Capitalization (North American spelling), or capitalisation (British spelling), is a process to make one letter or more uppercase. The first letter of a sentence is capitalised in many languages, as are the first letters of proper nouns such as names of people and places. In German, however, all nouns are capitalized..
In the Latin alphabet, which is used in English, these are the uppercase or capital letters:
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, Z
These are the lowercase or small letters:
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, z
