An open syllable contains

This description defines a closed syllable, where the presence of a consonant at the end typically results in the vowel sound being short. For example, in the word "cat," the vowel "a" is short due to the closing consonant "t." Thus, this does not fit the definition of an open syllable.

While this structure does involve a long vowel, it describes a syllable pattern that ends with a silent 'e,' which creates a closed syllable effect. The presence of the consonant followed by a silent 'e' alters the pronunciation, making it not an open syllable but rather a specific case of a closed syllable with the silent 'e' modifying the preceding vowel sound.

This structure typically indicates a controlled vowel sound, known as an "r-controlled" vowel, where the 'r' modifies the vowel's pronunciation, often making it short. Examples include "car" or "her," which do not fit the criteria for an open syllable since the vowel sound is altered rather than left unencumbered by consonants.
