Aerodynamical

Part of speech: adjective

Definitions

1. Concerning the design principles that influence how an object moves through air in order to reduce resistance and enhance efficiency
2. Relating to the study of how forces act on objects in motion through the atmosphere to improve performance and stability
3. Pertaining to the characteristics and behaviors of objects as they interact with air flow, aimed at optimizing movement and reducing drag

Etymology: "Aerodynamical" is a compound built from "aero-" and "dynamical," and its first half comes from a Greek word for air. "Aero-" descends from ancient Greek "aḗr," meaning air or mist, and it became a common English combining form for anything involving the atmosphere and flight. "Dynamical" takes its path from "dunamis," the Greek word for power or force, which gave rise to "dynamic" through French and later to English "dynamical," with the adjective-forming ending "-al" added on top of the older "-ic" form. The result is a word whose two halves come from different sides of the physical world: one from the medium an object moves through, the other from the forces that move it. Put together, they describe how air and motion interact, most often in the design of wings, cars and other objects meant to slip through the atmosphere. The word is a plain technical coinage built from existing parts rather than an invention with a single named inventor.

Synonyms: streamlined, aerodynamic, efficient, sleek, winged
