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: 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: CK Digraph
CK together makes the /k/ sound, like in 'back' and 'kick'.
The digraph 'ck' appears right after a short vowel at the end of a one-syllable word. If the vowel is short, use CK. If the vowel is long, use just K (like 'make').
Tip
Short vowel? CK comes quick — back, kick, duck!
Examples
Phonics Rule: Suffix -NESS
Adding -NESS turns a describing word into a thing, like 'happy' → 'happiness'.
The suffix -ness turns an adjective into a noun. It means 'the state of being [adjective]'. 'Happy' → 'happiness' = the state of being happy.
