Etymology: "Spacewalked" is the past tense and past participle of "spacewalk", which is simply "space" and "walk" joined together. The compound describes an astronaut leaving a spacecraft to work outside it, moving through the vacuum rather than along a path on the ground. Nothing in the word's making is especially surprising: it is a plain, transparent formation in which each part keeps its everyday sense, and the new meaning comes entirely from the combination. The verb form follows the usual English pattern for regular verbs, adding "-ed" to make the past.
