Palatal consonants are
consonants articulated with the body of the tongue raised against the
hard palate (the middle part of the roof of the mouth). Consonants with the tip of the tongue curled back against the palate are called
retroflex.The most common type of palatal consonant is the extremely common
approximant , which ranks as overall, 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 plosive , but the
affricate . Only a few languages in northern Eurasia, the Americas and central Africa contrast palatal plosives with postalveolar affricates - the only common ones being
Hungarian,
Czech,
Slovak and
Albanian.
