Understanding the Word "Mendacious"

The question asks for a synonym of the word "mendacious," which is used in the sentence: "Chuck is mendacious about his vegetarianism." To find the correct synonym, we first need to understand the meaning of "mendacious."

Analyzing the Options

Let's examine each option provided:

• Option 1: Untruthful

  This word means not telling the truth. It directly aligns with the meaning of "mendacious." Someone who is mendacious is, by definition, untruthful.

• Option 2: Proud

  This word means having or showing self-respect or pleasure derived from one's own achievements, qualities, or possessions. This is unrelated to the meaning of "mendacious."

• Option 3: Unhappy

  This word means not happy or sad. This emotion is entirely different from the characteristic of being dishonest or untruthful.

• Option 4: Clear

  This word can mean easy to perceive or understand, or free from ambiguity. It does not relate to telling lies or being untruthful.

Determining the Correct Synonym

Based on the definitions, "untruthful" is the only option that accurately reflects the meaning of "mendacious." Therefore, when the sentence states "Chuck is mendacious about his vegetarianism," it means Chuck is lying or being untruthful about whether he is a vegetarian.

The correct choice is the one that means untruthful.
