Phonics breakdown
Phonics Rule: Open Syllable U — /juː/ (Long U)
When U is the last letter of a syllable, the syllable is open and the U says its name with a /j/ glide — like in 'mu-sic' and 'hu-man'.
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 U at the end of a syllable says /juː/ (mu-sic, hu-man, u-nit). After L, R, S, or J the Y-glide drops and U says /uː/ instead — see the companion Open Syllable U (/uː/) rule.
Tip
Long U says its name with a YOO sound!
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: Short E
The letter E makes a short sound, like in 'bed' and 'red'.
When the letter E appears in a closed syllable, it usually makes the short E sound /ɛ/. This is often confused with short I by new readers.
Tip
E says /ɛ/ like an egg on your head.
Examples
Phonics Rule: Letter F
The letter F makes the /f/ sound, like in 'fish', 'fun', and 'fox'. The upper teeth touch the lower lip.
F is a voiceless labiodental fricative — the upper front teeth rest on the lower lip while air flows through to make the /f/ sound. It is very consistent.
Tip
F is for fish — and fish starts with /f/!
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: 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: Suffix -NESS
Adding -NESS turns a describing word into a thing, like 'happy' → 'happiness'.
The suffix -ness turns an adjective into a noun. It means 'the state of being [adjective]'. 'Happy' → 'happiness' = the state of being happy.
