A phonemic orthography is an orthography (system for writing a language) in which the graphemes (written symbols) correspond to the phonemes (significant spoken sounds) of the language. 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; it was once mostly phonemic during the Middle English stage, when the modern spellings originated, but spoken English changed rapidly while the orthography was much more stable, resulting in the modern nonphonemic situation. However, because of their relatively recent modernizations compared to English, the Romanian, Italian, Turkish, Spanish, Finnish, Czech, Latvian and Polish orthographic systems come much closer to being consistent phonemic representations.
In less formal terms, a language with a highly phonemic orthography may be described as having regular 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.
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 a few languages.
A disputed example of an ideally phonemic orthography is the Serbo-Croatian language[ contradictory ]. In its alphabet (Latin as well as Serbian Cyrillic alphabet), there are 30 graphemes, each uniquely corresponding to one of the phonemes. This seemingly perfect yet simple phonemic orthography was achieved in the 19th century—the Cyrillic alphabet first in 1814 by Serbian linguist Vuk Karadžić, and the Latin alphabet in 1830 by Croatian linguist Ljudevit Gaj. Another such ideal phonemic orthography is native to Esperanto, employing the language creator L. L. Zamenhof's then-pronounced principle “one letter, one sound”.
There are two distinct types of deviation from this 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. Common cases of both types of deviation from the ideal are discussed in the following section.
Some ways in which orthographies may deviate from the ideal of one-to-one grapheme-phoneme correspondence are listed below. The first list contains deviations that tend only to make the relation between spelling and pronunciation more complex, without affecting its predictability (see above paragraph).
Pronunciation and spelling still correspond in a predictable way
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).
Pronunciation and spelling do not always correspond in a predictable way
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).
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.
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.
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 ( // and // , respectively), occurring in words like this // (voiced) and thin // (voiceless) respectively, with both written ⟨th⟩.
Languages with a high grapheme-to-phoneme and phoneme-to-grapheme correspondence (excluding exceptions due to loan words and assimilation) include:
Many otherwise phonemic orthographies are slightly defective: Malay (incl. Malaysian and Indonesian), Italian, Lithuanian, Latvian, Welsh, and Kazakh do not fully distinguish their vowels, Serbo-Croatian does not distinguish tone and vowel length, Somali does not distinguish vowel phonation, and graphemes b and v represent the same phoneme in all varieties of Spanish, while in Spanish of the Americas, /s/ can be represented by graphemes s, c, or z. Modern Indo-Aryan languages like Hindi, Punjabi, Gujarati, Maithili and several others feature schwa deletion, where the implicit default vowel is suppressed without being explicitly marked as such. Others, like Marathi, do not have a high grapheme-to-phoneme correspondence for vowel lengths.
French, with its silent letters and its heavy use of nasal vowels and elision, may seem to lack much correspondence between spelling and pronunciation, but its rules on pronunciation, though complex, are consistent and predictable with a fair degree of accuracy. The actual letter-to-phoneme correspondence, however, is often low and a sequence of sounds may have multiple ways of being spelt.
Orthographies such as those of German, Hungarian (mainly phonemic with the exception ly, j representing the same sound, but consonant and vowel length are not always accurate and various spellings reflect etymology, not pronunciation), Portuguese, and modern Greek (written with the Greek alphabet), as well as Korean hangul, are sometimes considered to be of intermediate depth (for example they include many morphophonemic features, as described above).
English orthography is highly non-phonemic. As with many languages spoken over a wide area, it would in any case be hard to construct an orthography that reflected all of the main dialects of English, because of differences in phonological systems (such as between standard British and American English, and between these and Australian English with its bad–lad split, or even between adjacent counties of Britain). The irregularity of English spelling arises partly because the Great Vowel Shift occurred after the orthography was established; partly because English has acquired a large number of loanwords at different times, retaining their original spelling at varying levels; and partly because the regularisation of the spelling (moving away from the situation in which many different spellings were acceptable for the same word) happened arbitrarily over a period without any central plan. However even English has general, albeit complex, rules that predict pronunciation from spelling, and several of these rules are successful most of the time; rules to predict spelling from the pronunciation have a higher failure rate.
Most constructed languages such as Esperanto and Lojban have mostly phonemic orthographies.
The syllabary systems of Japanese (hiragana and katakana) are examples of almost perfectly shallow orthography – exceptions include the use of ぢ and づ (discussed above) and the use of は, を, and へ to represent the sounds わ, お, and え, as relics of historical kana usage.
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.
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 a Turkish alphabet of Latin origin.
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 /t/ sound in the words "table" and "cat" would, in a phonemic orthography, be written with the same character; however, a strictly phonetic script 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 perfect 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 narrow 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 between aspirated and unaspirated consonants, but other languages, like Korean, Bengali and Hindi do. On the other hand, Korean does not distinguish between voiced and voiceless consonants unlike a number of other languages.
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.
An alphabet is a standardized set of basic written symbols or graphemes that represent the phonemes of certain spoken languages. Not all writing systems represent language in this way; in a syllabary, each character represents a syllable, for instance, and logographic systems use characters to represent words, morphemes, or other semantic units.
