Word used often by friends & acquaintances
mui muj moj möi müi • interj. • mʌü mœɩ mœɪ mɔɩ mɔy • It's a local variety of 'hi', can also be used as a parting-greeting. I believe it to stem from either 'goedemorgen' (good morning) or 'mooi(e dag)' or something similar (which means beautiful (day)) but this is guesswork on my part.
“Moi, hoe is 't?” Ok, moi hè!
“Hi, how is it?” “Ok, bye”
