Here's why:
* Short Vowel Sounds: The vowel sound in "rattle" is a short "a" sound, as in "cat" or "hat".
* Long Vowel Sounds: Long vowel sounds are typically represented by the vowel letter followed by a silent "e" at the end of a word (like "rate" or "tale") or by a vowel digraph (like "rain" or "boat").
