Characteristics
The most common type of palatal consonant is the extremely common approximant, which ranks as among the ten most common sounds in the world's languages. The nasal is also common, occurring in around 35 percent of the world's languages, in most of which its equivalent obstruent is not the stop, but the affricate . Only a few languages in northern Eurasia, the Americas and central Africa contrast palatal stops with postalveolar affricates - as in Hungarian, Czech, Latvian, Macedonian, Slovak, Turkish and Albanian.
Consonants with other primary articulations may be palatalized, that is, accompanied by the raising of the tongue surface towards the hard palate. For example, English (spelled sh) has such a palatal component, although its primary articulation involves the tip of the tongue and the upper gum (this type of articulation is called palatoalveolar).
In phonology, alveolo-palatal, palatoalveolar and palatovelar consonants are commonly grouped as palatals, since these categories rarely contrast with true palatals. Sometimes palatalized alveolars or dentals can be analyzed in this manner as well.
