Each letter of the English alphabet may be written as a small letter (abc...) or as a large or capital letter (ABC...). Here is a full list of capital letters.

In English, we do not use capitals letters very much. We use them mainly for the first letter of sentences, names, days and months as well for some abbreviations. In addition, of course, we always write the first person pronoun as a capital I.

It is not usual to write whole sentences in capitals. A sentence or paragraph written in capitals is extremely difficult to read. Did you ever see a book or newspaper written completely in capitals? Of course not! We cannot easily read large amounts of text in capital letters. Lawyers know that capital letters are difficult to read. That is why some legal texts are written completely in capitals.
