Ejective consonantIn 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.
Dental consonantA dental consonant is a consonant articulated with the tongue against the upper teeth, such as /θ/, /ð/. In some languages, dentals are distinguished from other groups, such as alveolar consonants, in which the tongue contacts the gum ridge. Dental consonants share acoustic similarity and in Latin script are generally written with consistent symbols (e.g. t, d, n). In the International Phonetic Alphabet, the diacritic for dental consonant is . When there is no room under the letter, it may be placed above, using the character , such as in /p͆/.
Igbo languageIgbo (ˈiːboʊ , USalsoˈɪɡboʊ ; Igbo: Ásụ̀sụ́ Ìgbò ásʊ̀sʊ̀ ìɡ͡bò) is the principal native language cluster of the Igbo people, a meta-ethnicity from Southern Nigeria. The number of Igboid languages depends on how one classifies a language versus a dialect, so there could be around 15 different Igboid languages. The core Igbo cluster or Igbo proper is generally thought to be one language but there is limited mutual intelligibility between the different groupings (north, west, south and east).
Thai languageThai, or Central Thai (historically Siamese; ภาษาไทย), is a Tai language of the Kra–Dai language family spoken by the Central Thai people and a vast majority of Thai Chinese. It is the sole official language of Thailand. Thai is the most spoken of over 60 languages of Thailand by both number of native and overall speakers. Over half of its vocabulary is derived from or borrowed from Pali, Sanskrit, Mon and Old Khmer. It is a tonal and analytic language. Thai has a complex orthography and system of relational markers.
AffricateAn affricate is a consonant that begins as a stop and releases as a fricative, generally with the same place of articulation (most often coronal). It is often difficult to decide if a stop and fricative form a single phoneme or a consonant pair. English has two affricate phonemes, /t͡ʃ/ and /d͡ʒ/, often spelled ch and j, respectively. The English sounds spelled "ch" and "j" (broadly transcribed as [t͡ʃ] and [d͡ʒ] in the IPA), German and Italian z [t͡s] and Italian z [d͡z] are typical affricates, and sounds like these are fairly common in the world's languages, as are other affricates with similar sounds, such as those in Polish and Chinese.
Manner of articulationIn articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators (speech organs such as the tongue, lips, and palate) when making a speech sound. One parameter of manner is stricture, that is, how closely the speech organs approach one another. Others include those involved in the r-like sounds (taps and trills), and the sibilancy of fricatives.
