Morphology

autochthonous = autochthon (opaque) = auto + chthon + ous

The final step from autochthon to autochthonous is a regular adjectival suffixation with -ous.

Etymology

The word autochthonous comes from Greek parts auto- meaning 'self' and chthon meaning 'earth'. A helpful way to remember it is to think of auto- as in automatic meaning 'self' and 'earth' as the ground, so autochthonous means something born or formed 'in the place itself', native and not moved there.
