Phonics breakdown
Phonics Rule: Letter S
Sound“s”·/s/
The letter S usually makes the /s/ sound, like in 'sun', 'sit', and 'sock'. Air hisses through a small gap.
S is a voiceless alveolar fricative when it makes the /s/ sound. At the end of many words it can also make a /z/ sound (as in 'dogs' or 'has'). At the start of a word it is always /s/.
Tip
S hisses like a snake — sssssun!
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 R
Sound“r”·/r/
The letter R makes the /r/ sound, like in 'run', 'red', and 'rope'. The tongue curls back slightly.
R is a voiced approximant. The tongue curls back or bunches up without touching the roof of the mouth. When R follows a vowel it changes that vowel's sound (r-controlled vowels).
Tip
R is for run — /r/ with a curl of the tongue!
Examples
Phonics Rule: Open Syllable E (Long E)
Sound“ee”·/iː/
When E is the last letter of a syllable, the syllable is open and the E says its name “ee” — like in 'he' and 'me'.
This is the open-syllable pattern: a syllable that ends in a vowel leaves it 'open', so it says its long name. Here, a lone E at the end of a syllable says “ee” (he, me, we, be). The long E sound is also spelled other ways, each its own rule — vowel teams (ee in tree, ea in read) — but those are not open syllables.
Tip
Long E says its name — E!
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.
