The Spanish verb 'volar' (to fly) comes directly from the Latin verb 'volare', which also meant 'to fly'. This is a straightforward inheritance where both the form and meaning have remained remarkably stable over time from Latin to modern Spanish.

Some common Spanish words derived from the same root include 'vuelo' (flight), 'volante' (flying, as in 'hoja volante' - flyer/leaflet), and 'volador' (flying). The noun 'aviador' (aviator) and 'avión' (airplane), while related to flight, come from a different Latin root 'avis' meaning 'bird'.

While English 'fly' comes from Germanic roots rather than Latin, there are several English words related to the Latin 'volare'. These include 'volatile' (easily evaporating, or unpredictable - originally meaning 'flying' or 'fleeting'), 'volley' (originally referring to flight of arrows or birds), and 'volant' (flying or capable of flight, though this is rather rare in modern English). The more common word 'aviation' comes from a different Latin root related to 'bird'.
