Which of the following words is the antonym of "transparent"?

Appeared in: NORCET 9 Prelims-2025

Explanation

An antonym is a word that has the opposite meaning of another word.
The word 'transparent' means allowing light to pass through completely, so that objects on the other side are clearly visible.
'Opaque' means not allowing any light to pass through, which is the direct opposite of 'transparent'.

Option A: 'Clear' is a synonym for 'transparent', not an antonym. It describes something that is easy to see through.
Option C: 'Translucent' describes something that allows some, but not all, light to pass through, and does not allow for clear viewing of objects. It represents a state between transparent and opaque, not a direct opposite.
Option D: 'Lucid' is a synonym for 'transparent', particularly in the context of being clearly expressed or easy to understand.

Visual 1: Infographic - An image demonstrating how light rays interact with transparent, translucent, and opaque materials. This visual would show light passing straight through the transparent object, scattering as it passes through the translucent object, and being blocked by the opaque object.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Vocabulary: Antonyms as background academic context rather than a clinical decision trigger.
In pharmacology, understanding material properties is crucial. Many medications (e.g., nitroglycerin, furosemide, amphotericin B) are light-sensitive and must be stored in opaque containers or packaging to prevent chemical degradation and maintain their potency.
In radiology, body tissues have different levels of opacity to X-rays. Bone is opaque, while soft tissues are more translucent, allowing for diagnostic imaging.
What if? If a light-sensitive medication was mistakenly stored in a transparent or even translucent container, it would likely lose its effectiveness due to photodegradation. This could lead to treatment failure and adverse patient outcomes.

How to Approach the Question

First, identify the core meaning of the word in the question stem. 'Transparent' means 'see-through' or 'clear'.
Next, understand the task. The question asks for an 'antonym,' which is a word with the opposite meaning.
Evaluate each option to find the one that means the opposite of 'transparent'.
Analyze the distractors: 'Clear' and 'Lucid' are synonyms. 'Translucent' means 'partially see-through,' which is related but not the direct opposite.
Identify the correct antonym: 'Opaque' means 'not see-through,' making it the direct opposite of 'transparent'.
