Words With Remarkable Origins, Vol. 2
During India's first War of Independence (or the Indian Mutiny) in 1857, the British military wore uniforms shaded a light yellowish brown.
How would you describe that shade? The locals called it khaki, which in Hindi and Urdu means "dust-colored."
(These days, of course, pants often called "khakis" come in a range of colors other than dusty brown.)
