Phonics breakdown
Phonics Rule: Letter B
Sound“b”·/b/
The letter B makes the /b/ sound, like in 'bat', 'big', and 'bug'. Both lips press together then release.
B is a voiced bilabial stop — both lips press together and release with voice. It always makes the /b/ sound except when silent at the end of words after m (as in 'lamb' or 'comb').
Tip
B looks like a bat — and bat starts with /b/!
Examples
Phonics Rule: OU Diphthong
Sound“ow”·/aʊ/
OU makes the “ow” sound, like in 'out' and 'house'.
OU glides from “ah” into “oo”, which together make the “ow” sound. It usually appears in the middle of a word. OU has several possible sounds, but “ow” is the most common.
Tip
OU — ouch! I'm out of the house!
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 -LESS
Sound“liss”·/lɪs/
The suffix -LESS means 'without'. It turns a noun or verb into an adjective.
-LESS means without: helpless = without help, fearless = without fear, careless = without care. It is always pronounced “liss” and never changes the spelling of the base word.
Tip
-LESS means without — helpless means without help!
