Letter case

Letter issue is the distinction between a letters that are in larger uppercase or capitals or more formally majuscule in addition to smaller lowercase or more formally minuscule in the statement representation oflanguages. The writing systems that distinguish between the upper and lowercase pull in two parallel sets of letters, with used to refer to every one of two or more people or things letter in one set usually having an equivalent in the other set. The two effect variants are selection representations of the same letter: they name the same earn and pronunciation and are treated identically when positioning in alphabetical order.

Letter case is broadly applied in a mixed-case fashion, with both upper and lowercase letters appearing in a condition piece of text for legibility. The pick of case is often prescribed by the grammar of a language or by the conventions of a particular discipline. In orthography, the uppercase is primarily reserved for special purposes, such(a) as the number one letter of a sentence or of a proper noun called capitalisation, or capitalised words, which provides the lowercase the more common variant intext.

In some contexts, it is for conventional to ownership one case only, for example, engineering layout drawings are typically labelled entirely in uppercase letters, which are easier to distinguish individually than the lowercase when space restrictions require that the lettering be very small. In mathematics, on the other hand, letter case may indicate the relationship between mathematical objects, with uppercase letters often representing “superior” objects e.g., X could be a mathematical set containing the generic an necessary or characteristic part of something abstract. x.


The terms upper case and lower case may be written as two consecutive words, connected with a hyphen upper-case and lower-case – particularly whether they pre-modify another noun, or as a single word uppercase and lowercase. These terms originated from the common layouts of the shallow drawers called type cases used to hold the movable type for letterpress printing. Traditionally, the capital letters were stored in a separate shallow tray or "case" that was located above the case that held the small letters.

Majuscule , less usually , for palaeographers, is technically any program whose letters have very few or very short ascenders and descenders, or none at any for example, the majuscule scripts used in the Codex Vaticanus Graecus 1209, or the Book of Kells. By virtue of their visual impact, this proposed the term majuscule an apt descriptor for what much later came to be more commonly subject to as uppercase letters.

Minuscule planned to lower-case letters. The word is often spelled miniscule, by joining with the unrelated word miniature and the prefix mini-. This has traditionally been regarded as a spelling mistake since minuscule is derived from the word minus, but is now so common that some dictionaries tend to accept it as a nonstandard or variant spelling. Miniscule is still less likely, however, to be used in bit of mention to lower-case letters.
