Phonics breakdown
Phonics Rule: Soft C
C says /s/ before E, I, or Y, like in 'city' and 'face'.
When C comes before the letters E, I, or Y, it makes the soft /s/ sound instead of the hard /k/ sound. This is called 'Soft C'.
Tip
C is soft before E, I, Y — the city is nice!
Examples
Phonics Rule: Open Syllable E (Long E)
When E is the last letter of a syllable, the syllable is open and the E says its name /iː/ — like in 'he' and 'me'.
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 E at the end of a syllable says /iː/ (he, me, we, be). The long E sound is also spelled other ways, each its own rule — vowel teams (ee in tree, ea in read) — but those are not open syllables.
Tip
Long E says its name — E!
Examples
Phonics Rule: Letter 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
Phonics Rule: Letter S
The letter S usually makes the /s/ sound, like in 'sun', 'sit', and 'sock'. Air hisses through a small gap.
S is a voiceless alveolar fricative when it makes the /s/ sound. At the end of many words it can also make a /z/ sound (as in 'dogs' or 'has'). At the start of a word it is always /s/.
Tip
S hisses like a snake — sssssun!
Examples
Phonics Rule: Open Syllable E (Long E)
When E is the last letter of a syllable, the syllable is open and the E says its name /iː/ — like in 'he' and 'me'.
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 E at the end of a syllable says /iː/ (he, me, we, be). The long E sound is also spelled other ways, each its own rule — vowel teams (ee in tree, ea in read) — but those are not open syllables.
Tip
Long E says its name — E!
Examples
Phonics Rule: Schwa
In unstressed syllables, vowels often make a lazy 'uh' sound called schwa, like the A in 'about'.
Schwa /ə/ is the most common vowel sound in English. Any vowel letter can make the schwa sound when it's in an unstressed syllable. It sounds like a quick, lazy 'uh'.
Tip
Schwa is lazy — any vowel can say 'uh' when it's not stressed!
Examples
Phonics Rule: Plural -S (/z/ sound)
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.
