sounds are glottalic ingressives where air is pulled in by a downward movement of the glottis.Click
sounds, i.e. lingual / velaric ingressive sounds, pull air in with a downward movement of the tongue.Allowed Values
"click"

Features:
features
Type:
array
Description
A list of the phonemically distinctive features of this Phoneme. These are what are listed under
diacritics
in the IPA chart. For example, if a language distinguishes between a palatalized/t/
and a plain/t/
, the first should include the featurepalatalized
and the secondplain
(or no features). Note that most features are also a manner of articulation as well, so it up to the linguist to decide when a given phonetic detail is a manner, or when it is a feature (i.e. a diacritic). For example, a language might distinguish phonemically between a palatal plosive/c/
and a palatalized plosive/tʲ/
. The first would listpalatal
as its place of articulation, while the second would listpalatalized
as a distinctive feature. Do not include features here if they are already used for manner, unless your analysis is that this feature is both a manner and a feature of this phoneme, e.g. a palatalized palatal stop. This field is used primarily for consonants, but may also apply to vowels as well (e.g. theclose
andopen
features).Items must be unique:
