robot (n.)youdaoicibaDictYouDict
1923, from English translation of 1920 play "R.U.R." ("Rossum's Universal Robots"), by Karel Capek (1890-1938), from Czech robotnik "slave," from robota "forced labor, compulsory service, drudgery," from robotiti "to work, drudge," from an Old Czech source akin to Old Church Slavonic rabota "servitude," from rabu "slave," from Old Slavic *orbu-, from PIE *orbh- "pass from one status to another" (see orphan). The Slavic word thus is a cousin to German Arbeit "work" (Old High German arabeit). According to Rawson the word was popularized by Karel Capek's play, "but was coined by his brother Josef (the two often collaborated), who used it initially in a short story."
share (n.1)youdaoicibaDictYouDict
"portion," Old English scearu "a cutting, shearing, tonsure; a part or division," related to sceran "to cut," from Proto-Germanic *skaro- (cognates: Old High German scara "troop, share of forced labor," German Schar "troop, band," properly "a part of an army," Old Norse skör "rim"), from PIE root *(s)ker- (1) "to cut" (see shear (v.)).

Meaning "part of the capital of a joint stock company" is first attested c. 1600. Share and share alike attested from 1560s. The same Old English noun in the sense "division" led to an obsolete noun share "fork ('division') of the body at the groin; pubic region" (late Old English and Middle English); hence share-bone "pubis" (early 15c.).
