The words "uppercase" and "lowercase" derive from the way print shops were set up hundreds of years ago. Individual pieces of metal tile were stored in boxes known as cases. Capital letters were preserved in uppercase, even if they were used less frequently. Small letters were discarded when no longer needed.
In computer technology, capitals are used to distinguish words that should be treated differently by the printing process. For example, capital letters will not disappear when printed in black and white, while lowercase letters will.
This difference is important when trying to avoid running out of space on your page. If you use too many small letters, you will need to make more than one pass over the text to get it all printed. This becomes time-consuming and expensive. However, if you use only capitals, then a single pass will do.
Another reason for using capitals is so that readers know what word comes after another. For example, if you are discussing how reading literature has helped you understand people, then it would be correct to say that "reading literature has helped me understand how people think".
Without capitals, this sentence would be incorrect because it is difficult to tell whether "people" is a noun or a verb.
The capital letters of modern English are derived from an Old Roman script employed in the third century AD. Because lowercase letters had not yet been established, capital letters were the only ones utilized. And one more thing... Print shops invented the words "uppercase" and "lowercase." Before that, they was just called "capitals."
The first known use of upper-case letters in Europe was in a book written in Latin by Caelius Aurelianus in about 275 AD. The original text has been lost, but copies of it survived in various European languages. These documents showed that people were already using upper-case letters to distinguish words that needed to be emphasized.
In England, William Caxton published a book in 1477 titled "Recuyell of the Historyes of Troye," which was the first printed work in English. It contained some upper-case letters used to highlight certain words in the story. However, it should be noted that these letters were not standardized at this time and varied from book to book.
Standardized upper-case letters arrived in England around 1550 with the arrival of Elizabeth I. She had a love for classical writings and wanted others to share her enthusiasm for them. So, she commissioned a set of typefaces based on those used by scribes in Italy at the time. These typesfaces included capitals for every word form except "Q" and "X".
Case in letters relates to whether letters are written in a larger uppercase form, also known as majuscule or capital letters, or a smaller lowercase form, also known as minuscule or little letters. The first three letters of the alphabet in uppercase form, for example, are A, B, and C. Those same letters in lowercase form are b, d, and e. Other letters may be mixed, with some written in capital letters and others in lowercase.
There are two types of case: initial and non-initial. Initial case refers to the first place that a letter appears in a word or phrase. Non-initial case refers to any other place in a word or phrase. For example, in the word "presidential," "president" is in initial case while "cialis" is in non-initial case. When writing words down, it is important to keep this distinction in mind; otherwise, you might end up with all capitals or no capitals at all.
Words divisible by four or more but not by seven are usually set in initial case. These include names, titles, and some pronouns. Words divisible by seven are usually set in non-initial case. These include most nouns, adjectives, and verbs.
Set in upper-case letters is the most common setting for words in English.
