Which expression was chosen as the Hindi Word of the Year 2018 by Oxford Dictionaries?

Introduction / Context:
Oxford Dictionaries selects a Hindi Word of the Year to reflect social, cultural, and political trends in India. For 2018, the chosen expression highlighted the growing focus on women's empowerment and their role in society. Exam questions often refer to this selection because it links language, social change, and current affairs in an easily testable fact.

Given Data / Assumptions:

• The selection is the Hindi Word of the Year 2018 by Oxford Dictionaries.
• Four possible words or phrases are given: Nari Shakti, Aadhaar, Samvidhaan, and Swachh Bharat.
• Only one of these was chosen for the year 2018.
• We assume that the candidate is aware of the sequence of Hindi Words of the Year.

Concept / Approach:
The key idea is that the Hindi Word of the Year reflects issues that dominated public discussion during that year. In 2018, debates around women's rights, representation, and safety were very prominent, supported by movements and government programmes. As a result, Oxford Dictionaries selected “Nari Shakti”, meaning “women power”, as the Hindi Word of the Year 2018. Aadhaar and Samvidhaan were chosen for other years, and Swachh Bharat is a different government campaign slogan. The approach is to correctly match 2018 with “Nari Shakti”.

Step-by-Step Solution:
Step 1: Note that the year in the question is specifically 2018. Step 2: Recall that “Nari Shakti” was widely discussed at that time and was selected by Oxford Dictionaries as the Hindi Word of the Year 2018. Step 3: Look at the options and find “Nari Shakti” as Option A. Step 4: Recognise that “Aadhaar” had been chosen as the first Hindi Word of the Year earlier, and “Samvidhaan” belongs to another year. Step 5: Mark “Nari Shakti” as the correct answer.

Verification / Alternative check:
A useful check is to align each word with its associated theme. “Nari Shakti” relates to women empowerment, which dominated 2018 discourse. “Aadhaar” is linked to identity and digital governance debates in an earlier period, and “Samvidhaan” reflects constitutional issues in a later year. “Swachh Bharat” is the name of a flagship cleanliness campaign, but it was not designated as the Hindi Word of the Year 2018 by Oxford Dictionaries. This thematic mapping confirms that Option A is correct.

Why Other Options Are Wrong:
Aadhaar: This term was indeed a Hindi Word of the Year, but it was chosen for an earlier year, not for 2018, so it does not answer the question asked.
Samvidhaan: Associated with constitutional debates and chosen as a Hindi Word of the Year for a different year, not 2018, making this option incorrect here.
Swachh Bharat: A central government campaign for cleanliness, but it was not selected as the Hindi Word of the Year 2018 by Oxford Dictionaries.

Common Pitfalls:
One common mistake is confusing the timeline of Hindi Word of the Year announcements and mixing up which word belongs to which year. Another pitfall is focusing only on familiarity with government schemes like Swachh Bharat rather than the specific Oxford Dictionaries selection. Maintaining a simple chronological list of important “Word of the Year” announcements can help you avoid such errors in exams.

Final Answer:
Nari Shakti
