Step 1: Understanding the Concept:
"Ephemeral" is a high-level vocabulary word often found in literature and academic English.
It refers to something that is very short-lived or lasts for only a fleeting moment.
The word originated from the Greek 'ephēmeros,' which literally translates to "lasting only a day." It was originally used in biology to describe insects (like mayflies) that have a very short lifespan.
Step 2: Detailed Explanation:
To find the synonym, we must identify a word that denotes a short duration of time.
1. Word Analysis of the Options:
(C) Transient: This is the correct synonym. 'Transient' describes a state or condition that is temporary or staying for only a short time. For instance, the "transient beauty of a rainbow" perfectly mirrors the "ephemeral nature of a sunset." Both imply that the thing will soon vanish.
(A) Permanent: This is a direct antonym. Permanent means lasting or intended to last or remain unchanged indefinitely.
(B) Eternal: This is an antonym. Eternal means lasting or existing forever; without end or beginning.
(D) Lasting: This is also an antonym. It refers to something that continues for a long time (e.g., a lasting impression).
2. Why Ephemeral is important in exams:
Examiners love this word because it sounds complex, but its meaning is simple: "short." It is often grouped with words like "fleeting," "momentary," "evanescent," and "fugacious."
3. Contextual Examples:
- "Social media fame is often ephemeral; you are a star one day and forgotten the next."
- "The ephemeral joy of a summer holiday ends all too soon."
Step 3: Final Answer:
Because "Ephemeral" and "Transient" both describe things that do not last long, they are synonyms. Thus, Option (C) is the correct answer.
