Spelling patterns

Spelling rules for plurals and adding suffixes, tricky letter patterns and homophones.

📌 Key points

  1. Most nouns add -s for plurals. Add -es after s, x, z, ch and sh: boxes, churches, wishes.
  2. Consonant + y: change y to i and add -es (baby → babies). Vowel + y: just add -s (day → days).
  3. Many words ending in -f or -fe change to -ves: leaf → leaves, knife → knives (but roof → roofs).
  4. Short vowel + one consonant: double the consonant before -ing or -ed: hop → hopping, stop → stopped.
  5. Words ending in silent e usually drop the e before -ing: make → making, hope → hoping.
  6. “i before e except after c” when the sound is “ee”: believe, field, receive, ceiling (a few exceptions, such as seize).
  7. Homophones sound the same but have different spellings and meanings: there/their/they're, to/too/two, where/wear.
  8. Common endings: -tion (station), -sion (television), -cian for jobs (musician), -ous (famous).
  9. Use Look, Say, Cover, Write, Check to learn tricky words.

✏️ Worked example

Add -ing to these verbs: swim, smile, play.

  1. swim: short vowel 'i' + one consonant 'm', so double it: swimming.
  2. smile: ends in silent e, so drop the e: smiling.
  3. play: ends in vowel + y, so just add -ing: playing.
  4. Answer: swimming, smiling, playing.
