Etymology: The word in the request is a misspelling of "autochthonous," which is the form I'll address. It is built from "autochthon," meaning "native to the soil," with the English suffix "-ous" added to turn it into an adjective. The literal sense is therefore rooted in the ground itself: something that springs from the earth where it stands, rather than arriving from somewhere else. That image of the soil as the source of a people or plant is what gives the term its meaning of "originally from here." Because the first part names the earth and the second part is a common adjective ending, the word is a straightforward combination of two elements, and its sense follows directly from them.
