Not to be confused with Spelling pronunciation or Pronunciation respelling.

A phonemic orthography is an orthography (system for writing a language) in which the graphemes (written symbols) correspond consistently to the language's phonemes (the smallest units of speech that can differentiate words), or more generally to the language's diaphonemes. Natural languages rarely have perfectly phonemic orthographies; a high degree of grapheme–phoneme correspondence can be expected in orthographies based on alphabetic writing systems, but they differ in how complete this correspondence is. English orthography, for example, is alphabetic but highly nonphonemic.

In less formally precise terms, a language with a highly phonemic orthography may be described as having regular spelling or phonetic spelling. Another terminology is that of deep and shallow orthographies, in which the depth of an orthography is the degree to which it diverges from being truly phonemic. The concept can also be applied to nonalphabetic writing systems like syllabaries.

## Ideal phonemic orthography

[edit]

In an ideal phonemic orthography, there would be a complete one-to-one correspondence (bijection) between the graphemes (letters) and the phonemes of the language, and each phoneme would invariably be represented by its corresponding grapheme. So the spelling of a word would unambiguously and transparently indicate its pronunciation, and conversely, a speaker knowing the pronunciation of a word would be able to infer its spelling without any doubt. That ideal situation is rare but exists in Serbo-Croatian.[citation needed]

## Deviations from phonemic orthography

[edit]

There are two distinct types of deviation from the phonemic ideal. In the first case, the exact one-to-one correspondence may be lost (for example, some phoneme may be represented by a digraph instead of a single letter), but the "regularity" is retained: there is still an algorithm (but a more complex one) for predicting the spelling from the pronunciation and vice versa. In the second case, true irregularity is introduced, as certain words come to be spelled and pronounced according to different rules from others, and prediction of spelling from pronunciation and vice versa is no longer possible.

### Case 1: Regular

[edit]

Pronunciation and spelling still correspond in a predictable way

* A phoneme may be represented by a sequence of letters, called a multigraph, rather than by a single letter (as in the case of the digraph ch in French and the trigraph sch in German), that retains predictability only if the multigraph cannot be broken down into smaller units. Some languages use diacritics to distinguish between a digraph and a sequence of individual letters, and others require knowledge of the language to distinguish them; compare goatherd and loather in English.

Examples:

sch versus s-ch in Romansch

ng versus n \+ g in Welsh

ch versus çh in Manx Gaelic: this is a slightly different case where the same digraph is used for two different single phonemes.

ai versus aï in French

This is often due to the use of an alphabet that was originally used for a different language (the Latin alphabet in these examples) and so does not have single letters available for all the phonemes used in the current language (although some orthographies use devices such as diacritics to increase the number of available letters).

* Sometimes, conversely, a single letter may represent a sequence of more than one phoneme (as x can represent the sequence /ks/ in English and other languages).
* Sometimes, the rules of correspondence are more complex and depend on adjacent letters, often as a result of historical sound changes (as with the rules for the pronunciation of ca and ci in Italian and the silent e in English).

### Case 2: Irregular

[edit]

Pronunciation and spelling do not always correspond in a predictable way

* Sometimes, different letters correspond to the same phoneme (for instance u and ó in Polish are both pronounced as the phoneme /u/). That is often for historical reasons (the Polish letters originally stood for different phonemes, which later merged phonologically). That affects the predictability of spelling from pronunciation but not necessarily vice versa. Another example is found in Modern Greek, whose phoneme /i/ can be written in six different ways: ι, η, υ, ει, οι and υι.

In Bengali, the letters, 'শ', 'ষ', and ' স, correspond to the same sound /ʃ/. Moreover, consonant clusters , 'স্ব', 'স্য' , 'শ্ব ', 'শ্ম', 'শ্য', 'ষ্ম ', 'ষ্য', also often have the same pronunciation, /ʃ/ or /ʃʃ/.

