Sometimes we say love, joy, and peace...what is that in Creole and are there any other words the Haitians say altogether as a phrase that are encouraging.

Haitians say: lapè, lanmou, lajwa (peace, love, and joy)
See this link: Peace, Love and Joy


Regarding the second question, I'm not sure I understand it.
Would it been encouraging word they say to each other regarding their collective circumstances?
