DerechovsTornado

The short answer

Named as opposites in the same language: derecho means 'straight', and tornado was long read as coming from tornar, 'to turn'. Both can flatten a treeline; only the debris field tells you which one did it — rotating damage falls in a converging pattern, straight-line damage all points one way.

Where the confusion comes from

A derecho is basically a very wide tornado, or a hurricane on land.

It is defined by its damage swath and its parent storm, not by the absence of rotation - derecho-producing systems routinely carry embedded mesovortices and can spawn tornadoes. Damage is directed one way along a relatively straight swath — hence 'straight-line wind damage'. It originates from a mesoscale convective system moving faster than the mean wind.
