way.

Conclusion

The prefix "semi-" is the only option that correctly conveys the meaning of "half," used to indicate partial measures or components. The other prefixes—anti-, inter-, and non-—each carry distinct meanings unrelated to division or fractions. Understanding these prefixes enhances comprehension in both language and terminology across various fields.
