What is a vowel?

Definition

A vowel is an open-mouthed speech sound with free air flow, and a letter that spells one: a, e, i, o, u, and y in words like gym.

English has five main vowel letters but about 15 to 20 vowel sounds, depending on accent. That mismatch is why vowels cause most reading errors. Each vowel letter has a short sound, a long sound and several others in teams and with r.

Every syllable has one vowel sound, so the vowel is the center of every word a student reads. When a student misreads a word, look at the vowel first. More often than not, the consonants are right and the vowel is wrong.

Sequences teach short vowels first, then long vowels with silent e, then vowel teams, r-controlled vowels and diphthongs. Each step adds new spellings for vowel sounds.

In a lesson

Write cap, cape and carp. The student reads all three and notices that only the vowel sound changes, while c and p stay the same.

Examples

Each word with its spelling units, one per sound.

  • capec·a_e·p
  • carpc·ar·p
  • gymg·y·m

Words come from our lexicon, checked against a pronouncing dictionary. Words a student sees in our assessments are left out.

Why does this matter for the record?

Track vowel errors in your notes by the sound the student said and the sound they should have said. Patterns appear quickly.
