Antonyms

Fabulous means extraordinarily good, impressive, or luxurious - typically associated with wealth and richness. 'Poor' is the direct antonym as it represents the opposite economic condition. 'Rich' and 'luxury' are actually synonyms or related concepts, not antonyms. 'Prudence' is unrelated (it means wisdom in judgment).

Palatial means magnificent, grand, or resembling a palace (impressive in size or appearance). Unimpressive means ordinary or lacking impressive qualities. These words are direct opposites in meaning - palatial suggests grandeur while unimpressive suggests the opposite of grandeur.

Candid means frank, open, or straightforward in expression. Indirect means not straightforward or evasive in communication style. These words are opposites - a candid person speaks directly and honestly, while an indirect person avoids directness or clarity in communication.

Garble means to distort, confuse, or jumble something, especially speech or information. Misrepresent means to represent falsely or incorrectly. Both words convey the idea of presenting something in a distorted or wrong way, making them synonyms.

Nascent means just coming into existence, newly formed, or in an early stage of development. Moribund means in a dying state, near death, or stagnant. Since one refers to new birth and the other to approaching death, they are antonyms.

Voluble means talkative or excessively verbose, using many words. The correct antonyms are taciturn (reserved, uncommunicative) and untalkative. Chatty and garrulous are actually synonyms, not antonyms, so they're incorrect choices.

Loquacious means talkative or fond of talking. Option B (Taciturn) is its correct antonym, meaning reserved or silent. Nimble means quick, Trepid is not a standard word, and Platitude is a trite remark.

Garrulous means excessively talkative, especially on trivial matters. Reticent means not revealing one's thoughts or feelings readily, making it the direct antonym. Loquacious and gregarious are synonyms or related traits.

Lubricious can mean slippery, but in a behavioral context, it means lewd or wanton. Therefore, noble serves as a strong antonym. Vicious and lewd are closer to synonyms or unrelated, and tidy does not address the moral or physical connotations.

Indefatigable means persisting tirelessly. Irresolute means showing or feeling hesitancy or uncertainty, effectively serving as an antonym regarding persistence and determination. Dogged and inexhaustible are synonyms, while pellucid means clear.

Puissance means great power, influence, or prowess. While fragility is a physical weakness, lethargy (lack of energy/vigor) is often used as a conceptual opposite in standardized testing contexts. However, vigor is a synonym, making it incorrect as an antonym.

To grouse means to complain or grumble. The best antonym among the choices is compliment, which means to express praise. Exploit, legitimize, satiate, and compress do not represent the opposite of complaining.
