Gaptan

General information
Gaptan is an extinct language, spoken somewhere between 1200BC and 400BC. Its name derives from the name of the texts which formerly made up the majority of its attested corpus: the Gaptas (religious poems). It is a language isolate (that is, it lacks known relatives) but otherwise has living descendants. The sound system of Gaptan isn't attested in almost any native source as the language itself is written using a logographic orthography; a few of the Gaptas had, after being passed down orally, been written down in non-logographic scripts (primarily Brahmi, Aramaic, only one had been written down in Śāradā) before the language was forgotten and native readings suppressed ancient traditions. Besides its native script, Gaptan was also written in the Zhou bronze script; it can thus also be written with the modern Chinese script (even though it is anachronistic to do so).
