Here's why:
* The vowel sound in "gravy" is a long "a" sound. It sounds like the "a" in "say" or "day".
* Short vowel sounds are typically represented by a single vowel letter. In "gravy," the "a" is followed by a consonant ("v") and a "y". This combination usually results in a long vowel sound.
Therefore, "gravy" does not have a short vowel sound.
