Fishtailing

Part of speech: verb

Definitions

1. The phenomenon where a vehicle's rear swings out of control while navigating a corner or accelerating is known as losing traction at the rear wheels
2. It refers to the sideways motion of the back end of a vehicle caused by a lack of grip during sharp turns or rapid acceleration
3. The occurrence of a vehicle's back end swerving uncontrollably while turning or speeding up is a result of insufficient traction at the rear wheels

Etymology: "Fishtailing" is the present participle of "fishtail," a verb built from the nouns "fish" and "tail." The compound goes back to Middle English as "fisch tayle," and the image is the one you would expect: the tail of a fish swinging side to side as it propels itself through water. Applied to a vehicle, the same sideways swing describes the rear end sliding out from under the driver when the tires lose grip, which is why the motion looks so much like a fish flicking its tail. The word is a plain transfer of a physical picture rather than a metaphor that drifted far from its roots. The fish's tail never stops being the reference point: a car whose back end wags left and right through a turn is, in effect, behaving like a swimming fish. Automotive use is much later than the Middle English compound, so the mechanical sense is a new application of an old, concrete image.
