Resembling or moving in a twisting, spiral pattern like a corkscrew; having a twisted or helical shape.
From corkscrew (tool for opening wine bottles) plus the suffix -y (meaning 'having the quality of'). The corkscrew itself comes from cork plus screw, referring to the tool's spiral shape used to extract corks.
Pilots and aeronautical engineers use this word to describe dangerous spinning motions—when an airplane gets into an uncontrolled corkscrewy dive, it's one of the most feared emergency situations because the spiral motion makes recovery incredibly difficult.
