Morphology

outer + space

The compound 'outer space' is compositionally built from 'outer' (external) + 'space' (the cosmos), so a B1 learner who knows both constituents can infer it refers to the region outside Earth's atmosphere. This is a straightforward descriptive noun phrase and parallels equivalent constructions in many languages, making its meaning transparently derivable from the parts.

Etymology

Outer space comes from the simple idea of outer meaning 'outside' and space meaning an 'empty' area beyond the air around Earth. So, outer space now means the area beyond the air around Earth where stars, planets, and satellites are found.
