Phonics breakdown
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: Letter X
The letter X usually makes the /ks/ sound, like in 'fox', 'box', and 'mix'.
X is unusual — it represents two sounds blended together: /k/ + /s/ = /ks/. At the start of a word it sometimes makes a /z/ sound (xylophone). At the end of words it reliably says /ks/.
Tip
X says /ks/ — like a fox in a box!
Examples
Phonics Rule: Soft G
G sometimes says /dʒ/ (like J) before E, I, or Y, like in 'gem' and 'giant'.
When G comes before E, I, or Y, it sometimes makes the soft /dʒ/ sound (like J). However, this rule has many exceptions ('get', 'give', 'girl').
Tip
G can be gentle like a giant!
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 N
The letter N makes the /n/ sound, like in 'net', 'nap', and 'nut'. The tongue tip touches behind the upper teeth.
N is a voiced alveolar nasal — the tongue tip touches the ridge behind the upper teeth while voice hums through the nose. It is one of the most common consonants in English.
Tip
N hums through the nose — say /n/ and feel the buzz!
