One‑Word Substitution – Study Notes
Exam: Himachal Pradesh Forest Guard
Section: English Language – One‑Word Substitution
These notes give you a clear, concise guide to tackle the one‑word substitution type of questions in the exam.
1. Simple Explanation
One‑word substitution asks you to replace a word in a sentence with another single word that has the same meaning (synonym) without changing the grammatical structure or the overall sense of the sentence.
“The teacher was very pleased with the students’ effort.”
Replace pleased → satisfied
Key points:
- Replacement word must fit the grammatical role (noun → noun, verb → verb, etc.).
- The meaning of the entire sentence should stay the same.
- The answer is always one word (no phrases or clauses).
2. Key Points & Strategy
| # | Point | Why it matters | Quick Tip |
|---|---|---|---|
| 1 | Identify the target word | You can’t change the wrong word. | Look for underlined or bold words. |
| 2 | Know the part of speech | A noun can’t be replaced by a verb. | Check the word’s function in the sentence. |
| 3 | Find synonyms | Core of the test. | Use a thesaurus or mental list. |
| 4 | Check context | Some synonyms fit only in specific contexts. | Read the whole sentence. |
| 5 | Check grammar | Replacement must not alter tense, number, or case. | Ensure subject–verb agreement, correct prepositions. |
| 6 | Avoid antonyms or unrelated words | They’ll change the meaning. | Look for words that convey the same idea. |
| 7 | Eliminate obviously wrong options | Saves time. | Discard words that clash with context or grammar. |
| 8 | Confirm the answer in all options | One option will fit best. | Compare each option against the sentence. |
Common Synonym Pitfalls
| Target Word | Wrong Choice | Reason |
|---|---|---|
| Happy | “Sad” | Opposite meaning |
| Quick | “Slow” | Opposite meaning |

| Begin | “End” | Opposite action |
| Large | “Tiny” | Opposite size |
