the.com/line of sight
The straight path your eyes trust, even when the world insists on curving.
means The unobstructed straight path along which someone or something can be seen, or the range within which a target is visible without obstruction.
from A straightforward compound from 'line' (a straight mark or path, from Latin 'linea') and 'sight' (the act or power of seeing, from Old English 'sihth'). It emerged in English as a technical phrase in optics, surveying, and gunnery — anywhere someone needed to say precisely 'the straight imaginary line from the eye (or instrument) to the thing being viewed.' Its military and engineering roots are why it still feels crisp and practical rather than poetic, even though it now gets used loosely for anything from sniper aim to office-cubicle visibility.
