Nko Kumo..meaning of Mandingo words

Futuwoo (mandinka for marraige) but what does it entail...My thinking is that, the first word fuu (to lend) Tuwoo (to stay or remain permanently). Hence Futuwoo use to denote seriousness...In essence the family of the woman allow their daughter to marry but on condition that, the man behaves if not, futuban, the lending period ends.Futuwo (a lending that is continous)I may be wrong..
