Are there many exceptions to the 'i before e' rule?

There are some notable exceptions, including weird, seize, protein, caffeine, neither, and species. However, the rule holds true for the vast majority of common words where the 'ee' sound is made with ie or ei. Learning the exceptions separately is the best approach — there are only about a dozen common ones.

How do I know when to double a consonant before adding -ing or -ed?

Double the final consonant when the word has a single vowel followed by a single consonant and the stress is on the final syllable. For example: run → running, stop → stopped, begin → beginning. Do not double if there are two vowels (rain → raining), two consonants (jump → jumping), or the stress is on an earlier syllable (visit → visiting).

Why does 'beautiful' only have one L but 'beautifully' has two?

The suffix -ful always has one L (beautiful, wonderful, careful). When you then add the suffix -ly, you combine the single L from -ful with the L from -ly, creating a double L: beautifully, wonderfully, carefully. Both spellings are logical once you understand that they involve different suffixes.

How can I tell whether a word ends in -tion or -sion?

A helpful sound test: if you hear a crisp 'shun' sound, it is usually -tion (education, attention). If you hear a softer 'zhun' sound, it is -sion (television, decision). You can also look at the root word: if it ends in -t or -te, use -tion (create → creation); if it ends in -d, -de, or -se, use -sion (decide → decision, confuse → confusion).

I Before E & Other Spelling Rules for 11+

Why Spelling Rules Matter

English spelling can feel random and unpredictable, but it is not as chaotic as it seems. Most words follow patterns and rules, and learning these rules gives you a reliable system for spelling thousands of words correctly — including ones you have never seen before.

In the 11+ exam, spelling contributes to your SPaG mark (spelling, punctuation, and grammar). Every misspelt word costs marks, and frequent errors can also affect how examiners perceive your vocabulary choices. Learning the eight rules below will cover the vast majority of spelling challenges you will face.

Wooden letter blocks spelling out words to practise spelling rules

Rule 1: I Before E, Except After C

This is perhaps the most famous spelling rule in the English language. The full version is:

"I before E, except after C, when the sound is 'ee'."

I before E: believe, achieve, niece, field, piece, brief
Except after C: receive, deceive, ceiling, conceit, perceive

Best memory trick for i-before-e: Remember the full rule -- "I before E, except after C, when the sound is 'ee'." The last part is crucial and often forgotten. If the sound is not "ee" (as in "weight" or "vein"), the rule does not apply.

Exceptions: Several common words break this rule: weird, seize, protein, caffeine, neither, species. These simply need to be memorised. A helpful memory trick: "Weird is weird because it breaks the rule."

Common exceptions to memorise: weird, seize, protein, caffeine, neither, species. These words break the i-before-e rule and simply need to be learned individually. There are only about a dozen -- add them to your personal spelling list.

Rule 2: Doubling Consonants Before a Suffix

When adding a suffix that begins with a vowel (-ing, -ed, -er, -est) to a word that ends in a single consonant after a single vowel, double the final consonant.

run → running
stop → stopped
big → bigger, biggest
swim → swimmer, swimming
begin → beginning

When NOT to double: If the word ends in two consonants (jump → jumping), has two vowels before the consonant (rain → raining), or the stress is not on the final syllable (visit → visiting, not visitting), do not double.

Memory aid: Think of it as the consonant needing to "protect" the short vowel sound. If you do not double, the vowel sound changes: hoping (long 'o') vs hopping (short 'o').

Rule 3: Dropping the Silent E

When adding a suffix that begins with a vowel (-ing, -ed, -ous, -able) to a word ending in silent E, drop the E.

make → making
hope → hoping
fame → famous
love → lovable
dance → dancing

When to KEEP the E: Keep the E when the suffix begins with a consonant (-ment, -ful, -ly, -ness): hopeful, movement, lonely, awareness.

Exceptions: Keep the E before -able and -ous when the word ends in -ce or -ge (to preserve the soft sound): noticeable, changeable, courageous, traceable. Also: truly (not truely), argument (not arguement), ninth (not nineth).

Rule 4: Changing Y to I

When adding a suffix to a word ending in a consonant + Y, change the Y to I.

happy → happier, happiest, happiness, happily
beauty → beautiful
carry → carried, carrier
plenty → plentiful
easy → easier, easily

Exception: Do not change Y to I when adding -ing (carry → carrying, not carriing). English avoids having two I's next to each other.

When the Y follows a vowel: Keep the Y: play → played, enjoy → enjoyment, delay → delayed.

Rule 5: The -ful Suffix

The suffix -ful always has only one L, even though the word "full" has two.

beautiful (not beautifull)
wonderful (not wonderfull)
careful (not carefull)
hopeful (not hopefull)
grateful (not gratefull)

Memory aid: When "full" joins another word, it loses an L — think of it as making room for the word it is joining.

Note: When you then add -ly to these words, you get a double L: beautifully, wonderfully, carefully. This is correct because you are adding -ly to -ful.

Rule 6: The -ly Suffix

Adding -ly to turn an adjective into an adverb is usually straightforward, but there are a few patterns to learn:

Most words: Simply add -ly: quick → quickly, slow → slowly, quiet → quietly
Words ending in -le: Drop the -le and add -ly: gentle → gently, simple → simply, possible → possibly
Words ending in -y: Change Y to I and add -ly: happy → happily, easy → easily, angry → angrily
Words ending in -ic: Add -ally: basic → basically, dramatic → dramatically, tragic → tragically (exception: publicly)
Words ending in -ful: Add -ly to get -fully: hopeful → hopefully, careful → carefully

Rule 7: -tion and -sion Endings

These endings both make the "shun" sound, but which one to use depends on the root word.

Use -tion (the more common spelling):

After most consonants: invention, attention, education, description
When the root word ends in -t or -te: create → creation, complete → completion

Use -sion:

When the root word ends in -d or -de: decide → decision, explode → explosion, collide → collision
When the root word ends in -ss or -mit: discuss → discussion, permit → permission
When the root word ends in -se: confuse → confusion, tense → tension

Memory aid: If you can hear a "zhun" sound (as in television, vision, decision), it is almost always -sion. If you hear a crisp "shun" sound, it is usually -tion.

Rule 8: Tricky Plurals

Most plurals are formed by adding -s, but several patterns require special attention:

Words ending in -s, -sh, -ch, -x, -z: Add -es: bus → buses, wish → wishes, church → churches, box → boxes
Words ending in consonant + y: Change Y to I and add -es: story → stories, city → cities, family → families
Words ending in vowel + y: Just add -s: key → keys, day → days, monkey → monkeys
Words ending in -f or -fe: Change to -ves: knife → knives, leaf → leaves, wolf → wolves, life → lives (exceptions: roof → roofs, chief → chiefs)
Words ending in -o: Some add -es (potato → potatoes, tomato → tomatoes, hero → heroes), some add -s (piano → pianos, photo → photos). Words from other languages usually just add -s.

Irregular plurals to memorise: child → children, mouse → mice, tooth → teeth, foot → feet, person → people, man → men, woman → women, goose → geese, ox → oxen.

Putting the Rules into Practice

Knowing the rules is only half the battle — you need to practise applying them until they become automatic. Here is a study plan:

Week 1-2: Focus on Rules 1-4. Write ten words for each rule and test yourself daily.
Week 3-4: Focus on Rules 5-8. Pay particular attention to -tion/-sion and tricky plurals.
Ongoing: When you misspell a word in practice writing, identify which rule applies and add it to your revision list. Over time, your personal "tricky words" list will shrink as the rules become second nature.
