Retroflex consonant in the context of "Voiceless alveolar fricative"

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.

Bench (Bencnon, Shenon or Mernon, formerly called Gimira) is a Northern Omotic language of the "Gimojan" subgroup, spoken by about 174,000 people (in 1998) in the Bench Maji Zone of the South West Ethiopia Peoples' Region, in southern Ethiopia, around the towns of Mizan Teferi and Shewa Gimira. In a 2006 dissertation, Christian Rapold described three varieties of Bench (Benchnon, Shenon, and Mernon) as "...mutually intelligible...varieties of one and the same language". Bench is the ancestral language of the Bench people.

In unusual variance from most of the other languages in Africa, Bench has retroflex consonant phonemes. The language is also noteworthy in that it has been claimed to have six phonemic pitch levels in its tone system, one of only a handful of languages in the world that have this many, though it has since been reanalized with five levels. Bench has a whistled form used primarily by male speakers, which permits communication over greater distances than spoken Bench. The whistle can be created using the lips or made from a hollow created with both hands. Additionally, this form of the language may be communicated via the 5-stringed krar.

A voiceless alveolar affricate is a type of affricate consonant pronounced with the tip or blade of the tongue against the alveolar ridge (gum line) just behind the teeth. There are several types with significant perceptual differences:

• The voiceless alveolar sibilant affricate [t͡s] is the most common type, similar to the ts in English cats.
• The voiceless alveolar non-sibilant affricate [t͡θ̠] or [t͡θ͇], using the alveolar diacritic from the Extended IPA, is somewhat similar to the th in some pronunciations of English eighth. It is found as a regional realization of the sequence /tr/ in some Sicilian dialects of Standard Italian.
• The voiceless alveolar lateral affricate [t͡ɬ] is found in certain languages, such as Cherokee, Mexican Spanish, and Nahuatl.
• The voiceless alveolar retracted sibilant affricate [t͡s̺], also called apico-alveolar or grave, has a weak hushing sound reminiscent of retroflex affricates. One language in which it is found is Basque, where it contrasts with a more conventional non-retracted laminal alveolar affricate.

Linguolabials or apicolabials are consonants articulated by placing the tongue tip or blade against the upper lip, which is drawn downward to meet the tongue. They represent one extreme of a coronal articulatory continuum which extends from linguolabial to subapical palatal places of articulation. Cross-linguistically, linguolabial consonants are very rare. They are found in a cluster of languages in Vanuatu, in the Kajoko dialect of Bijago in Guinea-Bissau, in Umotína (a recently extinct Bororoan language of Brazil), and as paralinguistic sounds elsewhere. They are also relatively common in disordered speech, and the diacritic is specifically provided for in the extensions to the IPA.

Linguolabial consonants are transcribed in the International Phonetic Alphabet by adding the "seagull" diacritic, U+033C ◌̼ COMBINING SEAGULL BELOW, to the corresponding alveolar or dental consonant. Pullum & Ladusaw (1996) additionally suggest these sound may be equivalently transcribed with the apical diacritic, U+033A ◌̺ COMBINING INVERTED BRIDGE BELOW, on the corresponding bilabial consonant. However, Olson et al. (2009:64) reject this transcription, as linguolabials may be articulated either apical or laminal. The labial consonants ⟨p᫥, m̼, v̼⟩ have also been used. The choice of the base consonant may depend on whether the author analyses the linguolabial as being phonologically labial or alveolar.

Postalveolar (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.

There are many types of postalveolar sounds—especially among the sibilants. The three primary types are palato-alveolar (such as [ʃ ʒ], weakly palatalized; also alveopalatal), alveolo-palatal (such as [ɕ ʑ], strongly palatalized), and retroflex (such as [ʂ ʐ], unpalatalized). The palato-alveolar and alveolo-palatal subtypes are commonly counted as "palatals" in phonology since they rarely contrast with true palatal consonants.

Klamath (/ˈklæməθ/), also Klamath–Modoc (/ˈklæməθ ˈmoʊdɒk/) and historically Lutuamian (/ˌluːtuˈæmiən/), is a Plateau Penutian language spoken around Klamath Lake in what is now southern Oregon and northern California. It is the traditional language of the Klamath and Modoc peoples, each of whom spoke a dialect of the language. By 1998, only one native speaker remained, and by 2003, this last fluent Klamath speaker who was living in Chiloquin, Oregon, was 92 years old. As of 2006 there were no fluent native speakers of either the Klamath or Modoc dialects; however, as of 2019, revitalization efforts are underway with the goal of creating new speakers.

Klamath is a member of the Plateau Penutian language family, which is in turn a branch of the proposed Penutian language family. Like other proposed Penutian languages, Plateau Penutian languages are rich in ablaut, much like Indo-European and Afro-Asiatic languages. Further evidence for this classification includes some consonant correspondences between Klamath and other alleged Penutian languages. For example, the Proto-Yokuts retroflexes */ʈ ʈʼ/ correspond to Klamath /tʃ tʃʼ/, and the Proto-Yokuts dentals */t̪ t̪ʰ t̪ʼ/ correspond to the Klamath alveolars /t tʰ tʼ/.

A voiced retroflex nasal is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɳ⟩.

Like all the retroflex consonants, the IPA symbol is formed by adding a rightward-pointing hook extending from the bottom of ⟨n⟩, the letter used for the corresponding alveolar consonant. It is similar to ⟨ɲ⟩, the letter for the palatal nasal, which has a leftward-pointing hook extending from the bottom of the left stem, and to ⟨ŋ⟩, the letter for the velar nasal, which has a leftward-pointing hook extending from the bottom of the right stem.
