Phonics breakdown
Phonics Rule: Letter H
The letter H makes the /h/ sound, like in 'hat', 'hop', and 'hen'. It is a soft breath of air.
H is a voiceless glottal fricative — just a puff of air with no friction. It always appears before a vowel and is sometimes silent (as in 'hour' or 'honest').
Tip
H is a puff of air — breathe out and say /h/!
Examples
Phonics Rule: R-Controlled AR
When R comes after A, it changes the sound to /ɑːr/, like in 'car' and 'star'.
When A is followed by R, the R 'bosses' the vowel and changes its sound. Instead of short A or long A, you hear /ɑːr/. R-controlled vowels are sometimes called 'Bossy R'.
Tip
Bossy R takes the car to the farm!
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 -FUL
Adding -FUL means 'full of', like 'helpful' (full of help) and 'beautiful'.
The suffix -ful means 'full of' or 'having the quality of'. Note: the suffix is spelled with one L (-ful), not two (-full).
Tip
FUL means full of — helpful is full of help!
