How do you say thank you in Swahili?

The Swahili Word for "thank you" is asante.

Note: There are two Words. Ahsante or Shukrani. (Ahsante is often spelled asante but standard coastal Swahili spells and pronounces it ahsante. In the Swahili of eastern Congo, the Word is aksante.)

People often use the verb kushukuru: nakushukuru(I thank you), tunakushukuru (we thank you). If thanking more than one person, it becomes Nakushukuruni or Tunakushukuruni (or tunawashukuru for the latter)

The form of the verb ahsante also changes when thanking more than one person: ahsanteni, e.g., Ahsanteni kwa kunipigia kura (thanks to all of you for voting for me).
