Phonics breakdown
Phonics Rule: Letter Z
The letter Z makes the /z/ sound, like in 'zip', 'zoo', and 'buzz'. It buzzes like a bee.
Z is a voiced alveolar fricative — air hisses through a small gap with voice added, creating a buzzing sound. It is the voiced partner of S. Double Z (zz) makes the same /z/ sound.
Tip
Z buzzes like a bee — zzzzzip!
Examples
Phonics Rule: R-Controlled ER
When R comes after E, it makes the /ɜːr/ sound, like in 'her' and 'fern'.
ER makes the same sound as IR and UR — they all say /ɜːr/. ER is the most common spelling of this sound, especially at the end of words.
Tip
ER, IR, and UR all sound the same — Bossy R wins again!
Examples
Phonics Rule: Open Syllable O (Long O)
When O is the last letter of a syllable, the syllable is open and the O says its name /oʊ/ — 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 /oʊ/ (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!
