Etymology

Origin of katana

C18: Japanese

Explanation

A Japanese samurai's curved sword was called a katana. In ancient military battles, katana were used in close combat. Samurai traditionally used two types of weapon, the longer, heavier tachi and the katana. With a single-sided, gently curved steel blade and a long grip, the katana was designed to be held with two hands and used in hand-to-hand combat. After Japan's Edo period, katanas were most often used for martial arts practice and ceremonies. The compound word katana is from kata, "one-sided," and na, "blade."
