Wow...This turned out to be even cooler than I thought it was when I first saw it:
Proto Slavic word for man, čelověkъ, is derived from Proto Slavic and further down Proto Indo European words for wheel/cart/chariot and child/clan member/soldier...
Proto-Slavic čelověkъ (man), from...Proto-Balto-Slavic *kelawaikas, (child of a clan).
The first part is from Proto-Indo-European *(s)kwel- (crowd, people), from *kʷel- (to turn, roll > to travel on wheeled vehicles, settle, cultivate; town)...
In Lithuanian we have
kelias (road)
vaikas (child)
What's interesting is that vaikas comes from the PIE root weyk meaning to separate, fight, conquer, overcome...
Now in Slavic languages and Proto-Slavic we have these two words
kolo (spinning circle, wheel), kola (cart, chariot, literally wheels)
vojakъ (soldier) which comes from PIE root weyh meaning to chase...
Put this all together and in Proto Balto Slavic you end up with
men = wheel/cart/chariot + clan members/soldiers/warriors = Indo Europeans...
How old are Balto-Slavic languages again?
