Here's why:
* Short Vowel Sound: The vowel sound in "rock" is a short "o" sound, similar to the sound in "hot" or "box."
* Long Vowel Sound: Long vowel sounds are typically represented by a vowel followed by a silent "e" or a double vowel. Examples include "bike," "tree," or "meat."
Therefore, "rock" does not have a long vowel sound because it has a short "o" sound and doesn't follow the patterns for long vowel sounds.
