Pairs of Words — The Confusables Every CSS Candidate Must Know
The Pairs of Words question (10 marks) asks you to write sentences that distinguish two similar-sounding or similar-looking words. The trap is not that the words are rare — most are common — but that their meanings are easy to slip up on under time pressure.
A CSS question that supplies a list of word pairs (usually five) and asks the candidate to use each pair in distinct sentences that demonstrate the difference in meaning. Two marks per pair; ten marks total.
How the question is set
"Use each pair of the following words in your own sentences to bring out their meaning. Do not change the form of the words."
(a) affect — effect (b) principal — principle (c) complement — compliment (d) stationary — stationery (e) elicit — illicit
You write two short, distinct sentences for each pair — one for each word. The sentences must clearly distinguish meaning, not merely use the words.

- For exam answers, write two SHORT sentences — one per word — that clearly establish the meaning.
- Don't write essays. Two crisp sentences earn full marks; long passages risk error.
- Always check the part of speech. Advise is a verb; advice is a noun. Confuse these and you'll get a wrong-sounding sentence.
- Some confusables (assure/ensure/insure, cite/site/sight) come in groups of three. Memorise them as a set.
Sample answer — well-written response
Suppose the pair is affect — effect. Here is a good and a poor response.
Poor:
His decision had an effect that affected everyone, and the effect was felt by all who were affected.
The candidate uses both words but doesn't draw out the distinction.
Good:
(a) Climate change has begun to affect wheat yields in central Punjab. (b) The cumulative effect of three poor harvests is now visible in food prices.
Each sentence uses one word; the grammatical role (verb vs noun) makes the distinction explicit; the context is realistic.
One useful memory trick
For affect / effect, remember RAVEN:
- R Remember
- A Affect is a
- V Verb
- E Effect is a
- N Noun
For principal / principle, remember that the school principal is your pal.
For stationary / stationery, remember that stationary (a for at rest) is not moving; stationery (e for envelope) is writing material.
