Etymology: "Wheelbases" is the plural of "wheelbase," a compound formed from "wheel" and "base." The "wheel" half is ancient: it descends from a Proto-Germanic word, "hweulō," which reached English as Old English "hwēol" and became Middle English "whel." The "base" half took a longer road, traveling from ancient Greek "bắsis," meaning a step or a pedestal, through Latin "basis," then Old French "base," and into Middle English. Put together, the compound describes exactly what it sounds like: the span between a vehicle's front and rear axles, the distance the wheels are spaced along its length. The plural form simply counts several such measurements, as when comparing the wheelbases of different car models or the wheelbases of a fleet of trucks.
