Ejective Consonants: Sounds Made with Trapped Air
Most consonants in the world's languages are produced by air flowing outward from the lungs. A puff of air moves up through the larynx, past the vocal cords, and out through the mouth or nose. Ejective consonants break this pattern entirely: the glottis is closed, trapping a pocket of air above the vocal cords, and the larynx rises to compress that air until it bursts out through the oral closure with a distinctive popping quality. The result is a consonant that sounds sharper and more forceful than its non-ejective counterpart.
Where Ejectives Appear
Ejectives are not distributed randomly across the world's languages. Three regions account for the overwhelming majority of languages that use them: the Caucasus Mountains (Georgian, Chechen, Kabardian, Lak), the highland Americas from the Pacific Northwest through Central America to the Andes (Quechua, Amharic, many Mayan languages), and the Horn of Africa (Oromo, Hausa, several Cushitic languages). Some linguists have proposed that altitude plays a role—thinner air at high elevations may make the glottalic mechanism energetically efficient—though this hypothesis remains debated.

The IPA Notation
Ejectives are written with a superscript apostrophe following the base symbol: /pʼ/, /tʼ/, /kʼ/, /tsʼ/, /tʃʼ/. The apostrophe signals the glottalic rather than pulmonic airstream. In languages that contrast ejectives with plain voiceless stops—like Georgian or Amharic—native speakers hear the distinction as clearly as English speakers hear the difference between /p/ and /b/. To a non-speaker, both might initially sound like plain voiceless stops, but the acoustic difference is real and measurable.
Ejective fricatives are rarer but do exist; Hausa has /sʼ/ and some Khoisan languages employ ejective clicks. The category illustrates just how many ways the human vocal tract can generate sound.
