Sound

The voiced palatal approximant is a type of consonant used in many spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨j⟩. The equivalent X-SAMPA symbol is j, and in the Americanist phonetic notation it is ⟨y⟩. Because the English name of the letter J, jay, does not start with [j] but with [d͡ʒ] (voiced palato-alveolar affricate), this approximant is sometimes called yod instead, as in the phonological history terms yod-dropping and yod-coalescence.

The palatal approximant can in many cases be considered the semivocalic equivalent of the close front unrounded vowel [i]. The two are almost identical featurally. They alternate with each other in certain languages, such as French, and in the diphthongs of some languages, ⟨j⟩ and ⟨⟩ with the non-syllabic diacritic are used in different transcription systems to represent the same sound.

Some languages, though, have a palatal approximant that is unspecified for rounding, and therefore cannot be considered the semivocalic equivalent of either [i] or its rounded counterpart [y]. An example of such language is Spanish, which distinguishes two palatal approximants: an approximant semivowel [j], which is always unrounded, and an unspecified for rounding approximant consonant [ʝ̞]. Eugenio Martínez Celdrán describes the difference between them as follows:
