Etymology: "Regears" is the third-person singular present form of "regear," which means to fit new gears to a machine or vehicle. The base word is "gear," itself a term with a long and varied past, but "regear" is built simply by adding the prefix "re-," meaning again or anew, to that existing verb. The prefix does the work here. To regear something is to equip it with a fresh set of gears, usually after the old ones have worn out or been replaced to change how the machine performs. A bicycle mechanic who regears a bike swaps in different sprockets and chainrings, and the same logic applies to a car gearbox or a piece of industrial equipment.
