Phonics breakdown
Phonics Rule: Letter F
The letter F makes the /f/ sound, like in 'fish', 'fun', and 'fox'. The upper teeth touch the lower lip.
F is a voiceless labiodental fricative — the upper front teeth rest on the lower lip while air flows through to make the /f/ sound. It is very consistent.
Tip
F is for fish — and fish starts with /f/!
Examples
Phonics Rule: R-Controlled OR
When R comes after O, it makes the /ɔːr/ sound, like in 'for' and 'corn'.
OR makes the /ɔːr/ sound. Unlike ER/IR/UR which all sound the same, OR has its own distinct sound. The companion rule r_controlled_or_er covers the /ɜːr/ pronunciation after W (word, work).
Tip
OR — the horse in the corner says /ɔːr/!
Examples
Phonics Rule: TH Digraph (Unvoiced)
TH can make a soft sound /θ/, like in 'think' and 'bath'. Just air, no buzz!
The unvoiced TH /θ/ is the quiet, breathy version. Your throat doesn't vibrate. Stick your tongue between your teeth and blow air.
Tip
Unvoiced TH is quiet — think with three teeth!
