I think that knowing and applying or even mastering the local lingo wherever you travel is a must. Why? Because it gains the people's respect and understanding. In the long run you're less viewed as the 'foreigner' or 'expat' and you'll also win new quality friendships. In a way, I guess travel is not just going to one place, take some pictures, updating your status of course, and go but it's also about expanding your network and keeping in touch with new friends. Here, knowing the local lingo will get you to levels of kinship that you would never expect.
So for those who are about to go to Madagascar, here's some words that I would like to share and I've learnt so far:
