Phonics breakdown
Phonics Rule: Prefix UN-
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: 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: 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: Letter T
The letter T makes the /t/ sound, like in 'top', 'tap', and 'ten'. The tongue tip taps behind the upper teeth.
T is a voiceless alveolar stop. The tongue tip touches the ridge behind the upper teeth and releases with a puff of air. Double T (tt) makes the same /t/ sound.
Tip
T taps — touch your tongue to make /t/!
Examples
Phonics Rule: AI Vowel Team
When A and I are together, they say long A, like in 'rain' and 'train'.
The vowel team 'ai' makes the long A sound /eɪ/. It usually appears in the middle of a word. At the end of a word, the same sound is usually spelled 'ay'.
Tip
AI in the middle says long A — rain on the train!
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!
