Retroflex consonantA retroflex (ˈɹɛtɹoʊflɛks or ˈɹɛtɹəflɛks), apico-domal, or cacuminal (kæˈkjuːmᵻnəl) consonant is a coronal consonant where the tongue has a flat, concave, or even curled shape, and is articulated between the alveolar ridge and the hard palate. They are sometimes referred to as cerebral consonants—especially in Indology. The Latin-derived word retroflex means "bent back"; some retroflex consonants are pronounced with the tongue fully curled back so that articulation involves the underside of the tongue tip (subapical).

Labiodental consonantIn phonetics, labiodentals are consonants articulated with the lower lip and the upper teeth. The labiodental consonants identified by the International Phonetic Alphabet are: The IPA chart shades out labiodental lateral consonants. This is sometimes read as indicating that such sounds are not possible. In fact, the fricatives [f] and [v] often have lateral airflow, but no language makes a distinction for centrality, and the allophony is not noticeable.
Click consonantClick consonants, or clicks, are speech sounds that occur as consonants in many languages of Southern Africa and in three languages of East Africa. Examples familiar to English-speakers are the tut-tut (British spelling) or tsk! tsk! (American spelling) used to express disapproval or pity (IPA [ǀ]), the tchick! used to spur on a horse (IPA [ǁ]), and the clip-clop! sound children make with their tongue to imitate a horse trotting (IPA [ǃ]).
Palatal consonantPalatals 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.
Uvular consonantUvulars are consonants articulated with the back of the tongue against or near the uvula, that is, further back in the mouth than velar consonants. Uvulars may be stops, fricatives, nasals, trills, or approximants, though the IPA does not provide a separate symbol for the approximant, and the symbol for the voiced fricative is used instead. Uvular affricates can certainly be made but are rare: they occur in some southern High-German dialects, as well as in a few African and Native American languages.
ApproximantApproximants are speech sounds that involve the articulators approaching each other but not narrowly enough nor with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no turbulence. This class is composed of sounds like [ɹ] (as in rest) and semivowels like [j] and [w] (as in yes and west, respectively), as well as lateral approximants like [l] (as in less).
Bilabial consonantIn phonetics, a bilabial consonant is a labial consonant articulated with both lips. Bilabial consonants are very common across languages. Only around 0.7% of the world's languages lack bilabial consonants altogether, including Tlingit, Chipewyan, Oneida, and Wichita. The bilabial consonants identified by the International Phonetic Alphabet (IPA) are: Owere Igbo has a six-way contrast among bilabial stops: [p ph ɓ̥ b b̤ ɓ]. The extensions to the IPA also define a ([ʬ]) for smacking the lips together.
Trill consonantIn phonetics, a trill is a consonantal sound produced by vibrations between the active articulator and passive articulator. Standard Spanish as in perro, for example, is an alveolar trill. A trill is made by the articulator being held in place and the airstream causing it to vibrate. Usually a trill vibrates for 2–3 contacts, but may be up to 5, or even more if geminate. However, trills may also be produced with only one contact.
Postalveolar consonantPostalveolar 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.