* Conversely, a letter or group of letters can correspond to different phonemes in different contexts. For example, th in English can represent /ð/ (as in this) or /θ/ (as in thin), as well as /th/ in transparent compounds (such as goatherd, fathead, cathouse, boathouse) and /t/ (as in Thai, Thames, Thomas, thyme).
* Spelling may otherwise represent a historical pronunciation; orthography does not necessarily keep up with sound changes in the spoken language. For example, both the k and the digraph gh of English knight were once pronounced (the latter is still pronounced in some Scots varieties), but after the loss of their sounds, they no longer represent the word's phonemic structure or its pronunciation.
* Spelling may represent the pronunciation of a different dialect from the one being considered.
* Spellings of loanwords often adhere to or are influenced by the orthography of the source language (as with the English words ballet and fajita, from French and Spanish respectively). With some loanwords, though, regularity is retained either by
* nativizing the pronunciation to match the spelling (as with the Russian word шофёр, from French chauffeur but pronounced [ʂɐˈfʲor] in accordance with the normal rules of Russian vowel reduction; see also spelling pronunciation) or by
* nativizing the spelling (for example, football is spelt fútbol in Spanish and futebol in Portuguese).
* Spelling may reflect a folk etymology (as in the English words hiccough and island, so spelt because of an imagined connection with the words cough and isle), or distant etymology (as in the English word debt in which the silent b was added under the influence of Latin).
* Spelling may reflect morphophonemic structure rather than the purely phonemic (see next section) although it is often also a reflection of historical pronunciation.

Most orthographies do not reflect the changes in pronunciation known as sandhi in which pronunciation is affected by adjacent sounds in neighboring words (written Sanskrit and other Indian languages, however, reflect such changes). A language may also use different sets of symbols or different rules for distinct sets of vocabulary items such as the Japanese hiragana and katakana syllabaries (and the different treatment in English orthography of words derived from Latin and Greek).

## Morphophonemic features

[edit]

Alphabetic orthographies often have features that are morphophonemic rather than purely phonemic. This means that the spelling reflects to some extent the underlying morphological structure of the words, not only their pronunciation. Hence different forms of a morpheme (minimum meaningful unit of language) are often spelt identically or similarly in spite of differences in their pronunciation. That is often for historical reasons; the morphophonemic spelling reflects a previous pronunciation from before historical sound changes that caused the variation in pronunciation of a given morpheme. Such spellings can assist in the recognition of words when reading.

Some examples of morphophonemic features in orthography are described below.

* The English plural morpheme is written -s regardless of whether it is pronounced as /s/ or /z/, e.g. cats and dogs, not cats and dogz. This is because the [s] and [z] sounds are forms of the same underlying morphophoneme, automatically pronounced differently depending on its environment. (However, when this morpheme takes the form /ɪz/, the addition of the vowel is reflected in the spelling: churches, masses.)
* Similarly the English past tense morpheme is written -ed regardless of whether it is pronounced as /d/, /t/ or /ɪd/ (with some exceptions: spilt, knelt).
* Many English words retain spellings that reflect their etymology and morphology rather than their present-day pronunciation. For example, sign and signature include the spelling ⟨sign⟩, which means the same but is pronounced differently in the two words. Other examples are science /saɪ/ vs. conscience /ʃ/, prejudice /prɛ/ vs. prequel /priː/, nation /neɪ/ vs. nationalism /næ/, and special /spɛ/ vs. species /spiː/.
* Phonological assimilation is often not reflected in spelling even in otherwise phonemic orthographies such as Spanish, in which obtener "obtain" and optimista "optimist" are written with b and p, but are commonly neutralized with regard to voicing and pronounced in various ways, such as both [β] in neutral style or both [p] in emphatic pronunciation.[1] On the other hand, Serbo-Croatian (Serbian, Croatian, Bosnian and Montenegrin) spelling reflects assimilation so one writes Србија/Srbija "Serbia" but српски/srpski "Serbian".
* The final-obstruent devoicing that occurs in many languages (such as German, Polish and Russian) is not normally reflected in the spelling. For example, in German, Bad "bath" is spelt with a final ⟨d⟩ even though it is pronounced /t/, thus corresponding to other morphologically related forms such as the verb baden (bathe) in which the d is pronounced /d/. (Compare Rat, raten ("advice", "advise") in which the t is pronounced /t/ in both positions.) Turkish orthography, however, is more strictly phonemic: for example, the imperative of eder "does" is spelled et, as it is pronounced (and the same as the word for "meat"), not *ed, as it would be if German spelling were used.

