Spelling rules and patterns

English spelling follows patterns. Learning the main rules helps you spell tricky words and spot mistakes in 11+ papers.

Adding suffixes (endings)

Words ending in a silent 'e'

Drop the e before a vowel suffix (-ing, -ed, -er):

  • hope → hoping, make → making, ride → rider.

Keep the e before a consonant suffix (-ly, -ment):

  • hope → hopeful, move → movement.

The "1-1-1" doubling rule

For a short word ending in one vowel + one consonant, double the final consonant before a vowel suffix:

  • run → running, stop → stopped, big → bigger.

Words ending in 'y'

Change y to i when adding a suffix (unless it follows a vowel):

  • happy → happiness, carry → carried. But: play → played (vowel before y).

"i before e" rule

i before e, except after c (when the sound is "ee"):

  • believe, field, but receive, ceiling.

(Watch out for exceptions like weird and seize.)

Making plurals

  • Most words: add -s (cat → cats).
  • Words ending in s, x, ch, sh: add -es (box → boxes, church → churches).
  • Words ending in consonant + y: change to -ies (baby → babies).
  • Some words ending in f: change to -ves (leaf → leaves, knife → knives).

Prefixes

A prefix goes at the front and changes meaning (un-, dis-, re-, pre-). The spelling of the root doesn't change: un + happy = unhappy; dis + appear = disappear (two s's? no — dis + appear).

Worked example

Add "-ing" to swim and hope.

  • swim → short word, one vowel + one consonant → double the m → swimming.
  • hope → ends in silent e → drop the e → hoping. ✓

Common mistakes

  • Forgetting to double the consonant (runing instead of running).
  • Not changing y to i (carryed instead of carried).
  • Adding an extra letter with prefixes (unnhappy).

Top tips

  • Say the word slowly and break it into sounds (syllables).
  • Learn the small list of common exceptions.
  • When unsure about a suffix, check: silent e? short word? ends in y?

Quick recap

  • Drop silent e before a vowel suffix; double the final consonant in short 1-1-1 words; change y to i.
  • "i before e except after c" (ee sound); plurals add -s/-es/-ies/-ves.
  • Prefixes don't change the root's spelling.
