Phonics breakdown
Phonics Rule: Letter 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
When R comes after E, it makes the /ɜːr/ sound, like in 'her' and 'fern'.
ER makes the same sound as IR and UR — they all say /ɜːr/. 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
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
In unstressed syllables, vowels often make a lazy 'uh' sound called schwa, like the A in 'about'.
Schwa /ə/ 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
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)
When A is the last letter of a syllable, the syllable is open and the A says its name /eɪ/ — 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 /eɪ/ (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/
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 /ə/ (-ous)
OU says the lazy schwa /ə/ in the ending -OUS, like in 'famous' and 'generous'.
In the suffix -ous, OU is unstressed and says schwa /ə/: famous, generous, nervous, dangerous, enormous.
Tip
- OUS is famous for the lazy uh — famous, nervous!
Examples
Phonics Rule: Plural -S (/z/ sound)
After voiced sounds, -S says /z/, like in 'dogs' and 'birds'.
After voiced consonants and vowels, the plural -s says /z/. Most people don't notice this — it sounds natural.
