strong burst of breath that accompanies either the release or closure of some obstruents
via Wikipedia infobox
In phonetics, aspiration is a strong burst of breath that accompanies either the release or, in the case of preaspiration, the closure of some obstruents. In English, aspirated consonants are allophones in complementary distribution with their unaspirated counterparts, but in some other languages, notably most North American languages, South Asian languages and East Asian languages, the difference is contrastive.
