What is a Consonant?

Consonants are letters of the alphabet that are not a, e, i, o, and u (vowels). Specifically, consonants are: b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, w, x, y, z. Sometimes the letter ‘y’ is used as a vowel instead of as a consonant. A good rule of thumb to know its use is by its sound in the word. For example, in ‘Betty’, the y makes an e sound; therefore, it is a vowel in that word.
