SSC One-Word Substitution is one of the highest-scoring topics in the English section of SSC CGL, SSC CHSL, SSC MTS, SSC GD, RRB, Banking, Insurance, Defence, and other competitive examinations. One-word substitution questions are frequently asked in SSC and other competitive examinations. Learning these words along with their Hindi meanings and easy memory tricks will improve both your vocabulary and exam performance.
What is One-Word Substitution ?
A One-Word Substitution is a single word that replaces a group of words or a complete definition while conveying the same meaning.
Example: A life story written by oneself → Autobiography
How to Solve One-Word Substitution Questions:
- Read the definition carefully and identify the key idea (person, place, animal, or action).
- Eliminate options that are close in spelling but wrong in meaning (e.g., Astrologer vs Astronomer).
- Break the word into its root (like “Omni-“, “Somn-“, “-phile”) to guess the meaning if you don’t know the word directly.
- If unsure, choose the option that matches the definition most precisely, not just partially.
