open syllable
Core Rule
An open syllable ends with a vowel letter and is not closed by a consonant. The key principle is that the vowel usually takes its long sound (letter name), allowing the voice to flow freely without blockage.
Articulation Guide
Using a /eɪ/ as a model: keep the tongue low to mid, mouth relaxed and open, lips neutral. Let the airflow move smoothly forward with a sustained, clear tone.
Word Analysis
- acre: a-cre, the first syllable is open, so a = /eɪ/.
- agency: a-gen-cy, the initial a forms an open syllable.
- april: a-pril, a appears in an open syllable and keeps its long sound.
Pitfalls
Do not rely on spelling alone. Correct syllable division and stress determine whether a vowel truly functions as an open syllable.
Phonics Breakdown
