"abd" means also servant as in servant of god (Abdullah).

Also in slavic languages "slovo" means word, so "slaveni" are ""people who speak (the same language),". But it become "sclavoni" in late latin, since appareantly many slaves were slavic? Should I avoid learning any language which has derived from latin because I'm slavic?

Words have ancient roots, in times where there wasn't yet the concept of political correctness and we still have traces of it in every language.
