A labial–alveolar ejective stop is a type of consonantal sound used in some spoken languages. It is a [t] and [p] pronounced simultaneously and as an ejective. The symbol in the International Phonetic Alphabet that represents this sound is ⟨t͡pʼ⟩. It is found in Abkhaz, Ubykh and some dialects of Lak.^[1]

Features of a voiceless labial–alveolar plosive are:

• Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Since the consonant is also oral, with no nasal outlet, it is a plosive.
• Its place of articulation is labial–alveolar, which means that it is simultaneously articulated with the front part of the tongue against the alveolar ridge and the lips.
• Its phonation is voiceless, which means it is produced without vibrations of the vocal cords.
• It is an oral consonant, which means that air is not allowed to escape through the nose.
• It is a median consonant, which means it is produced by directing the airstream down the midline of the tongue, rather than to the sides.
• The airstream mechanism is ejective (glottalic egressive), which means the air is forced out by pumping the glottis upward.
