The verbal conjunctor en is different from the nominal conjunctor nanga; en also functions as nominal conjunctor in some sources (see Feature 71 "Noun phrase conjunction and comitative"). While Schumann (1783) notes that en is Bakratongo, it occurs more generally in verbal than in nominal conjunction in sources by other authors. The alternative kaba appears as verbal conjunctor or sentence-initial connective ('and, but'); it does not function as nominal conjunctor.
