Phonics breakdown
Phonics Rule: Letter T
The letter T makes the /t/ sound, like in 'top', 'tap', and 'ten'. The tongue tip taps behind the upper teeth.
T is a voiceless alveolar stop. The tongue tip touches the ridge behind the upper teeth and releases with a puff of air. Double T (tt) makes the same /t/ sound.
Tip
T taps — touch your tongue to make /t/!
Examples
Phonics Rule: OUGH Pattern
OUGH can make many different sounds — it must be learned word by word.
OUGH is one of the most irregular patterns in English. There is no rule that predicts which sound a given OUGH word uses, so the rule card shows each variant alongside an example word you can tap to hear. Each word must be memorized.
Tip
OUGH is tricky — listen to each variant and learn the words individually.
Examples
Phonics Rule: Suffix -EST
Adding -EST means 'the most', like 'biggest' and 'fastest'.
The suffix -est makes a superlative — it means 'the most' of something. 'Big' → 'biggest' means the most big of all.
