Step 1: Understanding the Concept:
The objective of this question is to identify a synonym for the word "innocuous."
In English vocabulary, many words are derived from Latin roots that provide a clear indication of their meaning.
The word "innocuous" comes from the Latin "innocuus," which is a combination of "in-" (meaning not) and "nocuus" (meaning hurtful or injurious).
Therefore, the fundamental definition of the word revolves around the absence of harm or the lack of adverse effects.
Understanding such roots is a vital strategy for competitive exams like CUET.
Step 2: Detailed Explanation:
To find the word closest in meaning, we must perform a semantic analysis of the target word and each provided option.
1. Innocuous: This adjective is used to describe something that is not harmful or offensive.
It often describes things that might appear dangerous or significant but are actually quite safe.
Example: "While the spider looked menacing, the biologist assured us it was entirely innocuous."
It can also refer to remarks or jokes that are not intended to insult.
Example: "It was an innocuous comment, but he took great offense to it."
2. Evaluating the Options:
- Option (A) Harmful: This is a direct antonym. If something is harmful, it causes physical, emotional, or structural damage. Since we need a word "closest" in meaning, this is the opposite of what is required.
- Option (B) Harmless: This word is a perfect synonym. It literally means "without harm." It describes something that does not cause injury or ill effects. This aligns perfectly with the etymology of "innocuous."
- Option (C) Aggressive: This refers to a style of behavior or an attitude characterized by forcefulness or hostility. While an aggressive entity {might} be harmful, the word "aggressive" describes the {manner} of action, whereas "innocuous" describes the {result} or {nature} of the entity.
- Option (D) Suspicious: This refers to a feeling of doubt or a lack of trust. While someone might find an "innocuous" package to be "suspicious," the two words have entirely different definitions. Suspicion is a perception, while innocuousness is an inherent quality.
Detailed Contextual Comparison:
Consider a chemical substance. If the lab report says the substance is "innocuous," it means it will not react dangerously with your skin. This is exactly what we mean when we say it is "harmless." Therefore, the relationship is one of direct synonymy.
Step 3: Final Answer:
After analyzing the meanings, "Harmless" is the only word that mirrors the definition of "innocuous."
Thus, the correct choice is (B).
