The word transparently means a person who performs a spacewalk, formed by adding the agentive suffix '-er' to the base verb 'spacewalk'.

Etymology

Spacewalker comes from space ('the area outside Earth') and walker ('someone who walks'), so imagine a person 'walking' in space. That's why a spacewalker is an astronaut who goes out of a spacecraft to work or move in outer space.
