Is rapid long or short vowel?

The term "rapid" itself does not refer to the length of a vowel sound. In linguistics, the distinction between long and short vowels is based on the duration of the sound. Long vowels are pronounced for a longer period of time than short vowels. To determine if "rapid" contains a long or short vowel, we need to analyze the pronunciation of each individual vowel in the Word according to the rules of English phonetics.
