Proto-Indo-European
*h₃erbh- "to change allegiance or status". The suffixed form
*orbh-o- meaning "bereft of father" or "deprived of free status" became ancient Greek
ὀρφανός orphanós "orphaned". This became English
orphan thru Late Latin.
It also became Old Slavic
*orbŭ, then Old Church Slavonic
рабъ rabŭ "slave" (a perjoration of "changed status"), then
работа rabota "servitude", then Czech
robota "drudgery, compulsory service". The Czech writer Karel Čapek's 1921 play
R.U.R. was the first appearance of the word
robot meaning "mechanical servant". Karel named his brother
Josef as the inventor of the word.
