What does aerodynamical mean?
'Aerodynamical' is an adjective meaning relating to aerodynamics — the branch of physics concerned with the motion of air and other gases and the forces they exert on objects moving through them. In practice it describes anything shaped, designed, or behaving so as to manage airflow efficiently, from aircraft wings and racing cars to cyclists' postures and building facades. The word is a rare variant of the standard adjective 'aerodynamic', which overwhelmingly dominates contemporary usage in both technical literature and everyday speech; 'aerodynamical' survives chiefly in older scientific texts and occasional British writing. It derives from Greek roots: 'aero-' meaning air and 'dynamis' meaning force or power, combined in the nineteenth-century term 'aerodynamics'. Because it carries no distinct meaning of its own, most editors treat 'aerodynamical' as a stylistic curiosity rather than a separate word, though it remains fully legitimate and understandable wherever it appears.

"The engineers refined the car's aerodynamical profile to reduce drag at highway speeds."
"The aircraft's aerodynamical efficiency improved markedly after the wingtips were redesigned."
"Cyclists adopt a low, tucked posture for purely aerodynamical reasons."
While 'aerodynamic' dominates textbooks and wind tunnels alike, its longer sibling 'aerodynamical' survives as a rare, slightly old-fashioned variant that means exactly the same thing.

Etymology of aerodynamical
'Aerodynamical' combines the Greek-derived elements 'aero-' (air) and 'dynamic' (from Greek 'dynamikos', powerful, itself from 'dynamis', force), via the noun 'aerodynamics', which emerged in the nineteenth century alongside related terms such as 'hydrodynamics' and 'thermodynamics'. The adjective was formed by adding the suffix '-al' to this noun, following the same pattern that produced 'hydrodynamical' and 'thermodynamical'. Over time the shorter form 'aerodynamic' displaced it as the standard adjective.

How aerodynamical is actually used
'Aerodynamical' is considerably rarer than 'aerodynamic', which is the preferred form in modern technical and everyday usage. The '-al' variant appears mostly in older scientific writing and in some British sources; writers today almost always choose 'aerodynamic'.
Easily confused with aerodynamical
'Aerodynamic' is the standard, far more common adjective, while 'aerodynamical' is a rarer variant form carrying the same meaning.
'Hydrodynamical' concerns the motion of liquids (especially water), whereas 'aerodynamical' concerns the motion of gases such as air.