Korean hangul has changed over the centuries from a highly phonemic to a largely morphophonemic orthography.[citation needed] Japanese kana are almost completely phonemic but have a few morphophonemic aspects, notably in the use of ぢ di and づ du (rather than じ ji and ず zu, their pronunciation in standard Tokyo dialect), when the character is a voicing of an underlying ち or つ. That is from the rendaku sound change combined with the yotsugana merger of formally different morae. The Russian orthography is also mostly morphophonemic, because it does not reflect vowel reduction, consonant assimilation and final-obstruent devoicing. Also, some consonant combinations have silent consonants.

## Defective orthographies

[edit]

A defective orthography is one that is not capable of representing all the phonemes or phonemic distinctions in a language. An example of such a deficiency in English orthography is the lack of distinction between the voiced and voiceless "th" phonemes (/ð/ and /θ/, respectively), occurring in words like this /ˈðɪs/ (voiced) and thin /ˈθɪn/ (voiceless) respectively, with both written ⟨th⟩.

## Realignment of orthography

[edit]

With time, pronunciations change and spellings become out of date, as has happened to English and French. In order to maintain a phonemic orthography such a system would need periodic updating, as has been attempted by various language regulators and proposed by other spelling reformers.

Sometimes the pronunciation of a word changes to match its spelling; this is called a spelling pronunciation. This is most common with loanwords, but occasionally occurs in the case of established native words too.

In some English personal names and place names, the relationship between the spelling of the name and its pronunciation is so distant that associations between phonemes and graphemes cannot be readily identified. Moreover, in many other words, the pronunciation has subsequently evolved from a fixed spelling, so that it has to be said that the phonemes represent the graphemes rather than vice versa. And in much technical jargon, the primary medium of communication is the written language rather than the spoken language, so the phonemes represent the graphemes, and it is unimportant how the word is pronounced. Moreover, the sounds which literate people perceive being heard in a word are significantly influenced by the actual spelling of the word.[2]

Sometimes, countries have the written language undergo a spelling reform to realign the writing with the contemporary spoken language. These can range from simple spelling changes and word forms to switching the entire writing system itself, as when Turkey switched from the Arabic alphabet to the Latin-based Turkish alphabet.

## Phonetic transcription

[edit]

Main article: Phonetic transcription

Methods for phonetic transcription such as the International Phonetic Alphabet (IPA) aim to describe pronunciation in a standard form. They are often used to solve ambiguities in the spelling of written language. They may also be used to write languages with no previous written form. Systems like IPA can be used for phonemic representation or for showing more detailed phonetic information (see Narrow vs. broad transcription).

Phonemic orthographies are different from phonetic transcription; whereas in a phonemic orthography, allophones will usually be represented by the same grapheme, a purely phonetic script would demand that phonetically distinct allophones be distinguished. To take an example from American English: the phoneme /t/ in the words "table" and "cat" would, in both a phonemic orthography and in IPA phonemic transcription, be written with the same character, while phonetic transcription would make a distinction between the aspirated "t" in "table", the flap in "butter", the unaspirated "t" in "stop" and the glottalized "t" in "cat" (not all these allophones exist in all English dialects). In other words, the sound that most English speakers think of as /t/ is really a group of sounds, all pronounced slightly differently depending on where they occur in a word. A perfectly phonemic orthography has one letter per group of sounds (phoneme), with different letters only where the sounds distinguish words (so "bed" is spelled differently from "bet").

A phonetic transcription represents phones, the sounds humans are capable of producing, many of which will often be grouped together as a single phoneme in any given natural language, though the groupings vary across languages. English, for example, does not distinguish phonemically between aspirated and unaspirated consonants, but other languages, like Korean, Bengali and Hindi do.

The sounds of speech of all languages of the world can be written by a rather small universal phonetic alphabet. A standard for this is the International Phonetic Alphabet.
