The correct answer is: A. adamant
An antonym is a word that means the opposite of another word. In this case, the word “effete” means “weak, feeble, or exhausted.” The word “adamant” means “unyielding, firm, or resolute.” Therefore, the word “adamant” is the antonym of the word “effete.”
The word “adamant” comes from the Latin word “adamantÄs,” which means “unbreakable.” The word “adamant” is often used to describe someone who is determined or stubborn. For example, you might say that someone is “adamant in their beliefs” or that they are “adamant about getting their way.”
The word “effete” comes from the Latin word “effÄtus,” which means “worn out” or “exhausted.” The word “effete” is often used to describe someone who is weak or feeble. For example, you might say that someone is “effete in their old age” or that they are “effete after a long illness.”
The words “adamant” and “effete” are opposites in meaning. Someone who is adamant is determined and stubborn, while someone who is effete is weak and feeble.
