In the UPSC CDS English paper, the “Usage of Paired Words” (Homophones and confusable words) is asked regularly. Confusing two similar-sounding words can change the meaning of an entire order, which is exactly why the UPSC loves this section.
These questions give you a pair of words that sound almost identical but have completely different spellings and meanings. Your job is to identify the correct word based on the sentence’s context.

1. Most Important “Trap Pairs”

Affect vs. Effect
Affect (Verb): To influence or produce a change. (e.g., The weather will affect our travel plans.)
Effect (Noun): The result or outcome of a change. (e.g., The new policy had a positive effect on the troops.)
Compliment vs. Complement
Compliment: An expression of praise or admiration. (e.g., He paid her a lovely compliment on her speech.)
Complement: Something that completes or brings to perfection. (e.g., Spicy pickles complement a simple meal perfectly.)
Eminent vs. Imminent
Eminent: Famous, respected, or prominent. (e.g., An eminent scientist addressed the cadets.)
Imminent: About to happen at any moment. (e.g., The dark clouds suggest that rain is imminent.)
Stationary vs. Stationery
Stationary: Not moving; fixed in one place. (e.g., The truck hit a stationary car.)
Stationery: Writing materials like pens, paper, and envelopes. (e.g., I need to buy some official stationery.)

Common MistakesÂ
CDS aspirants often make these mistakes in the exam:
- Memorising Without Context (They memorise meanings of the words but fail to apply them in sentences)
- Ignoring Parts of Speech (Understanding whether the blank requires a noun, verb, or adjective is important)
- Relying Only on Pronunciation (Words may sound similar but differ completely in meaning and spelling)
Quick Tips to Master Paired Words
- Read English newspapers daily.
- Learn words as used in sentences.
- Take notes of confusing word pairs and revise weekly.
- Practice the previous years’ CDS English papers.
- Focus on sentence context. Don’t just memorise isolated words.
