Decoding English:
Why Letters & Sounds Don’t Always Match
English uses 26 letters to create over 40 distinct sounds. Master the rules of silent letters, hidden sounds, and tricky spellings.
Vocal Units (Vowels)
A, E, I, O, U — and occasionally Y. The engines of syllable formation.
Structural Units
Consonants define the structural boundaries of the acoustic signal.
The Basics
The vowels are A, E, I, O, U (and sometimes Y). All other letters are consonants.
Crucial Rule: There are more than 40 vowel and consonant sounds in English, meaning we often have to combine letters to make a single sound.
