Lowercase letters are the smaller versions of uppercase letters, also known as capital letters. They are used more frequently in writing and follow the first letter of a sentence or the first letter of a proper noun. In the English alphabet, there are 26 lowercase letters, which are smaller and sometimes take a slightly different form than their uppercase counterparts. Examples of lowercase letters include a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, and z.
