Phonics breakdown
Phonics Rule: Prefix PRE-
PRE- means 'before'. 'Preview' means to view something before.
The prefix pre- is added to the start of a word to mean 'before' or 'in advance'. 'View' → 'preview' (view before); 'heat' → 'preheat' (heat before).
Tip
PRE- comes before — preview, predict, preheat!
Examples
Phonics Rule: Letter S
The letter S usually makes the /s/ sound, like in 'sun', 'sit', and 'sock'. Air hisses through a small gap.
S is a voiceless alveolar fricative when it makes the /s/ sound. At the end of many words it can also make a /z/ sound (as in 'dogs' or 'has'). At the start of a word it is always /s/.
Tip
S hisses like a snake — sssssun!
Examples
Phonics Rule: Open Syllable U — /uː/ (Long U)
In an open syllable, when U follows L, R, S, or J it says 'oo' instead of 'yoo' — like in 'su-per' and 'tru-ly'.
Same open-syllable pattern as the companion Open Syllable U (/juː/) rule, but when the lone U follows L, R, S, or J it drops the Y-glide and says pure /uː/ (su-per, ru-by, tru-ly). Same letter, different sound depending on what comes before it.
Tip
After L, R, S, J — U says oo, not yoo!
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 -ED (/d/ sound)
After voiced sounds like /b/, /g/, /n/, -ED says /d/, like in 'played' and 'named'.
After voiced consonants and vowels, -ed says /d/. The E is silent.
Tip
After a buzzy sound, -ED says /d/!
