English might not be you native or secondary language?
A gear is a (usually) round thing with teeth. Those teeth typically don't spin freely, but connect to another
Because the diameters of the two differ, the gears (plural) exchange rotational speed for torque.
In an old style gearbox, one of these gears is fixed, and we say "first gear" (singular) or "second gear" (singular) to note which gear should connect to the fixed gear.
But you always have gears.
