A consonant is a sound formed by a closed position of the articulating organs as you hear, for example, with letters , , or
. In forming a consonant the voice is compressed or stopped. Most letters in the English alphabet form consonant sounds. Listen:
A vowel is a clear sound made through an open position of the mouth-channel, which molds or shapes the voice without obstructing its utterance. Vowels sounds are formed using these letters, alone or in combination with other letters; A, E, I, O, U, sometimes Y, W.
Note: For more information about using your mouth to form sounds, search the internet using terms like — articulation mouth pictures.
Vowel sounds are short, long, or occasional. With some exceptions:

The English language is heterogeneous and often different combinations of letters produce the same sound. Study the examples in the table below to see all the ways vowels work together to form the long vowel sounds;
| long A | long E | long I | long O | long U |

When the consonant Y and W work with vowels to produce long or occasional vowel sounds, such that only a vowel sound is produced (the consonant sound disappears), we consider Y and W to be acting like vowels as in pay, bow, key, new. So we say Y and W are sometimes vowels.
Think of a word or syllable like a sandwich: vowels are the core filling (the meat or cheese) that gives the word its sound and flavor, and consonants are the bread holding it together.
No matter how you slice it, you can't have a sandwich without the filling—and you can't have a word without a vowel sound!
Help the learner distinguish between open (vowel) and closed/shaped (consonant) sounds using mouth awareness and audio cues.
Open the interactive story Chasing Chase or use a printed copy. Have paper, a pencil, or a index card ready.
Finish by asking the learner to summarize the lesson in their own words: What does your mouth do during a vowel sound versus a consonant sound? Which two letters are "sometimes" vowels? What happens to a word if you take away all the vowels?
