For a gentle encouragement:
* E wiki wiki! (pronounced eh vee-kee vee-kee) - This means "quickly" or "fast" and is a more general way to encourage someone to speed up.
* E koke! (pronounced eh koh-keh) - This also means "quickly" or "fast" and is a bit more emphatic than "e wiki wiki."
For a more urgent request:
* E wiki wiki loa! (pronounced eh vee-kee vee-kee lo-ah) - This adds "very" to "quickly" to make it more urgent.
* E wiki wiki! Aloha ʻoe! (pronounced eh vee-kee vee-kee, ah-lo-ha oh-eh) - This adds "Aloha ʻoe" (goodbye) to the end, which is a polite way to add a sense of urgency.
Other ways to convey urgency:
* E hele koke! (pronounced eh heh-leh koh-keh) - This literally means "go quickly" and can be used when you want someone to move faster.
* E hoʻokele koke! (pronounced eh ho-oh-keh-leh koh-keh) - This means "drive quickly" and is specific to transportation.
Remember that the best way to express urgency in Hawaiian will depend on the situation and your relationship with the person you are talking to.
