Difficulty: MediumAntonyms and Words Opposite in Meaning

Match each of the following vocabulary words in the left column with its precise antonym (word opposite in meaning) in the right column.

  • MercurialSteadfast
  • InsouciantConcerned
  • ObsequiousAssertive
  • InchoateFully formed

Answer

Mercurial matches with Steadfast, Insouciant matches with Concerned, Obsequious matches with Assertive, and Inchoate matches with Fully formed.
The pairing correctly matches each term with its exact opposite in meaning: 'Mercurial' (volatile) contrasts with 'Steadfast' (constant); 'Insouciant' (unconcerned) contrasts with 'Concerned'; 'Obsequious' (servile) contrasts with 'Assertive'; and 'Inchoate' (undeveloped) contrasts with 'Fully formed'.

Step-by-Step Solution

1
Analyze the meaning of each vocabulary word in the left column.
'Mercurial' denotes volatility/unpredictability; 'Insouciant' denotes unconcerned indifference; 'Obsequious' denotes servile submissiveness; 'Inchoate' denotes an embryonic or undeveloped state.
Establishing clear semantic definitions is required before finding exact antonyms.
2
Evaluate the terms in the right column to find the precise opposite of each left-column word.
'Steadfast' directly opposes 'Mercurial'; 'Concerned' directly opposes 'Insouciant'; 'Assertive' directly opposes 'Obsequious'; 'Fully formed' directly opposes 'Inchoate'.
Antonyms express directly contrasting attributes along the same semantic domain.
