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: 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: Double Consonant
Two of the same consonant together make just one sound, like the LL in 'ball' or TT in 'butter'.
When two identical consonants appear together, they make just one consonant sound, and the doubling signals a short vowel before it. A common case is the FLOSS rule: a one-syllable word with a short vowel doubles a final f, l, s, or z (off, ball, miss, buzz). Examples: ball, butter, happy, mitten, egg, off.
Tip
Double consonants make one sound — ball, butter, egg!
Examples
Phonics Rule: Open Syllable U — /uː/ (Long U)
In an open syllable, when U follows L, R, S, or J it says 'oo' instead of 'yoo' — like in 'su-per' and 'tru-ly'.
Same open-syllable pattern as the companion Open Syllable U (/juː/) rule, but when the lone U follows L, R, S, or J it drops the Y-glide and says pure /uː/ (su-per, ru-by, tru-ly). Same letter, different sound depending on what comes before it.
Tip
After L, R, S, J — U says oo, not yoo!
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!
