Step 1: Understanding the Concept:
Antonyms are words that exist at opposite ends of a semantic spectrum.
Identifying an antonym requires a deep understanding of the word's primary definition, its secondary connotations, and the specific behavioral or physical trait it describes.
The word in question, \(reticent\), is an adjective primarily used to describe a personality trait or a temporary state of communication.
In competitive examinations like CUET, vocabulary assessment often focuses on words that have nuanced meanings related to human temperament.
The core concept here is the "volume and willingness of communication."
Step 2: Detailed Explanation:
Let us conduct an exhaustive analysis of the word \(reticent\).
The term is derived from the Latin word \(reticere\), where 're-' is an intensive prefix and 'tacere' means "to be silent."
Strictly speaking, someone who is reticent is not just "quiet"; they are someone who is inclined to be silent or uncommunicative in speech.
They are reserved, specifically regarding their thoughts, feelings, or personal information.
Example: "The witness remained reticent throughout the interrogation, refusing to provide any details about the incident."
Now, let us scrutinize each option provided to determine the exact semantic opposite:
1. Hostile: This adjective refers to an unfriendly, antagonistic, or aggressive state.
While a reticent person might appear unfriendly due to their lack of speech, \(hostile\) describes a state of conflict or enmity rather than the frequency of words spoken.
Being hostile is not the opposite of being quiet; one can be both loud and hostile or quiet and hostile.
2. Talkative: This is the direct behavioral opposite of being reticent.
A talkative person is loquacious, garrulous, or communicative. They enjoy the act of speaking and share thoughts freely.
Where a reticent person holds back, a talkative person lets flow.
This matches the exact opposite semantic value required for an antonym.
3. Controversial: This refers to something that provokes public disagreement or heated discussion.
This describes the nature of a topic or a person's public standing, not their communicative habit.
A reticent person can be involved in a controversy, but the words are not opposites.
4. Aggressive: This describes a person ready to attack or confront, or someone pursuing goals with force.
While aggression can be verbal, the opposite of \(reticent\) is about the quantity and openness of speech, not the force behind it.
Step 3: Final Answer:
The most appropriate antonym for \(Reticent\) is \(Talkative\), which corresponds to option (b).
