This is known as a long vowel sound, because it says the ânameâ of the letter. The same goes for the other vowels. A short vowel sound is a vowel sound that does not follow this rule. When reading a word that uses a short vowel sound, will say the sound that the letter can make that is not its actual name. So in the case of âA,â the word âmainâ might have a long âAâ sound because we pronounce the âAâ as /Ä/, whereas the word âmanâ has a short vowel sound.
