The word part placed before a word to change its meaning is called?
Correct Answer: B
Rationale: The correct answer is B: Prefix. A prefix is a word part placed before a word to change its meaning. For example, in the word "unhappy," "un-" is the prefix that changes the meaning of "happy."
Rationale:
1. Suffixes are word parts placed after a word, not before, to change its meaning.
2. Afflix is not a standard term in linguistics; the correct term is affix, which includes both prefixes and suffixes.
3. Vocabulary refers to a collection of words known or used by a person, not a word part placed before another word.
In summary, the prefix is the correct term for a word part placed before a word to alter its meaning, making choices A, C, and D incorrect in this context.
