ombudsman (n.)

1959, from Swedish ombudsman, literally "commission man" (specifically in reference to the office of justitieombudsmannen, which hears and investigates complaints by individuals against abuses of the state); cognate with Old Norse umboðsmaðr, from umboð "commission" (from um- "around," from Proto-Germanic umbi, from PIE root *ambhi- "around," + boð "command," from PIE root *bheudh- "be aware, make aware") + maðr "man" (from PIE root *man- (1) "man").
