Do you know what the word Oses means in greeting the fighting arts ?? "The meaning and origin of the word OSS, where did it come and why and how and how it used it" Japanese ..
The word Aws is an abbreviation of the word (Ohio Kazimas), which means Japanese, good morning
The basic principle in choosing this word is that the training was previously starting in the morning, so when entering the exercise, the player said to the coach, Ohio Kazimas, then shortened to Aws (the first letter of Ohio and the last letter of Kazimas) and the word became linked to the exercise even if it started at another time.
It is used to exchange greeting and respect between coaches and players in general as follows:
When you meet or see the coach, we salute him with the word Aws and greet him.
And when a player meets with another player, some of them live with the word Os.
When entering or leaving the training hall (dogo).
When you ask you to greet you, that is, when performing the salutation at the beginning and last of the lesson, and in the matches.
Or as permission, as inquiries, or as an apology from the coach or another player.
Or express the understanding means when the trainer explains one of the points or the movement of what the word Os is used in the sense that I understood.
Or a match for approval, I mean, for example, the trainer asks you, have you exercised at home, and you say to him Osi, I mean, yes, you have exercised. I hope that you will not neglect this greeting inside and outside the training and in talks and discussions. To add a combat character, atmosphere and appreciation to others. Oses for everyone.
