We can write each letter of the English alphabet 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 capital letters very much. We use them mainly for the first letter of sentences, names, days and months as well as for some abbreviations. 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 very difficult to read. Did you ever see a book written in capital letters? Of course not! We cannot easily read lots of text in capital letters. Lawyers, for example, know that capitals are difficult to read and that is why they often write contracts in capital letters!
