The word "heady" combines "head" (Old English hēafod, referring to the mind or physical head) with the suffix "-y" (Old English -ig, forming adjectives). Originally, it described the intoxicating effect of alcohol on the head/mind (sense 1). By the 16th century, it extended metaphorically to describe thrilling or impulsive experiences (sense 2) and stubbornness (sense 3, now archaic). The logic traces a path from literal physical effects to abstract emotional or behavioral intensity.
