J

J is the tenth letter in the modern English alphabet and the ISO basic Latin alphabet. The letter J was used as the swash letter I, used for the letter I at the end of Roman numerals when following another I. In English, both in Received Pronunciation and in General American, the IPA phonetic symbol J corresponds to the semivowel sound in words like you, & yellow & yes. In phonetics and phonology, a semivowel or glide, also known as a non-syllabic voiced, is a sound that is phonetically similar to a vowel sound but functions as the syllable boundary, rather than as the nucleus of a syllable. The English letter J did not come into existence until the end of the Middle Ages
