Laryngeal consonant in the context of "Glottal consonant"

The Anatolian languages are an extinct branch of Indo-European languages that were spoken in Anatolia. The best known Anatolian language is Hittite, which is considered the earliest-attested Indo-European language.

Undiscovered until the late 19th and early 20th centuries, the Anatolian languages are often believed to be the earliest branch to have split from the Proto Indo-European family. Once discovered, the presence of laryngeal consonants ḫ and ḫḫ in Hittite and Luwian provided support for the laryngeal theory of Proto-Indo-European linguistics. While Hittite attestation ends after the Bronze Age, hieroglyphic Luwian survived until the conquest of the Neo-Hittite kingdoms by the Semitic Assyrian Empire, and alphabetic inscriptions in Anatolian languages are fragmentarily attested until the early first millennium AD, eventually succumbing to the Hellenization of Anatolia as a result of Greek colonisation.

Guttural speech sounds are those with a primary place of articulation near the back of the oral cavity, where it is difficult to distinguish a sound's place of articulation and its phonation. In popular usage it is an imprecise term for sounds produced relatively far back in the vocal tract, such as the German ch or the Arabic ayin, but not simple glottal sounds like h. The term 'guttural language' is used for languages that have such sounds.

As a technical term used by phoneticians and phonologists, guttural has had various definitions. The concept always includes pharyngeal consonants, but may include velar, uvular or laryngeal consonants as well.Guttural sounds are typically consonants, but murmured, pharyngealized, glottalized and strident vowels may be also considered guttural in nature.Some phonologists argue that all post-velar sounds constitute a natural class.

The phonology of the Proto-Indo-European language (PIE) has been reconstructed by linguists, based on the similarities and differences among current and extinct Indo-European languages. Because PIE was not written, linguists must rely on the evidence of its earliest attested descendants, such as Hittite, Sanskrit, Ancient Greek, and Latin, to reconstruct its phonology.

The reconstruction of abstract units of PIE phonological systems (i.e. segments, or phonemes in traditional phonology) is mostly uncontroversial, although areas of dispute remain. Their phonetic interpretation is harder to establish; this pertains especially to the vowels, the so-called laryngeals, the palatal and plain velars and the voiced and voiced aspirated stops.

Dorsal consonants are consonants articulated with the back of the tongue (the dorsum). They include the uvular, velar and, in some cases, alveolo-palatal and palatal consonants. They contrast with coronal consonants, articulated with the flexible front of the tongue, and laryngeal consonants, articulated in the pharyngeal cavity.
