Morphology

extraterrestrial = terrestrial (transparent) = extra + terrestrial

The meaning is directly built from extra- 'outside/beyond' plus terrestrial 'of the Earth'.

Etymology

Extraterrestrial comes from extra 'outside' and terra 'earth', the same terra you see in terrain and territory. So an extraterrestrial is a being or life form 'from outside the Earth', which is why we use it for aliens in stories and science.
