An open syllable is a syllable with a long vowel sound where the vowel is open, meaning there is no consonant after it. For example, the word "me" has an open syllable because the vowel "e" at the end of the syllable is pronounced with a long "e" sound. Other examples of open syllable words include "pa/per," "e/ven," and "o/pen". Open syllables are often found in words with more than one syllable, although there are some one-syllable words that are open syllables like "a," "me," and "I". It is important to teach open syllables to beginning readers because they are a consistent spelling pattern in the English language and can help students learn the long vowel sound. Open syllables are also easy to segment and blend, making them a good starting point for phonics instruction.
