A: Hold on, if the difference between a dicycle, which uses the greek prefix "di," and a bicycle, which uses the
latin prefix "
bi," is that the two wheels are parallel in a dicycle but are inline in a bicycle, then why aren't all three wheels inline in a tricycle? Is it a combination of a bicycle and dicycle but for three wheels?
B: The
latin and greek numerical prefix for 3 happen to be the same, "tri." So even though it is a
weird hybrid because there are an odd number of wheels, since the numerical prefixes are the same, it doesn't end up mattering. Penta vs quin on the other hand...
A: Oh, so for a sextcycle, the
six wheels should be inline to then?
B: A sextcycle? Yes, but having
six wheels inline make the vehicle to be unreasonably
long and difficult to turn and thus create a situation where an unjustifiable and substantial risk is present.
