Phonics breakdown
Phonics Rule: Hard C
Sound“k”·/k/
C makes the /k/ sound before A, O, U, or a consonant, like in 'cat' and 'cup'.
The letter C makes the hard /k/ sound when followed by A, O, U, or a consonant. This is the default C sound. Examples: cat, cup, coat, cold, crab, class.
Tip
C says K before A, O, U — cat, cup, coat!
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: 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
Phonics Rule: Plural -S (/s/ sound)
Sound“s”·/s/
After a quiet sound like p, t, k or f, the plural ending says /s/ — like 'cats' and 'cakes'.
Say 'ssss' and then 'zzzz' with a finger on your throat — only 'zzzz' buzzes. When the word already ends in a quiet (unvoiced) sound like p, t, k or f, the plural ending stays quiet too and says /s/. This happens whether the word is spelled -s (cats) or -es (cakes, notes), because in cakes the e is silent and only the s is sounded.
