Aspirated consonant in the context of "Teth"

In phonetics, ejective consonants are usually voiceless consonants that are pronounced with a glottalic egressive airstream. In the phonology of a particular language, ejectives may contrast with aspirated, voiced and tenuis consonants. Some languages have glottalized sonorants with creaky voice that pattern with ejectives phonologically, and other languages have ejectives that pattern with implosives, which has led to phonologists positing a phonological class of glottalic consonants, which includes ejectives.

Ancient Greek phonology is the reconstructed phonology or pronunciation of Ancient Greek. This article mostly deals with the pronunciation of the standard Attic dialect of the fifth century BC, used by Plato and other Classical Greek writers, and touches on other dialects spoken at the same time or earlier. The pronunciation of Ancient Greek is not known from direct observation, but determined from other types of evidence. Some details regarding the pronunciation of Attic Greek and other Ancient Greek dialects are unknown, but it is generally agreed that Attic Greek had certain features not present in English or Modern Greek, such as a three-way distinction between voiced, voiceless, and aspirated stops (such as /b p pʰ/, as in English "bot, spot, pot"); a distinction between single and double consonants and short and long vowels in most positions in a word; and a word accent that involved pitch.

Koine Greek, the variety of Greek used after the conquests of Alexander the Great in the fourth century BC, is sometimes included in Ancient Greek, but its pronunciation is described in Koine Greek phonology. For disagreements with the reconstruction given here, see below.

Teth, also written as Ṭēth or Tet, is the ninth letter of the Semitic abjads, including Phoenician ṭēt 𐤈, Hebrew, Aramaic ṭēṯ 𐡈, and Syriac ṭēṯ ܛ, and Arabic ṭāʾ ط‎. It is also related to the Ancient North Arabian 𐪗‎‎‎, South Arabian 𐩷, and Geʽez ጠ.

The Phoenician letter also gave rise to the Greek theta (Θ), originally an aspirated voiceless dental stop but now used for the voiceless dental fricative. The Arabic letter (ط) is sometimes transliterated as Tah in English, for example in Arabic script in Unicode.

In phonology, an allophone (/ˈæləfoʊn/ ; from the Greek ἄλλος, állos 'other' and φωνή, phōnē 'voice, sound') is one of multiple possible spoken sounds – or phones – used to pronounce a single phoneme in a particular language. For example, in English, the voiceless plosive [t] (as in stop [ˈstɒp]) and the aspirated form [tʰ] (as in top [ˈtʰɒp]) are allophones for the phoneme /t/, while these two are considered to be different phonemes in some languages such as Central Thai. Similarly, in Spanish, [d] (as in dolor [doˈloɾ]) and [ð] (as in nada [ˈnaða]) are allophones for the phoneme /d/, while these two are considered to be different phonemes in English (as in the difference between dare and there).

The specific allophone selected in a given situation is often predictable from the phonetic context, with such allophones being called positional variants, but some allophones occur in free variation. Replacing a sound by another allophone of the same phoneme usually does not change the meaning of a word, but the result may sound non-native or even unintelligible.

In linguistics, fortis (/ˈfɔːrtɪs/ FOR-tiss; Latin for 'strong') and lenis (/ˈliːnɪs/ , /ˈlɛnɪs/ LEE-niss, LEN-iss; Latin for 'weak'), sometimes identified with 'tense' and 'lax', are pronunciations of consonants with relatively greater and lesser energy, respectively. English has fortis consonants, such as the p in pat, with a corresponding lenis consonant, such as the b in bat. Fortis and lenis consonants may be distinguished by tenseness or other characteristics, such as voicing, aspiration, glottalization, velarization, length, and length of nearby vowels. Fortis and lenis were coined for languages where the contrast between sounds such as 'p' and 'b' does not involve voicing (vibration of the vocal cords).

A voiceless velar plosive or stop is a type of consonantal sound used in almost all spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨k⟩.

A [k] sound is a very common sound cross-linguistically. Most languages have at least a plain [k], and some distinguish more than one variety. Many languages also have a two-way contrast between aspirated and plain [k]. Only a few languages lack a voiceless velar plosive, e.g. Tahitian and Mongolian.

This article deals with the phonology of Avestan. Avestan is one of the Iranian languages and retained archaic voiced alveolar fricatives. It also has fricatives rather than the aspirated series seen in the closely related Indo-Aryan languages.

Kalanga, or TjiKalanga (in Zimbabwe), is a Bantu language spoken by the Kalanga people in Botswana and Zimbabwe which belongs to the Shonic (Shona-Nyai) branch of the Bantu languages, within the Niger-Congo languages. It has an extensive phoneme inventory, which includes palatalised, velarised, aspirated and breathy-voiced consonants, as well as whistled sibilants.

Kalanga is recognized as an official language by the Zimbabwean Constitution of 2013 and is taught in schools in areas where its speakers predominate. The iKalanga language is closely related to the Nambya, TshiVenda, and KheLobedu languages of Zimbabwe and South Africa.
