J Ro

J, or j, is the tenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its usual name in English is ''jay'' (pronounced ), with a now-uncommon variant ''jy'' ."J", ''Oxford English Dictionary,'' 2nd edition (1989) When used in the International Phonetic Alphabet for the ''y'' sound, it may be called ''yod'' or ''jod'' (pronounced or ).

History

The letter ''J'' used to be used as the swash letter ''I'', used for the letter I at the end of Roman numerals when following another I, as in XXIIJ or xxiij instead of XXIII or xxiii for the Roman numeral twenty-three. A distinctive usage emerged in Middle High German. Gian Giorgio Trissino (1478–1550) was the first to explicitly distinguish I and J as representing separate sounds, in his ''Ɛpistola del Trissino de le lettere nuωvamente aggiunte ne la lingua italiana'' ("Trissino's epistle about the letters recently added in the Italian language") of 1524. Originally, 'I' and 'J' were different shapes for the same letter, both equally representing , , and ; however, Romance languages developed new sounds (from former and ) that came to be represented as 'I' and 'J'; therefore, English J, acquired from the French J, has a sound value quite different from (which represents the initial sound in the English language word "''y''et").

Pronunciation and use

English

In English, most commonly represents the affricate . In Old English, the phoneme was represented orthographically with and . Under the influence of Old French, which had a similar phoneme deriving from Latin , English scribes began to use (later ) to represent word-initial in Old English (for example, ''iest'' and, later ''jest''), while using elsewhere (for example, ''hedge''). Later, many other uses of (later ) were added in loanwords from French and other languages (e.g. ''adjoin'', ''junta''). The first English language book to make a clear distinction between and was the King James Bible 1st Revision Cambridge 1629 and an English grammar book published in 1633. In loan words such as ''bijou'' or '' Dijon'', may represent . In some of these, including ''raj'', '' Azerbaijan'', '' Taj Mahal'', and '' Beijing'', the regular pronunciation is actually closer to the native pronunciation, making the use of an instance of hyperforeignism, a type of hypercorrection. Occasionally, represents the original sound, as in ''Hallelujah'' and '' fjord'' (see Yodh for details). In words of Spanish origin, where represents the voiceless velar fricative (such as ''jalapeño''), English speakers usually approximate with the voiceless glottal fricative .

In English, is the fourth least frequently used letter in words, being more frequent only than , , and . It is, however, quite common in proper nouns, especially personal names.

Other languages

Germanic and Eastern-European languages

The great majority of Germanic languages, such as German, Dutch, Icelandic, Swedish, Danish and Norwegian, use for the palatal approximant , which is usually represented by the letter in English. Notable exceptions are English, Scots and (to a lesser degree) Luxembourgish. also represents in Albanian, and those Uralic, Slavic and Baltic languages that use the Latin alphabet, such as Hungarian, Finnish, Estonian, Polish, Czech, Serbo-Croatian, Slovak, Slovenian, Latvian and Lithuanian. Some related languages, such as Serbo-Croatian and Macedonian, also adopted into the Cyrillic alphabet for the same purpose. Because of this standard, the lower case letter was chosen to be used in the IPA as the phonetic symbol for the sound.

Romance languages

In the Romance languages, has generally developed from its original palatal approximant value in Latin to some kind of fricative. In French, Portuguese, Catalan (except Valencian), and Romanian it has been fronted to the postalveolar fricative (like in English ''measure''). In Valencian and Occitan it has the same sound as in English, . In Spanish, by contrast, it has been both devoiced and backed from an earlier to a present-day or , with the actual phonetic realization depending on the speaker's dialect.

Generally, ⟨j⟩ is not commonly present in modern standard Italian spelling. Only proper nouns (such as Jesi and Letojanni), Latin words (Juventus), or those borrowed from foreign languages have . The proper nouns and Latin words are pronounced as the palatal approximant , while words borrowed from foreign languages tend to follow that language's pronunciation of . Until the 19th century, was used instead of in diphthongs, as a replacement for final ''-ii'', and in vowel groups (as in ''Savoja''); this rule was quite strict in official writing. is also used to render in dialectal spelling, ''e.g.'' Romanesco dialect (garlic; cf. Italian ''aglio'' ). The Italian novelist Luigi Pirandello used in vowel groups in his works written in Italian; he also wrote in his native Sicilian language, which still uses the letter to represent (and sometimes also ʒor j depending on its environment).

Other European Languages

The Maltese language is a Semitic language, not a Romance language; but has been deeply influenced by them (especially Sicilian) and it uses for the sound /j/ (cognate of the Semitic ''yod'').

In Basque, the diaphoneme represented by has a variety of realizations according to the regional dialect: (the last one is typical of Gipuzkoa).

Non-European languages

It represents a voiced palatal plosive in Konkani, Yoruba, and Swahili. In Kiowa, stands for a voiceless alveolar plosive, .

stands for in the romanization systems of most of the Languages of India such as Hindi and Telugu and stands for in the Romanization of Japanese and Korean.

For Chinese languages, stands for in Mandarin Chinese Pinyin system, the unaspirated equivalent of (). In Wade–Giles, stands for Mandarin Chinese . Pe̍h-ōe-jī of Hokkien and Tâi-lô for Taiwanese Hokkien, stands for and , or and , depending on accents. In Jyutping for Cantonese, stands for .

The Royal Thai General System of Transcription does not use the letter , although it is used in some proper names and non-standard transcriptions to represent either or (the latter following Pali/Sanskrit root equivalents).

In romanized Pashto, represents ځ, pronounced .

In Greenlandic and in the ''Qaniujaaqpait'' spelling of the Inuktitut language, is used to transcribe .

Following Spanish usage, represents or similar sounds in many Latin-alphabet-based writing systems for indigenous languages of the Americas, such as in Mayan languages ( ALMG alphabet) and a glottal fricative in some spelling systems used for Aymara.

Computing codes

:¹ Also for encodings based on ASCII, including the DOS, Windows, ISO-8859 and Macintosh families of encodings.

Unicode also has a dotless variant, ȷ (U+0237). It is primarily used in Landsmålsalfabet and in mathematics. It is not intended to be used with diacritics since the normal j is softdotted in Unicode (that is, the dot is removed if a diacritic is to be placed above; Unicode further states that, for example i+ ¨ ≠ ı+¨ and the same holds true for j and ȷ).

In Unicode, a duplicate of 'J' for use as a special phonetic character in historical Greek linguistics is encoded in the Greek script block as ϳ (Unicode U+03F3). It is used to denote the palatal glide in the context of Greek script. It is called "Yot" in the Unicode standard, after the German name of the letter J. An uppercase version of this letter was added to the Unicode Standard at U+037F with the release of version 7.0 in June 2014.

Wingdings smiley issue

In the Wingdings font by Microsoft, the letter "J" is rendered as a smiley face (this is distinct from the Unicode code point U+263A, which renders as ☺︎). In Microsoft applications, ":)" is automatically replaced by a smiley rendered in a specific font face when composing rich text documents or HTML email. This autocorrection feature can be switched off or changed to a Unicode smiley.
