Phonics breakdown
Phonics Rule: Short O
The letter O makes a short sound, like in 'hot' and 'dog'.
When the letter O appears in a closed syllable, it usually makes the short O sound /ɑ/. In American English, this sounds like 'ah'.
Tip
O says /ɑ/ like 'Ahh!' said the doctor.
Examples
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: 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: Suffix -TION
-TION says /shun/! It turns verbs into nouns, like 'action' and 'nation'.
The suffix -tion is pronounced /ʃən/ (shun). It usually turns a verb into a noun: 'act' → 'action'. The TI makes a /ʃ/ sound, which is unusual for T.
Tip
TION says SHUN — the nation takes action!
