It's like adding "Your Honor" or "Lord/Lady" to someone's name, elevating them to a position of high regard. It's often used when addressing:
* Deities and spirits: Kami-sama (God), O-kami-sama (Great God)
* Emperors and royalty: Tennō-sama (Emperor)
* Very important people: Sensei-sama (Teacher), Okami-sama (Landlord)
* Customers and clients: Okakemono-sama (Customer)
It's important to note that using "-sama" is very formal and should be used sparingly. It's not appropriate for addressing friends or family members.
Here are some examples:
* "O-kage-sama de" (Thanks to your grace/kindness)
* "O-genki desu ka, Tanaka-sama?" (How are you, Mr./Ms. Tanaka?)
* "Watashi wa, Sato-san desu. Dōzo yoroshiku onegai shimasu." (I am Sato. Nice to meet you.)
Remember, if you're unsure about using "-sama," it's always best to err on the side of caution and use a less formal term.
