Spelling patterns
Why is "saw" spelled with AW and "sauce" with AU — and does it even make a difference?
English often uses different letter combinations to represent the same sound. These combinations are called digraphs. Learning where they typically appear in a word helps you choose the correct spelling.
AW and AU (same sound, different positions)
Both aw and au usually make the same sound (as in caught).
AW often appears at the end of a word or before a final consonant:
saw, law, draw, yawn, crawl, hawk
AU usually appears in the middle or beginning:
author, August, cause, pause, sauce
This is a strong tendency, not a perfect rule.
AL and the “aw” sound
Before the letter L, the vowel A often changes sound:
call, fall, walk, talk, always, almost
In many of these words, A sounds closer to “aw” or “o”.
OI and OY
Both make the “oy” sound:
OI → usually in the middle:
coin, join, voice, point
OY → usually at the end:
boy, toy, enjoy
This is a reliable pattern.
W and WH
W starts many common words:
win, water, word
WH appears in question words:
what, when, where, which, who
In modern English, W and WH usually sound the same.
TR and THR
These are consonant blends:
TR: tree, train, trip
THR: three, throw, through
The difference is the added “th” sound.
The letter X
X usually makes a “ks” sound:
box, mix, extra
At the start of some words, it can sound like “z”:
xylophone
Endings: -dge, -tch, -ge, -ch
After a short vowel:
-dge: badge, edge
-tch: catch, fetch
After a long vowel or consonant:
-ge: page, huge
-ch: beach, teach
The extra letter (d or t) protects the short vowel.
Endings for long E sound
Several spellings can make a long E sound at the end:
-y: happy, city
-ee: tree, coffee
-ey: money, key
-ie: cookie, movie
These must often be learned by word group.
How to choose the correct spelling
When spelling a sound:
• Think about its position (start, middle, end)
• Recall common patterns (oi in middle, oy at end)
• Use familiar word examples as models
English spelling is based on patterns, not random choices.
Key idea
Different spellings can represent the same sound, but they often follow position-based patterns.
Recognising these patterns helps you make better spelling choices.
