"please" is "vennligst" or "vær så snill" in Norwegian. But we rarely use these words compared to how often we use "please" in English. In Norwegian it is better to ask "kan jeg…" (can I…), or just say the sentence without the word "please". Even though it might sound impolite in English, it sounds polite in Norwegian.

Therefore, "Please come here" is "Kan du komme her?" or just "Kom her".

"A hamburger, please" = "Kan jeg få en hamburger?" or just "Én hamburger"
"Please say hello to them from me" = "Kan du hilse dem fra meg?" or "Hils dem fra meg" (å hilse = to greet)
"Yes, please" = "Ja, takk" (literally means "yes, thank you")

"sorry" is "beklager" or "unnskyld". Both are commonly used and they are almost interchangeable, but "beklager" sounds a little bit more formal than "unnskyld", and "unnskyld" can also mean "excuse me".

"Sorry, I can’t help you" = "Beklager, jeg kan ikke hjelpe deg"
"Sorry for eating your piece of cake" = "Unnskyld for at jeg spiste kakestykket ditt"
"Excuse me, where is the toilet?" = "Unnskyld, hvor er toalettet?"
