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 IR
When R comes after I, it makes the /ɜːr/ sound, like in 'bird' and 'first'.
IR makes the same /ɜːr/ sound as ER and UR. There's no difference in pronunciation — only in spelling.
Tip
The bird in a shirt says /ɜːr/!
Examples
Phonics Rule: Letter M
The letter M makes the /m/ sound, like in 'map', 'mud', and 'mop'. Both lips press together with voice through the nose.
M is a voiced bilabial nasal — both lips press together while the voice hums through the nose. Double M (mm) makes the same /m/ sound.
Tip
M hums like mmm — press your lips and hum!
Examples
Phonics Rule: Suffix -NESS
Adding -NESS turns a describing word into a thing, like 'happy' → 'happiness'.
The suffix -ness turns an adjective into a noun. It means 'the state of being [adjective]'. 'Happy' → 'happiness' = the state of being happy.
