  yagÃ¡n (originally yahgan, but also now spelled yaghan, jagan, iakan), also known as yÃ¡mana and hÃ¡usi kÃºta, is one of the indigenous languages of tierra del fuego, spoken by the yagÃ¡n people. it is regarded as a language isolate, although some linguists have attempted to relate it to kawÃ©sqar and chon. along with other fuegian languages, it was among the first south american languages to be recorded by european explorers and missionaries. yahgan was also spoken briefly on keppel island in the falkland islands at a missionary settlement. following the death of 84-year-old emelinda acuÃ±a (1921 â october 12, 2005), only one native speaker remains, cristina calderÃ³n of villa ukika on navarino island, chile. calderÃ³n (often referred to as simply abuela) is the sister-in-law of acuÃ±a. ==phonology== ===vowels=== there are three analyses of the phonological system of yahgan, which differ in many details from one another. the oldest analysis is from the 19th century (prephonological era), by thomas bridges (1894); from the middle of the 20th century haudricourt (1952) and holmer (1953); and towards the end of the 20th century, the last phonological studies were made on this moribund language by guerra eissmann (1990), salas y valencia (1990), and aguilera (2000). {| class="wikitable" ! ! front ! central ! back |- align=center ! close | | | |- align=center ! mid | | | |- align=center ! open | | | |} ===consonants=== {| class="wikitable" ! ! labial ! alveolar ! post-alveolar ! palatal ! velar ! glottal |- align=center ! nasal |  |  | | &nbsp; | &nbsp; | &nbsp; |- align=center ! plosive |  |  |  | |  |  |- align=center ! fricative |  |  |  | &nbsp; | {{
