Surface Forms

extraterrestrial positive

Morphology

extraterrestrial = terrestrial (transparent) = extra + terrestrial

Formed by the productive prefix 'extra-' (outside) attached to 'terrestrial' (of the Earth), so the meaning 'outside the Earth' is directly derived.

Etymology

Extraterrestrial breaks into extra 'outside' and terra 'earth', and terra is the same root you see in terrain and territory. So extraterrestrial describes anything that exists or happens 'outside the Earth', like a signal or life from space.
