How much of the local language do you need for daily living? Are local language classes/tutors available and affordable?
One local language is French. My French is crappy, but I survived. So can you. Not sure about tutors. - Jul 2019
Basic French is helpful. Plenty of tutors are available and affordable. - Oct 2017
French is a must. - Oct 2017
French is necessary for shopping, setting up internet, buying phone cards and travel. Local languages like Zarma and Hausa can be fun to pick up a few phrases but not needed for daily living. - Aug 2015
French is very useful. Very few people speak English. No need for Zarma if you're just doing normal work/life in Niamey. - Jul 2013
