arrow-straight

The compound adjective 'arrow-straight' is a relatively modern formation, leveraging the iconic imagery of an arrow's path. The first element, 'arrow', originates from the Old English term for the projectile, a concept central to hunting and warfare for millennia. The second element, 'straight', derives from the Old English concept of being stretched taut, implying a line without curves or bends. When combined, the term creates a powerful visual metaphor, comparing the ideal of perfect linearity to the imagined trajectory of an arrow shot from a bow, a concept later extended to describe moral or behavioral directness.
