<Ul> <Li> </Li> <Li> </Li> <Li> </Li> </Ul> <P> J is the tenth letter in the modern English alphabet and the ISO basic Latin alphabet . Its normal name in English is jay / dʒ eɪ / or, now uncommonly, jy / dʒ aɪ / . When used for the palatal approximant, it may be called yod (/ jɒd / or / joʊd /) or yot (/ jɒt / or / joʊt /). </P> <P> The letter J originated as a 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 representing 23 . 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 / i /, / iː /, and / j /; but, Romance languages developed new sounds (from former / j / and / ɡ /) that came to be represented as' I' and' J'; therefore, English J, acquired from the French J, has a sound value quite different from / j / (which represents the initial sound in the English word "yet"). </P> <P> In English, ⟨ j ⟩ most commonly represents the affricate / dʒ / . In Old English, the phoneme / dʒ / was represented orthographically with ⟨ cg ⟩ and ⟨ cȝ ⟩ . Under the influence of Old French, which had a similar phoneme deriving from Latin / j /, English scribes began to use ⟨ i ⟩ (later ⟨ j ⟩) to represent word - initial / dʒ / in Old English (for example, iest and, later jest), while using ⟨ dg ⟩ elsewhere (for example, hedge). Later, many other uses of ⟨ i ⟩ (later ⟨ j ⟩) were added in loanwords from French and other languages (e.g. adjoin, junta). The first English language book to make a clear distinction between ⟨ i ⟩ and ⟨ j ⟩ was published in 1633 . In loan words such as raj, ⟨ j ⟩ may represent / ʒ / . In some of these, including raj, Azerbaijan, Taj Mahal, and Beijing, the regular pronunciation / dʒ / is actually closer to the native pronunciation, making the use of / ʒ / an instance of a hyperforeignism . Occasionally, ⟨ j ⟩ represents the original / j / sound, as in Hallelujah and fjord (see Yodh for details). In words of Spanish origin, where ⟨ j ⟩ represents the voiceless velar fricative (x) (such as jalapeño), English speakers usually approximate with the voiceless glottal fricative / h / . </P>
