Allography, from the
Greek for "other writing", has several meanings which all relate to how
words and
sounds are
written
Writing is a medium of human communication which involves the representation of a language through a system of physically inscribed, mechanically transferred, or digitally represented symbols.

Authorship
An allograph may be the opposite of an
autograph
An autograph is a person's own handwriting or signature. The word ''autograph'' comes from Ancient Greek (, ''autós'', "self" and , ''gráphō'', "write"), and can mean more specifically: Gove, Philip B. (ed.), 1981. ''Webster's Third New Inte ...
– i.e. a person's words or name (
signature) written by someone else.
Script
In
graphemics, the term ''allograph'' denotes any glyphs that are considered variants of a letter or other
grapheme
In linguistics, a grapheme is the smallest functional unit of a writing system.
The word ''grapheme'' is derived and the suffix ''-eme'' by analogy with ''phoneme'' and other names of emic units. The study of graphemes is called ''graphemics' ...
, like a number or punctuation. An obvious example in English (and many other writing systems) is the distinction between
uppercase and lowercase letters. Allographs can vary greatly, without affecting the underlying identity of the grapheme. Even if the word "cat" is rendered as "cAt", it remains recognizable as the sequence of the three graphemes ‹c›, ‹a›, ‹t›.
[The Cambridge Encyclopedia of Language, second edition, Cambridge University Press, 1997, p. 196]
Thus, if a group of individual glyphs (shapes that may or may not represent the same letter) are allographs (they do represent the same letter), they all represent a single grapheme (a single instance of the smallest unit of writing).
Letters and other graphemes can also have huge variations that may be missed by many readers. The letter
g, for example, has two common forms (

s) in different
typefaces, and an enormous variety in people's
handwriting. A positional example of allography is the so-called
long s, a symbol which was once a widely used non-final allograph of the lowercase letter
s. A grapheme variant can acquire a separate meaning in a specialized
writing system. Several such variants have distinct
code points in
Unicode and so ceased to be allographs for some applications.
The fact that handwritten allographs differ so widely from person to person, and even from day to day with the same person, means that
handwriting recognition software is enormously complicated.
Chinese characters
In the
Chinese script
Chinese characters () are logograms developed for the writing of Chinese. In addition, they have been adapted to write other East Asian languages, and remain a key component of the Japanese writing system where they are known as '' kan ...
, there exist several graphemes that have more than one written representation. Chinese typefaces often contain many variants of some graphemes. Different regional standards have adopted certain character variants. For instance:

Orthography
An allograph may also be a smaller fragment of writing, that is a
letter
Letter, letters, or literature may refer to:

* Letterform, the graphic form of a letter of the alphabe ...
or a group of letters, which represents a particular sound. In the words ''cat'' and ''king'', the letters c and k are both allographs of the same sound. This relationship between a letter and a sound is not necessarily fixed, for example in a different word, such as ''city'', c is instead an allograph of an s sound.
Some words use groups of letters to represent a sound. In ''kick'' both k and ck are allographs of the sound that the c in ''cat'' represents. These associations are learned as part of learning to
read and write a
language. However, the development of
phonetic associations is more difficult when deaf children are learning written languages. For example, without auditory knowledge of words, children are unable to associate graphemes with

s; a famous example of allographic humour is that of spelling ''fish'' as ''
ghoti
''Ghoti'' is a creative respelling of the word ''fish'', used to illustrate irregularities in English spelling and pronunciation.
Explanation
The word is intended to be pronounced in the same way (), using these sounds:
* ''gh'', pronounced as ...
''.
The primary reason that we accept all these varieties as representing the same sound or grapheme is that we have been taught to make these associations when learning to read the English language. That is to say, their meaning and correspondence is assigned ''arbitrarily'', by conventions adopted and observed by a particular language community. Many of these associations have to be unlearned if we study a second language whose writing system is based upon, or contains many elements similar to or shared by, our own alphabet or writing system. Very often, the letters one might be comfortable and familiar with are allographs of quite different sounds in the second language. For example, in written Spanish the grapheme ⟨v⟩ will often represent the phoneme /b/, whereas in English this does not occur.
Typography
The term 'allograph' is used to describe the different representations of the same grapheme or character in different typefaces. The resulting
font
In metal typesetting, a font is a particular size, weight and style of a typeface. Each font is a matched set of type, with a piece (a "sort") for each glyph. A typeface consists of a range of such fonts that shared an overall design.

elements may look quite different in shape and style from the reference character or each other, but nevertheless their meaning remains the same.
In
Unicode, a given character is allocated a
code point: all allographs of that character have the same code point and thus the essential meaning is retained irrespective of font choice at time of printing or display.
