Phonics breakdown
Phonics Rule: Prefix UN-
Sound“uhn”·/ʌn/
UN- means 'not' or 'the opposite of'. 'Unhappy' means 'not happy'.
The prefix un- is added to the beginning of a word to mean 'not' or to reverse an action. 'Happy' → 'unhappy' (not happy). 'Do' → 'undo' (reverse doing).
Tip
UN makes it undone — unhappy, unfair, unlike!
Examples
Phonics Rule: ST Blend
Sound“st”·/st/
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
When the letter O appears in a closed syllable, it usually makes the short O sound “ah”. In American English, this sounds like 'ah'.
Tip
O says “ah” like 'Ahh!' said the doctor.
Examples
Phonics Rule: Double Consonant
Sound“one sound”
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 -ABLE
Sound“uh-bul”·/əbəl/
The suffix -ABLE means 'can be done'. It turns verbs into adjectives.
-ABLE means capable of: readable = can be read, washable = can be washed, breakable = can be broken. The vowel in -ABLE uses the schwa sound “uh”, making it sound like 'uh-bul'.
Tip
-ABLE means you're able to do it — readable means you can read it!
