Phonics breakdown
Phonics Rule: ST Blend
S and T blend together — you hear both sounds! Like in 'stop' and 'fast'.
The blend ST combines /s/ and /t/ spoken quickly together. It can appear at the beginning or end of a word.
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: 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: Suffix -EST
Adding -EST means 'the most', like 'biggest' and 'fastest'.
The suffix -est makes a superlative — it means 'the most' of something. 'Big' → 'biggest' means the most big of all.
