Palatalization (phonetics)

In phonetics, palatalization (ˌpælətəlaɪˈzeɪʃən, also US-lᵻˈzeɪʃən) or palatization is a way of pronouncing a consonant in which part of the tongue is moved close to the hard palate. Consonants pronounced this way are said to be palatalized and are transcribed in the International Phonetic Alphabet by affixing the letter ⟨j⟩ to the base consonant. Palatalization cannot minimally distinguish words in most dialects of English, but it may do so in languages such as Russian, Japanese, Norwegian (dialects), Võro, and Irish. In technical terms, palatalization refers to the secondary articulation of consonants by which the body of the tongue is raised toward the hard palate and the alveolar ridge during the articulation of the consonant. Such consonants are phonetically palatalized. "Pure" palatalization is a modification to the articulation of a consonant, where the middle of the tongue is raised, and nothing else. It may produce a laminal articulation of otherwise apical consonants such as /t/ and /s/. Phonetically palatalized consonants may vary in their exact realization. Some languages add semivowels before or after the palatalized consonant (onglides or offglides). In such cases, the vowel (especially a non-front vowel) following a palatalized consonant typically has a palatal onglide. In Russian, both plain and palatalized consonant phonemes are found in words like большой bɐljˈʂoj, царь tsarj and Катя ˈkatjə. In Hupa, on the other hand, the palatalization is heard as both an onglide and an offglide. In some cases, the realization of palatalization may change without any corresponding phonemic change. For example, according to Thurneysen, palatalized consonants at the end of a syllable in Old Irish had a corresponding onglide (reflected as in the spelling), which was no longer present in Middle Irish (based on explicit testimony of grammarians of the time). In a few languages, including Skolt Sami and many of the Central Chadic languages, palatalization is a suprasegmental feature that affects the pronunciation of an entire syllable, and it may cause certain vowels to be pronounced more front and consonants to be slightly palatalized.

Palate

The palate (ˈpælᵻt) is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. A similar structure is found in crocodilians, but in most other tetrapods, the oral and nasal cavities are not truly separated. The palate is divided into two parts, the anterior, bony hard palate and the posterior, fleshy soft palate (or velum). Hard palate and Soft palate The maxillary nerve branch of the trigeminal nerve supplies sensory innervation to the palate.

Palatal consonant

Palatals 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 [j], which ranks as among the ten most common sounds in the world's languages. The nasal [ɲ] is also common, occurring in around 35 percent of the world's languages, in most of which its equivalent obstruent is not the stop [c], but the affricate t͡ʃ.

Postalveolar consonant

Postalveolar or post-alveolar consonants are consonants articulated with the tongue near or touching the back of the alveolar ridge. Articulation is farther back in the mouth than the alveolar consonants, which are at the ridge itself, but not as far back as the hard palate, the place of articulation for palatal consonants. Examples of postalveolar consonants are the English palato-alveolar consonants [ʃ] [tʃ] [ʒ] [dʒ], as in the words "ship", "'chill", "vision", and "jump", respectively.
