Definitions for "Osuwari"
"Sit"—the command Kagome uses to nullify Inuyasha's power and send him crashing to the ground. Translated for the anime as "Sit, Boy." Osuwari is only used to tell a dog to sit, and is not the same word used to talk about a person sitting. (So when fanfic writers have Kagome saying "Let's sit down" and Inuyasha crashing to the ground, they're wrong. Not the same word.)
Translates to a 'sit' command. It is the magic word Kagome uses to force Inuyasha to sit, because of the enchanted necklace Kaede placed on him.
