Phonics breakdown
Phonics Rule: Letter P
Sound“p”·/p/
The letter P makes the /p/ sound, like in 'pan', 'pig', and 'pot'. Both lips press together then pop open.
P is a voiceless bilabial stop — both lips press together and release with a puff of air but no voice. It pairs with B (which is the voiced version of the same mouth position).
Tip
P pops open — press your lips and let it POP!
Examples
Phonics Rule: R-Controlled ER
Sound“er”·/ɜːr/
When R comes after E, it makes the “er” sound, like in 'her' and 'fern'.
ER makes the same sound as IR and UR — they all say “er”. ER is the most common spelling of this sound, especially at the end of words.
Tip
ER, IR, and UR all sound the same — Bossy R wins again!
Examples
Phonics Rule: SP Blend
Sound“sp”·/sp/
S and P blend together — you hear both sounds! Like in 'spin' and 'sport'.
The blend SP combines /s/ and /p/ spoken quickly together.
Examples
Phonics Rule: Schwa
Sound“uh”·/ə/
In unstressed syllables, vowels often make a lazy 'uh' sound called schwa, like the A in 'about'.
Schwa “uh” is the most common vowel sound in English. Any vowel letter can make the schwa sound when it's in an unstressed syllable. It sounds like a quick, lazy 'uh'.
Tip
Schwa is lazy — any vowel can say 'uh' when it's not stressed!
Examples
Phonics Rule: Hard C
Sound“k”·/k/
C makes the /k/ sound before A, O, U, or a consonant, like in 'cat' and 'cup'.
The letter C makes the hard /k/ sound when followed by A, O, U, or a consonant. This is the default C sound. Examples: cat, cup, coat, cold, crab, class.
Tip
C says K before A, O, U — cat, cup, coat!
Examples
Phonics Rule: Open Syllable A (Long A)
Sound“ay”·/eɪ/
When A is the last letter of a syllable, the syllable is open and the A says its name “ay” — like in 'ba-by' and 'pa-per'.
This is the open-syllable pattern: a syllable that ends in a vowel leaves that vowel 'open', so it says its long name. Here, a lone A at the end of a syllable says “ay” (ba-by, a-pron, lady). The long A sound is also spelled other ways, each its own rule — silent E (cake), or vowel teams (ai in rain, ay in play) — but those are not open syllables.
Tip
Long A says its name — A!
Examples
Phonics Rule: CI says “sh”
Sound“sh”·/ʃ/
Before another vowel, CI often says “sh”, like in 'special' and 'musician'.
When CI comes before another vowel (usually A, O, or E), the two letters blend into the “sh” sound: special, crucial, musician, glacier, delicious. This is common in words ending -cial and -cian.
Tip
CI before a vowel whispers “sh” — a special musician!
Examples
Phonics Rule: OU says “uh” (-ous)
Sound“uh”·/ə/
OU says the lazy schwa “uh” in the ending -OUS, like in 'famous' and 'generous'.
In the suffix -ous, OU is unstressed and says schwa “uh”: famous, generous, nervous, dangerous, enormous.
Tip
- OUS is famous for the lazy uh — famous, nervous!
Examples
Phonics Rule: Plural -S (/z/ sound)
Sound“z”·/z/
After a buzzing sound or a vowel, the plural ending says /z/ — like 'dogs' and 'shoes'.
Put a finger on your throat and say 'zzzz' — you feel a buzz. When the word ends in a buzzing (voiced) sound or a vowel, the plural ending buzzes too and says /z/. This happens whether the word is spelled -s (dogs) or -es (shoes, trees), because in shoes the e is silent and only the s is sounded. Most people never notice they are doing this.
