The trap-word bank: silent letters and inherited mistakes

These words are misspelt the same way by lakhs of candidates, which is exactly why examiners choose them. Each carries one hidden letter or one missing letter:

Groups inside the bank:

  • Silent letters preserved: government (n), environment (n), rhythm (no vowel but y), queue, vacuum (uu), liaison (i), silhouette (t,h).
  • Missing-letter classics: truly (no e), argument (argue drops e), ninth (nine drops e), forty (no u), publicly (no 'al'), definite (not -ate).
  • Foreign borrowings: restaurant (au), guarantee (gua), bureaucracy (eau), connoisseur, camaraderie, questionnaire, millennium.
  • -ceed vs -cede: only THREE words take -ceed: proceed, succeed, exceed. Everything else takes -cede: concede, recede, precede. And one loner: supersede is the only -sede in English.
  • Plurals: criteria (not criterias), phenomena (not phenomenas), stimuli, analyses, crises — plural already means many; adding s doubles it wrongly.

Revise this bank weekly; it is the single highest-yield page in the topic.

Detailed notes

Three words to look at closely

  • parallel has one r and a double l in the middle, with a single l at the end: p-a-r-a-l-l-e-l.
  • skiing is right (ski + ing); the only misspelling tested is 'sking'.
  • ninth: nine drops its e before -th (ninth), but keeps it in ninety and nineteen. Also, cacti and cactuses are both accepted plurals, and both collectable and collectible are standard. Neither of these should be the only answer in an item.

Silent letters

Many trap words have a letter you do not pronounce:

  • Silent p: psychology, pneumonia, receipt, cupboard, raspberry.
  • Silent d: Wednesday, handkerchief, grandson.
  • Silent b: debt, doubt, subtle, plumber, tomb.
  • Silent h: rhythm, rhyme, exhaust, exhibition, ghost.
  • Silent s: island, aisle, debris.
  • Silent n after m: autumn, column, condemn, solemn. Say the word slowly the way it is spelt (WED-NES-DAY) to remember the silent letter.

-ceed, -cede and -sede

  • -ceed: only proceed, succeed, exceed (and their forms: proceedings, succeeded, exceeding).
  • -sede: only supersede.
  • -cede: every other word — precede, recede, concede, secede, intercede. Also note the vowel change in the related words: proceed -> procedure and succeed -> success keep the c but not the double e.

When a root word changes its letters

  • pronounce -> pronunciation — the o after 'pron' disappears (pro-NUN-ci-a-tion).
  • explain -> explanation, maintain -> maintenance, exclaim -> exclamation — ai becomes a or e.
  • curious -> curiosity, generous -> generosity — the u disappears.
  • four -> forty (but fourteen), nine -> ninth.
  • argue -> argument, true -> truly, due -> duly. Remember these as pairs; the exam usually offers a spelling that keeps the root unchanged.

Borrowed words

French and Latin borrowings keep their original spelling:

  • entrepreneur (entre + pre + neur), bureaucracy (bureau + cracy), connoisseur, rendezvous, reservoir, silhouette, camaraderie, liaison, questionnaire. Break them into parts: bureau + cracy, entre + pre + neur. The common mistake is to swap letters within a part ('entreprenuer').

Quick revision

  • Silent letters: psychology, Wednesday, subtle, rhythm, island, autumn.
  • Only proceed, succeed and exceed end in -ceed; only supersede ends in -sede; everything else ends in -cede.
  • Root changes: pronunciation, explanation, forty, ninth, argument, truly.
  • Borrowed words: learn by parts (bureau + cracy, entre + pre + neur).
  • Parallel = one r, double l in the middle.

Types of questions asked

Every way this subtopic shows up in exams — how to recognise it, the formula or logic to use, and a solved example.

Type 1: Silent lettervery common2 practice Q
How to spot it:

The word contains a letter you do not pronounce (Wednesday, psychology, subtle) and one or more options leave it out.

  1. Recall the silent letter by saying the word as it is spelt (WED-NES-DAY).
  2. Remove every option that drops it.
  3. Check the order of the remaining letters.

Why it works: the most common mistake is to spell the word the way it sounds.

Example: Wednesday / Wendesday / Wensday / Wednsday

Wednesday — Wed + nes + day; the d is silent but written.

Type 2: -ceed, -cede or -sedecommon2 practice Q
How to spot it:

The options differ in -ceed / -cede / -sede, or in the vowel before it (precede, succeeded, exceed).

  1. Is it proceed, succeed or exceed? Then -ceed.
  2. Is it supersede? Then -sede.
  3. Otherwise -cede.

Why it works: the list of exceptions is only four words long.

Example: Precede / Preceed / Presede / Priceed

Precede — not one of the three -ceed words, so -cede.

Type 3: Root letter changed in the longer wordcommon2 practice Q
How to spot it:

The word comes from a root that changes its letters: pronounce -> pronunciation, nine -> ninth, four -> forty.

  1. Think of the root and how it changes.
  2. Remove the option that keeps the root unchanged (pronounciation, nineth).
  3. Check the remaining options letter by letter.

Why it works: the most common wrong option keeps the root word as it is.

Example: Pronunciation / Pronounciation / Pronuntiation / Prononciation

Pronunciation — the o of pronounce disappears: pro-nun-ci-a-tion.

Type 4: Borrowed wordcommon2 practice Q
How to spot it:

A French or Latin borrowing: entrepreneur, bureaucracy, connoisseur, rendezvous, silhouette.

  1. Split the word into parts: bureau + cracy.
  2. Check each part in each option.
  3. Remove options with swapped letters inside a part (entreprenuer).

Why it works: borrowed words keep their original spelling, so checking part by part is reliable.

Example: Bureaucracy / Beaurocracy / Bureaucrasy / Burocracy

Bureaucracy — bureau + cracy.

Shortcut tricks

⚡ The n-test for -ment words

government = govern+ment, environment = environ+ment: the root's final n must survive. Ask 'what is the root?' — the letter reappears.

⚡ Three -ceed, one -sede

proceed, succeed, exceed = the only -ceed words; supersede = the only -sede. All other 'seed-sound' words are -cede.

⚡ No- doubling plurals

criteria, phenomena, stimuli, data already are plurals — any option adding -s to them is instantly wrong.

Where students lose marks

  • Writing 'gaurantee' — swap of a and u; gua-rantee.

  • Writing 'greatful' — grate + ful; 'great' is not in the word.

  • Writing 'alot' — it is always two words: a lot.

  • Writing 'calender' for the date-chart — the machine spelling.
