Spaghetti is a long, thin form of pasta. It is versatile, popular, and available throughout the Western world. Spaghetti is the plural form of the Italian word spaghetto, which is a diminutive of "spago," meaning "thin string" or "twine". The word "spaghetti" can be literally translated as "little strings."
Most spaghetti sold and consumed is commercially prepared, then dried. Spaghetti is cooked by boiling the pasta with salt in water until soft. The consistency or texture of spaghetti changes as it is cooked. The most popular consistency is al dente which is translated from the Italian as "to the tooth"; that is soft but with texture, sometimes even with bite in the center. Others prefer their spaghetti fully cooked, which gives it a much softer consistency. wikipedia
