Phonics breakdown
Phonics Rule: Letter N
The letter N makes the /n/ sound, like in 'net', 'nap', and 'nut'. The tongue tip touches behind the upper teeth.
N is a voiced alveolar nasal — the tongue tip touches the ridge behind the upper teeth while voice hums through the nose. It is one of the most common consonants in English.
Tip
N hums through the nose — say /n/ and feel the buzz!
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: CL Blend
C and L blend together — you hear both sounds! Like in 'class' and 'clean'.
The blend CL combines /k/ and /l/ spoken quickly together.
Examples
Phonics Rule: EAR says /ɪər/
EAR usually makes the /ɪər/ sound, like in 'ear', 'hear', and 'near'.
EAR most often says /ɪər/ (the 'ear' sound): ear, hear, near, year, clear, dear, fear.
Tip
Hear with your ear — hear, near, year!
