Etymology: "Blowdown" is a compound-style noun built from the verb phrase "blow down," meaning to knock or throw something to the ground by the force of wind. The noun form is deverbal, meaning it was formed by taking the verb and turning it into a thing-word. Foresters and storm reporters use it for an entire stand of trees flattened in one event, so the word names the damage as much as the wind that caused it. The verb "blow down" is itself plain English, combining "blow," which goes back to Old English "blāwan" for moving air, with "down," the direction of falling. The noun simply collects that action into a single event. Nothing about the word depends on an unusual sound change or a named inventor; its history is the straightforward result of putting a familiar verb into noun form.
