Tachi: Meaning (information, definition, explanation, facts)

Tati is a northwestern Iranian language and an alternate spelling (Kunrei-shiki) of the main topic of this article.

Tachi (達 or たち) is also a suffix used in the Japanese language to indicate that a word is plural. See the article on Japanese grammar for details.

There is also a Native American group known as the Tachi tribe.

The tachi (太刀) is a Japanese sword, generally more curved and slightly longer than the katana. As opposed to the traditional manner of wearing the katana, it was worn hung from the belt with cutting-edge down, and usually used by cavalry. The longest of these tachi in existence is more than 2 meters in length but believed to be ceremonial.

It was the predecessor to the katana as the battle-blade of feudal Japan's buke warrior class, and as it evolved into the later design, the two were often differentiated from each other only by how they were worn. In later Japanese feudal history, during the Sengoku and Edo periods, certain high-ranking warriors of what became the ruling class would wear their sword tachi-style (edge-downward), rather than with the saya (scabbard) thrust through the obi (belt) with the edge upward.
