Imagine a tiny vowel trapped inside a room with a closed door.
When a consonant stands right behind a vowel, it locks the door and forces the vowel to make its short sound.

The Closed Door Rule

A closed syllable is a word part that has one vowel followed by one or more consonants.
Because the consonant closes the door, the vowel says its short sound like /Δƒ/ in cat, /Δ•/ in bed, /Δ­/ in pig, /ŏ/ in top, or /Ε­/ in sun.
How do we use this secret door trick to spell brand-new words?

Spelling 1-Syllable Words

To spell a closed-syllable word, first say the word out loud and tap out each sound you hear.
Let's spell the word lamp: tap /l/, /Δƒ/, /m/, /p/.
Since the vowel /Δƒ/ is closed in by m and p, we know it uses the single letter a.
