Phonics breakdown
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: Short U
The letter U makes a short sound, like in 'cup' and 'bus'.
When the letter U appears in a closed syllable, it usually makes the short U sound /ʌ/. This sounds like 'uh'.
Tip
U says /ʌ/ like 'uh-oh, what's up?'
Examples
Phonics Rule: Soft SC says /s/
Before E, I, or Y, the SC says just /s/ — the C is soft, like in 'scene' and 'science'.
When SC comes before E, I, or Y, the C goes soft and SC says /s/ (scene, science, scent, scissors, descend). Before other letters SC says /sk/ (scan, score, school). A few words like 'muscle' also have a silent C in SC.
Tip
SC before E, I, Y is soft — you hear /s/ in the science scene!
Examples
Phonics Rule: Letter L
The letter L makes the /l/ sound, like in 'lamp', 'leg', and 'lip'. The tongue tip touches behind the upper teeth.
L is a voiced lateral approximant — the tongue tip touches the ridge behind the upper teeth while air flows around the sides. Double L (ll) makes the same /l/ sound.
Tip
L is for lamp — light it up with /l/!
Examples
Phonics Rule: Suffix -ES
The suffix -ES is added to words ending in S, X, Z, CH, or SH to make them plural or third-person singular.
When a word ends in a hissing or buzzing sound (s, x, z, ch, sh), adding just -S would be hard to say. So -ES is added instead and pronounced /ɪz/ — it adds a syllable. For example: box → boxes, wish → wishes, buzz → buzzes.
Tip
-ES adds a whole extra syllable — box-es, wish-es!
