The alphabet is made up of 26 letters, 5 of which are vowels (a, e, i, o, u) and the rest of which are called consonants.
A consonant is a sound that is made by blocking air from flowing out of the mouth with the teeth, tongue, lips or palate.
The 21 consonant letters in the English alphabet are B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, X, Z, and usually W and Y.
