Probably - as a response to the painful memories of victimization, the Slavic peoples had created a LEXICON OF EUPHEMISMS as SUBSTITUTE WORDS FOR "SLAV" AND "SLAVE". The Slovak and Czech word for "SLAVE" is "OTROK". "OTROK" is the Slovenian word for "CHILD". The connection between "CHILD" and "SLAVE" emerges again... an archaic Czech word for "CHILD" is "ROBĚ" pronounced "ROBYE". In Russian the word for "CHILD" is "ROBYENOK". Common Slavic word for "SLAVE" is "ROB" (Czech - "ROBOTNIK"). In many Slavic languages the word for "WORK or LABOR" is "ROBOTA"(German- Arbeit, Spanish- Trabajo are cryptograms of Robota). In Czech the word "ROBOTA" has a more limited meaning as "FORCED LABOR-UNDER DURESS". Karel Čapek, the Czech playwright used this root to coin the word "ROBOT" in his play R.U.R. Now, the word "ROBOT" is used around the world for a manufactured or mechanical "SLAVE" or "SERVANT". Indentured "SERVITUDE" is evidently the root word for Lusatian SORBS and the Balkan SERBS. The root of this word harkens back to the Latin "SERVUS". SERBIA used to be spelled SERVIA.
"VASSAL" is another word for a subordinate worker "BOUND" to labor for another. The English word vassal is evidently derived from the Slavic word VAZAL - TIED and/or BOUND.
The constellation of words mentioned above serves to add to the volume of evidence that the Slavs located in the center of Europe were systematically enslaved by the peoples living on their periphery - Greeks, Romans, Arabs, North Africans, Germans and others.
Sclavus, Serf, Serb, Servant, Servus, Sorb, Sluga, Sluha, Vassal, are all examples of words derived from the practice of enslaving the Slavs. Euphemisms were used by the Slavs and their slave-masters to eradicate the connection between the ethnic group and the
abusive relationship. The disconnect between Slavs and Slaves was unsuccessful.
More recent ethnographic evidence supports the fact that both victims and victimizers in the institution of slavery create a lexicon of euphemisms to deal with an unpleasant memory or history. In America it has been less than two centuries since the abolition of slavery. Until very recently "Bell-BOY" was the conventional term for a black man who worked as a luggage handler at a hotel or at a train station. The man may have been 70 years old, but he was still called a "BOY". In a similar way one could get a 80 year old "GIRL" to do laundry, Similarly pejorative terms such as "Bohunk" "Slob", "Lower Slavobian" "Nigger" were used in recent past to refer to people less prestigious background. Wendi, Veneti, Venedi etc. were evidently (at least to some measure) euphemisms for Slav-Slaves.
