Phonics breakdown
Phonics Rule: Letter V
The letter V makes the /v/ sound, like in 'van', 'vet', and 'vine'. Upper teeth touch the lower lip with voice.
V is a voiced labiodental fricative — the upper front teeth rest on the lower lip while air and voice flow through. It is the voiced partner of F. English words rarely end in V; they usually add an E (have, live, give).
Tip
V is for van — /v/ vibrates your lips!
Examples
Phonics Rule: Short A
The letter A makes a short sound, like in 'cat' and 'bat'.
When the letter A appears in a closed syllable (a syllable that ends with a consonant), it usually makes the short A sound /æ/. This is one of the first vowel sounds students learn.
Tip
A says /æ/ like a cat that sat on a mat.
Examples
Phonics Rule: ST Blend
S and T blend together — you hear both sounds! Like in 'stop' and 'fast'.
The blend ST combines /s/ and /t/ spoken quickly together. It can appear at the beginning or end of a word.
Examples
Phonics Rule: Suffix -LY
Adding -LY to a word usually makes it describe HOW something is done, like 'slowly' and 'quickly'.
The suffix -ly usually turns an adjective into an adverb. 'Slow' → 'slowly' means 'in a slow way'.
