Fingerspitzengefühl
I found this delightful German word in Oliver Reichenstein’s fine piece Learning to see. He writes about design that combines functional and aesthetic value—You don’t get there with cosmetics, you get there by taking care of the details, by polishing and refining what you have. This is ultimately a matter of trained taste, or what German speakers call “Fingerspitzengefühl” (literally, “finger-tip-feeling”). He adds a photo of Jan Tschichold to illustrate.
