Who doesn't like Italian food? But would you order it if the menu said "little strings" (spaghetti), "little tongues" (linguine), "little worms" (vermicelli) or "little ribbons" (fettuccine)? In Italian "spago" is used for ordinary household string or twine. So the plural, diminutive form, "little strings", is a good visual description of how the pasta looks on the plate.
