Which term corresponds to 'Prefixes indicating negation or absence'?

• A. Negative Prefixes
• B. Prefixes
• C. Red Letter Day
• D. Idiom

Answer: (A)

Negation in word formation is shown by prefixes that express not or the opposite of the base meaning. The term for these is negative prefixes. They attach to base words to convey absence or opposite meaning, like un- in unhappy or in- in impossible. That specificity is what makes it the best fit for the prompt about “Prefixes indicating negation or absence.” In contrast, simply calling them prefixes is too broad and wouldn’t focus on the negation aspect. An idiom or “red letter day” belongs to a different area of language—phrases with figurative meaning rather than a grammatical category of prefixes. So the correct term is negative prefixes.