English orthography is the system of writing conventions used to represent spoken English in written form that allows readers to connect spelling to sound to meaning.
H, or h, is the eighth letter in the ISO basic Latin alphabet. Its name in English is aitch, or regionally haitch.
Morphophonology is the branch of linguistics that studies the interaction between morphological and phonological or phonetic processes. Its chief focus is the sound changes that take place in morphemes when they combine to form words.
An orthography is a set of conventions for writing a language. It includes norms of spelling, hyphenation, capitalization, word breaks, emphasis, and punctuation.
In phonology and linguistics, a phoneme is a unit of sound that distinguishes one word from another in a particular language.
Sinhala script, also known as Sinhalese script, is a writing system used by the Sinhalese people and most Sri Lankans in Sri Lanka and elsewhere to write the Sinhala language, as well as the liturgical languages, Pali and Sanskrit. The Sinhalese Akṣara Mālāva, one of the Brahmic scripts, is a descendant of the Ancient Indian Brahmi script.
In linguistics, specifically phonetics and phonology, schwa is the mid central vowel sound in the middle of the vowel chart, denoted by the IPA symbol, or another vowel sound close to that position. An example in English is the vowel sound of the 〈a〉 in the word about. Schwa in English is mainly found in unstressed positions, but in some other languages it occurs more frequently as a stressed vowel.
A spelling reform is a deliberate, often authoritatively sanctioned or mandated change to spelling rules. Proposals for such reform are fairly common, and over the years, many languages have undergone such reforms. Recent high-profile examples are the German orthography reform of 1996 and the on-off Portuguese spelling reform of 1990, which is still being ratified.
Palauan is a Malayo-Polynesian language native to the Republic of Palau, where it is one of the two official languages, alongside English. It is widely used in day-to-day life in the country. Palauan is not closely related to other Malayo-Polynesian languages and its exact classification within the branch is unclear.
Italian orthography (writing) uses a variant of the Latin alphabet consisting of 21 letters to write the Italian language.
Atong is a Sino-Tibetan language related to Koch, Rabha, Bodo and Garo. It is spoken in the South Garo Hills and West Khasi Hills districts of Meghalaya state in Northeast India, southern Kamrup district in Assam, and adjacent areas in Bangladesh. The correct spelling "Atong" is based on the way the speakers themselves pronounce the name of their language. There is no glottal stop in the name and it is not a tonal language.
The Marshallese language (Marshallese: new orthography Kajin M̧ajeļ or old orthography Kajin Majōl, also known as Ebon, is a Micronesian language spoken in the Marshall Islands. The language is spoken by about 44,000 people in the Marshall Islands, making it the principal language of the country. There are also roughly 6,000 speakers outside of the Marshall Islands, including those in Nauru and the United States.
Russian orthography is formally considered to encompass spelling and punctuation. Russian spelling, which is mostly phonemic in practice, is a mix of morphological and phonetic principles, with a few etymological or historic forms, and occasional grammatical differentiation. The punctuation, originally based on Byzantine Greek, was in the seventeenth and eighteenth centuries reformulated on the French and German models.
In linguistics, vowel length is the perceived length of a vowel sound: the corresponding physical measurement is duration. In some languages vowel length is an important phonemic factor, meaning vowel length can change the meaning of the word, for example in: Arabic, Finnish, Fijian, Kannada, Japanese, Latin, Old English, Scottish Gaelic, and Vietnamese. While vowel length alone does not change word meaning in most dialects of English, it is said to do so in a few dialects, such as Australian English, Lunenburg English, New Zealand English, and South African English. It also plays a lesser phonetic role in Cantonese, unlike in other varieties of Chinese.
Polish orthography is the system of writing the Polish language. The language is written using the Polish alphabet, which derives from the Latin alphabet, but includes some additional letters with diacritics. The orthography is mostly phonetic, or rather phonemic – the written letters correspond in a consistent manner to the sounds, or rather the phonemes, of spoken Polish. For detailed information about the system of phonemes, see Polish phonology.
Czech orthography is a system of rules for correct writing (orthography) in the Czech language.
According to the alphabetic principle, letters and combinations of letters are the symbols used to represent the speech sounds of a language based on systematic and predictable relationships between written letters, symbols, and spoken words. The alphabetic principle is the foundation of any alphabetic writing system. In the education field, it is known as the alphabetic code.
Romanisation of Bengali is the representation of written Bengali language in the Latin script. Various romanisation systems for Bengali are used, most of which do not perfectly represent Bengali pronunciation. While different standards for romanisation have been proposed for Bengali, none has been adopted with the same degree of uniformity as Japanese or Sanskrit.
The orthographic depth of an alphabetic orthography indicates the degree to which a written language deviates from simple one-to-one letter–phoneme correspondence. It depends on how easy it is to predict the pronunciation of a word based on its spelling: shallow orthographies are easy to pronounce based on the written word, and deep orthographies are difficult to pronounce based on how they are written.
