Phonics breakdown
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: R-Controlled UR
When R comes after U, it makes the /ɜːr/ sound, like in 'turn' and 'burn'.
UR makes the same /ɜːr/ sound as ER and IR. It's the least common of the three spellings.
Tip
The nurse with fur says /ɜːr/!
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!
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: 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: Schwa
