Phonics breakdown
Phonics Rule: Prefix UN-
Sound“uhn”·/ʌn/
UN- means 'not' or 'the opposite of'. 'Unhappy' means 'not happy'.
The prefix un- is added to the beginning of a word to mean 'not' or to reverse an action. 'Happy' → 'unhappy' (not happy). 'Do' → 'undo' (reverse doing).
Tip
UN makes it undone — unhappy, unfair, unlike!
Examples
Phonics Rule: Letter D
Sound“d”·/d/
The letter D makes the /d/ sound, like in 'dog', 'day', and 'dig'. The tongue tip touches behind the upper teeth.
D is a voiced alveolar stop. The tongue tip touches the ridge just behind the upper front teeth, then releases with voice. It reliably makes the /d/ sound in almost all positions.
Tip
D is for dog — and dog starts with /d/!
Examples
Phonics Rule: R-Controlled ER
Sound“er”·/ɜːr/
When R comes after E, it makes the “er” sound, like in 'her' and 'fern'.
ER makes the same sound as IR and UR — they all say “er”. 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: ST Blend
Sound“st”·/st/
S and T blend together — you hear both sounds! Like in 'stop' and 'fast'.
The blend ST combines /s/ and /t/ spoken quickly together. It can appear at the beginning or end of a word.
Examples
When the letter A appears in a closed syllable (a syllable that ends with a consonant), it usually makes the short A sound “a”. This is one of the first vowel sounds students learn.
Tip
A says “a” like a cat that sat on a mat.
Examples
Phonics Rule: ND End Blend
Sound“nd”·/nd/
ND at the end of a syllable blends /n/ and /d/ together, like in 'hand', 'sand', and 'send'.
ND is a common end blend (coda blend). The nasal /n/ and voiced stop /d/ are both heard. It appears very frequently in English words.
Tip
ND ends with a d-d-d — hand, sand, send!
Examples
Phonics Rule: Suffix -ING
Sound“ing”·/ɪŋ/
Adding -ING to a verb shows something is happening right now, like 'running' and 'playing'.
The suffix -ing is added to verbs to show an ongoing action (present participle). Sometimes the base word changes: drop silent E ('make' → 'making'), double final consonant ('run' → 'running').
