Word meaning

I find the study of words and how they are used fascinating .
Today Annie in Little Rock used the word vehicle and I got to wondering how this word evolved and the original meaning. This is what I found on the net.
vehicle
1612, "a medium through which a drug or medicine is administered," 1615 in the sense of "any means of conveying or transmitting," from Fr. véhicule, from L. vehiculum "means of transport, a vehicle," from vehere "to carry," from PIE *wegh- "to go, transport in a vehicle" (cf. O.E. wegan "to carry;" O.N. vegr, O.H.G. weg "way;" M.Du. wagen "wagon;" see wagon). Sense of "cart or other conveyance" first recorded 1656.
I found this book on line and it is a nice site to have in your favorites if you are like me and sometime want to know how a word evolved. Click on the tile and have some fun.
