This one starts with the body before it ever reaches the heart. In medieval classrooms, Latin sensitivus meant something that could receive an impression — a nerve, a skin, a faculty of the soul — and by the 1300s French clerks were already writing sensitif. That same sens family gives us sensible, sensual, and sentiment, so when someone is sensitive they’re living on the same family tree as consent and dissent: all those words orbit the old idea of feeling and judgment. English later stretched the word into stranger corners, from the shy, easily hurt person to the nerve-jangling precision of instruments and, by 1953, the ominous Cold War phrase sensitive information. And if you want a picture you won’t forget, think of the sensitive plant — the mimosa that folds up at a touch — a tiny botanical reminder that some things in life do not just notice the world, they flinch at it.
