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
Phonics Rule: R-Controlled OR
Sound“or”·/ɔːr/
When R comes after O, it makes the “or” sound, like in 'for' and 'corn'.
OR makes the “or” sound. Unlike ER, IR, UR which all sound the same, OR has its own distinct sound. The companion rule r_controlled_or_er covers the “er” pronunciation after W (word, work).
Tip
OR — the horse in the corner says “or”!
Examples
When the letter I appears in a closed syllable, it usually makes the short I sound “ih”. This is one of the trickiest short vowels because it sounds similar to short E.
Tip
I says “ih” like an itch you can't miss.
Examples
Phonics Rule: Open Syllable O (Long O)
Sound“oh”·/oʊ/
When O is the last letter of a syllable, the syllable is open and the O says its name “oh” — like in 'go' and 'no'.
This is the open-syllable pattern: a syllable that ends in a vowel leaves it 'open', so it says its long name. Here, a lone O at the end of a syllable says “oh” (go, no, so, o-pen). The O also says its long name in the 'old' and 'ost' families (cold, most). The long O sound is also spelled other ways, each its own rule — silent E (home) or vowel teams (oa in boat, ow in snow) — but those are not open syllables.
Tip
Long O says its name — O!
Examples
Phonics Rule: Letter L
Sound“l”·/l/
The letter L makes the /l/ sound, like in 'lamp', 'leg', and 'lip'. The tongue tip touches behind the upper teeth.
L is a voiced lateral approximant — the tongue tip touches the ridge behind the upper teeth while air flows around the sides. Double L (ll) makes the same /l/ sound.
Tip
L is for lamp — light it up with /l/!
Examples
When the letter I appears in a closed syllable, it usually makes the short I sound “ih”. This is one of the trickiest short vowels because it sounds similar to short E.
Tip
I says “ih” like an itch you can't miss.
Examples
Phonics Rule: Plural -S (/z/ sound)
Sound“z”·/z/
After a buzzing sound or a vowel, the plural ending says /z/ — like 'dogs' and 'shoes'.
Put a finger on your throat and say 'zzzz' — you feel a buzz. When the word ends in a buzzing (voiced) sound or a vowel, the plural ending buzzes too and says /z/. This happens whether the word is spelled -s (dogs) or -es (shoes, trees), because in shoes the e is silent and only the s is sounded. Most people never notice they are doing this.
