Phonics breakdown
Phonics Rule: Silent K in KN
In KN, the K is silent! You only say /n/, like in 'know' and 'knee'.
When K comes before N at the beginning of a word, the K is completely silent. You only pronounce the N. This comes from Old English when the K was actually pronounced.
Tip
K is silent when N is next — knock, knock, who's there? Just N!
Examples
Phonics Rule: Short O
The letter O makes a short sound, like in 'hot' and 'dog'.
When the letter O appears in a closed syllable, it usually makes the short O sound /ɑ/. In American English, this sounds like 'ah'.
Tip
O says /ɑ/ like 'Ahh!' said the doctor.
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 -ING
Adding -ING to a verb shows something is happening right now, like 'running' and 'playing'.
The suffix -ing is added to verbs to show an ongoing action (present participle). Sometimes the base word changes: drop silent E ('make' → 'making'), double final consonant ('run' → 'running').
