Paired Words — Homonyms and Homophones
~12 min read
- What: Paired Words tests pairs of words that look alike, sound alike, or are spelled alike but mean different things. The block covers paronyms (similar spelling), homonyms (same spelling), and homophones (same sound).
- Why it matters: NDA does not always carry a dedicated Paired Words block, but the same discrimination is tested heavily inside Fill in the Blanks, Spotting Errors, and Sentence Improvement. Confusable-pair mastery is exam-wide.
- Key habit: Build a personal confusables list and revise it weekly. Eighty pairs covers ~95% of what NDA will test, directly or indirectly.
English is unusual among major world languages in the density of confusables it carries — pairs like affect/effect, principal/principle, compliment/complement. The Bakshi syllabus calls this topic "Paronyms and Homonyms"; NDA's question pool weaves it through several blocks rather than testing it as a standalone section. Either way, the skill is the same: tell two near-identical words apart and pick the one that fits.
This page consolidates the three confusable families, the discrimination method, and an 80-pair high-frequency bank drawn from NDA-style usage. Pair this page with Synonyms (vocabulary base), Spotting Errors (where confusables hide), and Fill in the Blanks (where confusables are the test).
What This Topic Covers
NDA Pairs — Where Confusables Get Tested
- Dedicated block (occasional): Some NDA papers have a "Pairs / Confusables" sub-block of 3–5 items, asking which option uses the correct word from a pair.
- Embedded in Spotting Errors: An error sentence will use the wrong member of a pair (affect where effect belongs).
- Embedded in Sentence Improvement: The "better substitution" replaces a confusable with its partner.
- Embedded in Fill in the Blanks: The blank tests whether you can pick the right confusable.
Three Families — Paronyms, Homonyms, Homophones
Distinguish the three families because the trap mechanism differs.
Family 1 — Paronyms (look alike, sound alike, different meanings)
Both words come from the same root but have drifted to different meanings. economic/economical; historic/historical; literate/literal; sensual/sensuous; fictitious/fictional.
Example: "She made an economical use of resources." (= thrifty.) "The 2008 economic crisis." (= relating to the economy.)
Family 2 — Homonyms (same spelling and sound, different meaning)
One word, multiple unrelated meanings. bank (river / financial); bat (cricket / animal); spring (season / coil / leap / water source); match (game / pair / firestick).
Example: "He sat on the bank of the river." vs. "He works at a bank." Same word, two senses — context decides.
Family 3 — Homophones (same sound, different spelling and meaning)
Sound alike, spell differently. their/there/they're; here/hear; pair/pear/pare; cite/site/sight; principal/principle; stationary/stationery.
Example: "The principal reason for the delay." (= main.) "It is against my principles." (= moral rules.) Sound identical; spelling and meaning differ.
The Three-Question Method
When you see a confusable in an NDA item, ask three questions in order:
- Part of speech? Many confusable pairs split by part of speech. Advise (verb) / advice (noun). Practise (verb, BrE) / practice (noun, BrE). Effect (verb = bring about / noun = result) / affect (verb = influence / noun = mood). Knowing this kills half the confusable items.
- Which sense fits the sentence? If both words are the right part of speech, the meaning decides. Comprehensive (covering all parts) vs comprehensible (understandable). Practical (real-world useful) vs practicable (capable of being done).
- If still stuck, default to the more formal of the two. In NDA's exam register, the slightly more formal word is more often the answer. Among vs amongst — both correct; among is more common in exam-style English.
The 80% Rule
- POS first. Part of speech rules out ~50% of confusable pairs immediately.
- Sense second. Among same-POS pairs, sense rules out ~30% more.
- Default last. The remaining ~20% are tie-broken by formality or by the slightly more frequent NDA usage.
Worked Examples
Worked Example 1 — affect vs effect
Stem: The new policy will _____ thousands of farmers.
Options: (a) affect (b) effect (c) effort (d) afflict
Q1 — POS: We need a verb (after "will"). Affect is a verb (= influence). Effect is usually a noun (= result), occasionally a verb (= bring about, formal).
Q2 — Sense: "Influence" fits the policy / farmers context.
Answer: (a) affect.
Trap-pair memo: "Affect = Action verb; Effect = End-result noun." Most of the time, this binary holds.
Worked Example 2 — principal vs principle
Stem: Honesty is one of his guiding _____.
Options: (a) principals (b) principles (c) principalities (d) principal
Q1 — POS: We need a noun, plural.
Q2 — Sense: "Guiding" suggests moral rules. Principle = a fundamental rule or moral. Principal = head of a school / chief.
Answer: (b) principles.
Memory trick: The principal is your "pal" — a person. A principle is a rule.
Worked Example 3 — compliment vs complement
Stem: Her scarf perfectly _____s her dress.
