The trap-word bank: silent letters and inherited mistakes

🔒 Log in to track
⏱ 4 min read🧩 6 question types🎯 16 practice Q
The idea in one minute

Some words are spelt wrongly again and again, so setters choose them. Each one hides a silent letter, a missing letter or a borrowed pattern. Learn the bank in small groups, and give each word a hook.

01

The word bank

Each word has one hidden letter or one missing letter. Use the hook.

CorrectHook
privilegeno d anywhere: priv-i-lege
rhythmno vowel except y: Rh-y-th-m
governmentthe n of govern stays: govern + ment
environmentthe n of environ stays: environ + ment
separatethere is 'a rat' in sePArATE
desperatedespERate: it ends in -erate
definiteends in -inite: finite is inside
restaurantrest-au-rant: the au sits in the middle
guaranteegua first, then rantee
calendarends in -dar (a calender is a machine)
queuefive letters, only q speaks
vacuumdouble u: vac-uum
liaisonlia-ison
gratefulgrate + ful

Tip: Say the hook aloud once. Then cover the word and write it.

02

Silent letters

Many trap words have a letter you do not say.

  • 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 as it is spelt (WED-NES-DAY) to remember the silent letter.

03

-ceed, -cede and -sede

  • -ceed: only proceed, succeed and exceed
  • -sede: only supersede
  • -cede: every other word: precede, recede, concede, secede, intercede

Rule: Three words end in -ceed, one ends in -sede, and all the rest end in -cede.

The related words procedure and success do not follow the same pattern. Procedure has one e, and success has a double c.

04

When a root word changes

The longer word often changes the root. The wrong option keeps the root unchanged.

  • pronounce, pronunciation (the o goes)
  • explain, explanation
  • maintain, maintenance
  • exclaim, exclamation
  • curious, curiosity
  • four, forty (but fourteen)
  • nine, ninth (but ninety and nineteen)
  • argue, argument; true, truly; due, duly
05

Borrowed words

French and Latin words keep their original spelling. Break them into parts.

  • entrepreneur: entre + pre + neur
  • bureaucracy: bureau + cracy
  • connoisseur, rendezvous, reservoir, silhouette, camaraderie, liaison, questionnaire

The usual mistake is to swap letters inside a part, as in entreprenuer.

06

Words to look at closely

  • parallel has one r, a double l in the middle, and a single l at the end.
  • skiing is right (ski + ing). Only sking is a wrong option.
  • cacti and cactuses are both accepted plurals.
  • collectable and collectible are both standard.
07

Question types you will see

Each type: how to recognise it, the method step by step, and one question to try.

Type 1very common2 practice Q

Silent letter

How to spot it:

The word contains a letter you do not say (Wednesday, psychology, subtle) and some options leave it out.

Method
  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 other letters.

Why it works:

The most common mistake is to spell the word as it sounds.

Try this

Wednesday / Wendesday / Wensday / Wednsday

Show solution
  1. Say it as spelt: Wed-nes-day.

  2. The d is silent but written.

  3. Only one option keeps it with all other letters.

Answer

Wednesday

Type 2common2 practice Q

-ceed, -cede or -sede

How to spot it:

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

Method
  1. Is it proceed, succeed or exceed? Then -ceed.

  2. Is it supersede? Then -sede.

  3. Otherwise choose -cede.

Why it works:

The list of exceptions is only four words long.

Try this

Precede / Preceed / Presede / Priceed

Show solution
  1. Precede is not proceed, succeed or exceed.

  2. It is not supersede.

  3. So it ends in -cede.

Answer

Precede

Type 3common2 practice Q

Root letter changed in the longer word

How to spot it:

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

Method
  1. Think of the root and how it changes.

  2. Remove the option that keeps the root unchanged.

  3. Check the remaining options letter by letter.

Why it works:

The most common wrong option keeps the root as it is.

Try this

Pronunciation / Pronounciation / Pronuntiation / Prononciation

Show solution
  1. Pronounce loses its o in the longer word.

  2. So it is pro-nun-ci-a-tion.

  3. Pronounciation keeps the root.

Answer

Pronunciation

Type 4common2 practice Q

Borrowed word

How to spot it:

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

Method
  1. Split the word into parts: bureau + cracy.

  2. Check each part in each option.

  3. Remove options with swapped letters inside a part.

Why it works:

Borrowed words keep their original spelling, so part-by-part checking is reliable.

Try this

Bureaucracy / Beaurocracy / Bureaucrasy / Burocracy

Show solution
  1. Split it: bureau + cracy.

  2. Beaurocracy swaps letters in bureau.

  3. Only one option has both parts right.

Answer

Bureaucracy

Type 5common

Missing letter: the root drops a letter

How to spot it:

The word is truly, argument, ninth, forty, publicly or duly, and a wrong option keeps the extra letter.

Method
  1. Think of the base: true, argue, nine, four, public.

  2. Note which letter drops: true and argue lose e, nine loses e, four loses u.

  3. Choose the option with the drop.

Why it works:

These words are tested by adding back the letter that the root loses.

Try this

Truly / Truely / Trully / Truley

Show solution
  1. The base is true.

  2. It drops its e before -ly.

  3. So the word is tru-ly.

Answer

Truly

Type 6common

Root letter survives: govern-ment

How to spot it:

The word ends in -ment (government, environment, embarrassment) and a wrong option drops a root letter.

Method
  1. Name the root: govern, environ, embarrass.

  2. Add -ment to the whole root.

  3. Check that no root letter is missing.

Why it works:

The suffix -ment joins the whole root, so its last letter stays.

Try this

Government / Goverment / Governmant / Govrnment

Show solution
  1. The root is govern.

  2. Add -ment: govern + ment.

  3. So the n stays.

Answer

Government

08

Shortcuts that save time

⚡ The n-test for -ment words

Government is govern + ment. Environment is environ + ment. The root's final n must survive. Ask what the root is, and the letter reappears.

Example

Which is correct: goverment or government?

Show solution
  1. The root is govern.

  2. Its n must stay before -ment.

Answer

government

⚡ Three -ceed, one -sede

Proceed, succeed and exceed are the only -ceed words. Supersede is the only -sede word. Every other word with this sound ends in -cede.

⚡ Plurals already plural

Criteria, phenomena and stimuli are already plurals. An option that adds -s to them (criterias) is wrong.

09

Mistakes to avoid

Where most students lose marks on this subtopic.

Mistake 01

Writing priviledge or goverment by sound.

Use the hook: privilege has no d. Government keeps the n of govern.

Mistake 02

Writing seperate or definate.

Separate has 'a rat' in it. Definite ends in -inite.

Mistake 03

Writing preceed or procede.

Only proceed, succeed and exceed end in -ceed. Precede ends in -cede.

Mistake 04

Keeping the root unchanged: pronounciation, nineth.

The root changes: pronunciation, ninth.

Mistake 05

Dropping the silent letter: Wensday, dout.

Say the word as it is spelt: Wednesday, doubt.

Mistake 06

Swapping letters in a borrowed word: entreprenuer.

Split it into parts: entre + pre + neur.

10

Quick revision

Read this the night before the exam.

  • Silent letters: psychology, Wednesday, subtle, rhythm, island, autumn.

  • Only proceed, succeed and exceed end in -ceed. Only supersede ends in -sede. All others end in -cede.

  • Root changes: pronunciation, explanation, forty, ninth, argument, truly.

  • Government and environment keep the n of the root.

  • Borrowed words: learn by parts (bureau + cracy, entre + pre + neur).

  • Parallel has one r and a double l in the middle.

  • Do not add -s to criteria, phenomena or stimuli.
