Here's why:
* Short Vowel Sound: The vowel "o" in "clock" makes a short "o" sound, like in "hot" or "dog".
* Long Vowels: Long vowel sounds are typically associated with vowels that say their name, like "a" in "cake", "e" in "tree", "i" in "bike", "o" in "go", or "u" in "cute".
Let me know if you'd like to know if another word has a long vowel sound!
