Spelling Rules
Spelling rules are consistent patterns in English that help us spell and read words more accurately and confidently.
What You Need to Know
Key Concept Diagram
The "i before e except after c" rule helps with words like believe (ie) and receive (ei after c)
When adding -ing or -ed to words ending in a single vowel + consonant, double the final consonant (e.g. run → running)
Words ending in a silent e usually drop the e before adding a vowel suffix (e.g. hope → hoping)
Homophones are words that sound the same but are spelled differently and have different meanings (e.g. their/there/they're)
More Spelling Patterns
Once you know a pattern, you can spell dozens of words correctly — not just one. Here are three more patterns that come up all the time.
Plurals ending in -es
Most words just add -s to become plural (cat → cats). But words ending in x, s, sh, or ch add -es instead, because you need an extra syllable to say the plural out loud.
fox → foxes, bus → buses, brush → brushes, watch → watches
Prefixes don't change the root word
A prefix is added to the front of a word. Unlike suffixes, prefixes never change the spelling of the word they're attached to — you just join them straight on.
happy → unhappy, do → redo, agree → disagree
Short vowel vs long vowel before -ing
This is why some words double their last letter before -ing and others don't: it depends on whether the vowel sound is short or long.
hop (short o) → hopping | hope (long o, silent e) → hoping
How to Check Your Spelling
When you're not sure how to spell a word, work through it step by step instead of guessing.
A Step-by-Step Checking Method
- Say the word slowly, breaking it into syllables.
- Ask: does a spelling rule apply here (plural, prefix, suffix, silent e)?
- Write the word, then look at it — does it "look right" to you?
- Check it against a word you already know that follows the same pattern.
- If you're still unsure, look it up and add it to a personal tricky-words list.
Worked Examples
Spelling the plural of "fox"
Step 1: "Fox" ends in x.
Step 2: Words ending in x, s, sh or ch add -es, not just -s.
Answer: foxes
Adding the prefix "un-" to "happy"
Step 1: "Un-" is a prefix, added to the front of the word.
Step 2: Prefixes never change the spelling of the root word — just join them on directly.
Answer: unhappy (not "inhappy" or "dishappy")
"hop" vs "hope" before -ing
Step 1: "Hop" has a short vowel sound, so double the final consonant: hopping.
Step 2: "Hope" ends in a silent e, so drop the e before adding -ing: hoping.
Answer: Same three letters at the start, two different rules — always check the vowel sound first.
