Phonics breakdown
Phonics Rule: Letter 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
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: Short I
The letter I makes a short sound, like in 'sit' and 'big'.
When the letter I appears in a closed syllable, it usually makes the short I sound /ɪ/. This is one of the trickiest short vowels because it sounds similar to short E.
Tip
I says /ɪ/ like an itch you can't miss.
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.
