Did you see the documentary about the first spacewalker?

Yeah, it was fascinating to see what they experienced out there.

Root Explanation

Spacewalker → It is formed from "space" (from Latin *spatium*, meaning a continuous area or expanse) and "walker" (from Old English *wealcan*, meaning to move or travel). The word "spacewalker" refers to someone who moves or travels in the expanse of space.

Memory Tip

Think of someone moving through the vast "space" (an expanse) and "walking" (moving) — that's what a spacewalker does.
