glottal, glottis: formed by a constriction in the glottis (the air passage through the larynx or voicebox, between the vocal folds). (See the diagrams of the principal organs of articulation and places of articulation.) The two most common glottal sounds are the glottal stop [] and the glottal fricative [h].

In phonetic transcription, a question mark [2] (?) is sometimes used as a substitute for the standard glottal stop character [], because it is readily accessible on typewriters and in standard fonts. In practical orthographies for the languages of Mexico (as well as some languages elsewhere), it is often written with a saltillo ().
