O Vowel Words | Short and Long O Vowel Words! In phonetics, a vowel is a sound, such as “ah,” “oh,” or “ooh,” that is produced by the relatively free passage of air through the mouth. Every word in English has at least one vowel. Vowels are classified according to how they are produced.
The three major categories of vowels are monophthongs, diphthongs, and triphthongs. Monophthongs are produced when the airstream from the lungs is not obstructed as it passes through the mouth; they are therefore also sometimes called “unobstructed” or “pure” vowel sounds.
