Phonics breakdown
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: Letter B
Sound“b”·/b/
The letter B makes the /b/ sound, like in 'bat', 'big', and 'bug'. Both lips press together then release.
B is a voiced bilabial stop — both lips press together and release with voice. It always makes the /b/ sound except when silent at the end of words after m (as in 'lamb' or 'comb').
Tip
B looks like a bat — and bat starts with /b/!
Examples
Phonics Rule: STR Blend
Sound“str”·/str/
S, T, and R blend together — you hear all three! Like in 'strong' and 'street'.
STR is a three-letter consonant blend. You hear /s/, /t/, and /r/ spoken quickly together. It always appears at the beginning of a word.
Examples
When the letter E appears in a closed syllable, it usually makes the short E sound “eh”. This is often confused with short I by new readers.
Tip
E says “eh” like an egg on your head.
Examples
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: 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.
