What does autochthon mean?
An autochthon is an original inhabitant of a region — someone regarded as having lived there since the earliest times rather than arriving from elsewhere. The word carries a scholarly tone, appearing mainly in anthropology, history, and discussions of indigenous peoples, where it emphasises deep, continuous roots in a homeland. It derives from Greek roots meaning 'from the soil itself,' and ancient Greeks applied it proudly to peoples like the Athenians, whom legend claimed were born from their native earth. In geology the term has a second life: an autochthon is a mass of rock that has stayed where it formed, contrasted with an allochthon that has been pushed into place by tectonic forces. Though rare in everyday speech — the adjective autochthonous is more familiar — autochthon offers writers a precise, dignified way to speak of first peoples or unmoved stone.
An original or aboriginal inhabitant of a place.
"The museum honoured the autochthons whose ancestors first settled the coast."
(Geology) A mass of rock remaining at the site of its formation.
"The thrust sheet rode over an autochthon of ancient basement rock."
The anglicised plural 'autochthons' is standard; the Greek-style 'autochthones' occasionally appears in older scholarly writing.
"Early chroniclers described the autochthons as the land's first people."
In Greek myth the Athenians claimed to be autochthonous — literally born from the very soil they stood on.

Etymology of autochthon
Autochthon comes from Greek autos ('self') combined with chthōn ('earth, soil'), literally meaning 'sprung from that land itself.' English adopted the word in the early seventeenth century, initially in learned and classical contexts describing peoples believed to be earthborn or of immemorial origin. Its geological sense developed later, contrasting autochthonous rock with allochthonous (transported) material. Cognate formations include the adjective autochthonous and the noun autochthony, all built on the same Greek elements.
How autochthon is actually used
A formal, scholarly word used chiefly in anthropology, ethnology, classical studies, and geology. The adjective 'autochthonous' is considerably more common than the noun. Plural is 'autochthons'; the Greek-derived plural 'autochthones' also appears in older texts.