Options: (a) compliments (b) complements (c) compliances (d) implements
Q2 — Sense: "Perfectly matches / completes" the dress. Complement = complete or match. Compliment = praise.
Answer: (b) complements.
Memory trick: Compliment = "I" praise you. Complement = "Le"vels up / completes the look.
Worked Example 4 — stationary vs stationery
Stem: The car remained _____ at the signal.
Options: (a) stationery (b) stationary (c) station (d) statuesque
Q2 — Sense: Not moving. Stationary = not moving. Stationery = pens, paper, office supplies.
Answer: (b) stationary.
Memory trick: Stationary = at rest (think "at a halt"). Stationery = "envelopes, erasers".
Worked Example 5 — economic vs economical
Stem: She is _____ in her use of resources.
Options: (a) economic (b) economical (c) economics (d) economy
Q2 — Sense: "Thrifty" is the right idea. Economical = thrifty, avoiding waste. Economic = relating to the economy.
Answer: (b) economical.
Lesson: The -ical suffix in this pair carries the more concrete, everyday sense; -ic carries the abstract, technical sense.
Worked Example 6 — practical vs practicable
Stem: Your plan is interesting but not _____.
Options: (a) practical (b) practicable (c) practising (d) practiced
Sense: Two meanings collide here. Practical = useful in real life; practicable = capable of being done. The sentence says the plan is "interesting but" — implying a flaw of feasibility.
Answer: (b) practicable (= feasible).
Discrimination: A plan can be practical (useful if executed) yet not practicable (no way to execute it). Hard pair — keep both senses sharp.

Five Traps NDA Exploits
- The wrong-POS trap. A confusable pair split by part of speech, but the wrong member is the right POS. Advice (noun) where advise (verb) belongs, or vice versa.
- The wrong-shade trap. Both options are the right POS, but only one carries the right meaning shade. Economic crisis vs economical use.
- The visual-similarity trap. Two pairs whose words look so alike that the eye picks the wrong one even when the mind knows the answer. Stationary/stationery is the textbook case.
- The sound-alike trap. In a dictation-style sentence (rare in NDA but possible), the homophone partner sneaks in. Their/there/they're.
- The BrE/AmE trap. NDA uses BrE conventions. Practise (verb) / practice (noun) hold in BrE; AmE uses practice for both. Stick to BrE.
Every Sunday, write five confusable pairs from memory along with their distinction and one example sentence each. Five minutes. Over twelve weeks you will have covered 60 pairs with active recall, which beats reading 600 pairs passively.
Preparation Strategy
4-Week Confusables Plan
- Week 1: Bank A (20 most-tested pairs). Use the three-question method on five PYQ-style items per day.
- Week 2: Bank B (Latin/Greek roots). Add three new pairs to your personal confusables list per day, drawn from any reading.
- Week 3: Bank C (homophones) and Bank D (triples). Begin mixed daily quizzes.
- Week 4: Full revision. Self-test on all 80 pairs in 40 minutes. Anything missed goes to a final "danger pair" list for exam-week revision.
The Editorial Habit
Every confusable on this page appears in good newspaper writing almost weekly. Read one editorial per day (The Hindu, Indian Express). When you spot a confusable, write the sentence in a notebook. By exam day this notebook is worth more than any commercial confusables list — because every pair in it has earned its place through real usage.

Start Free Mock TestFrequently Asked Questions
Does NDA always have a Paired Words / Confusables block?
Not always as a dedicated block. The skill is tested most weeks across the paper — inside Spotting Errors, Sentence Improvement, and Fill in the Blanks. So while the standalone block may be missing in a given paper, the underlying skill scores you marks in many places.
What is the difference between paronyms, homonyms, and homophones?
Paronyms share a root and look alike but differ in meaning (economic/economical). Homonyms are spelled and pronounced the same but have unrelated meanings (bank = river / financial). Homophones sound alike but spell differently (their/there/they're).
How many confusable pairs should I learn?
Eighty high-frequency pairs (covered by the four banks on this page) handle the vast majority of NDA's range. Add ~20 more from any reading you do, and you will be over-prepared.
What is the fastest way to remember a difficult pair?
Build a personal memory trick. Stationary/stationery → "stationery has envelopes". Principal/principle → "the principal is your pal". The trick does not need to be elegant; it needs to be yours.
Should I follow British or American conventions?
British English. NDA follows BrE in spelling, vocabulary, and conventions. Practise (verb) / practice (noun). Colour, behaviour, organise, centre.
How is this topic related to vocabulary?
Confusables are vocabulary with extra trap-density. The discrimination skill you build for confusables transfers directly to Synonyms (where look-alike traps are common) and Antonyms (where synonym-traps are common).
Which NDA English topics test confusables most?
Spotting Errors uses wrong-confusable as a frequent error type. Fill in the Blanks tests pair-discrimination directly. Sentence Improvement sometimes replaces a confusable with its partner.
